THE USW-210P LOUDSPEAKER
The USW-210P compact narrow subwoofer provides robust, extended low frequency response for installed sound applications that require convincing bass impact from a slender, low profile loudspeaker. Its dual-driver configuration permits a narrow form factor that fits into restricted architectural spaces to produce output levels equal to or exceeding systems with single 12-inch (or larger) drivers. Its slanted connector panel enables flush-mounting the cabinet against wall surfaces, reducing required installation depth to 12 inches (30.5 cm), including connectors.
The USW-210P subwoofer is ideal for installations requiring high performance and versatility along with an appealing, discreet aesthetic appearance. The USW-210P integrates easily with other Meyer Sound loudspeaker systems, such as CALTM and ULTRA Series loudspeakers.
The USW-210P has an operating frequency range of 30140 Hz with a linear peak SPL of 126 dB (measured in half-space at 4 m and referred to 1 m using M-noise). The long skinny bass reflex cabinet employs the same port design as Meyer Sound's flagship 1100-LFC low frequency control element for high efficiency and low port distortion.

USW-210P OPERATING INSTRUCTIONS

INTEGRATED AMPLIFIER AND PROCESSING
A self-powered loudspeaker, the USW-210P cabinet houses a two-channel Class D power amplifier. The audio signal is processed with correction filters for flat frequency and phase responses, and by driver protection circuitry. The amplifier/processing package incorporates Meyer Sound's Intelligent AC which auto-selects the correct operating voltage, suppresses high voltage transients, filters EMI and provides soft-start power-up. The USW-210P cabinet provides audio XLR and powerCON 20 input and looping output connectors.
An optional RMSTM remote monitoring system module provides comprehensive monitoring of loudspeaker parameters from a host computer running Compass Control Software.
The USW-210P loudspeaker's on-board amplifier is convection cooled.

Figure 2: USW-210P with MUB-USW-210P (ceiling mount)

NOTE: Complete acoustical, electrical and physical specifications are covered in Appendix C on page 35.

INTEGRATED RIGGING POINTS
Meyer Sound constructs the USW-210P cabinet from premium multi-ply birch coated with a slightly textured black finish and includes a stamped-steel grille to protect the drivers. Weather protection and custom color finishes for specific cosmetic requirements are available options.
With its versatile shape, the USW-210P can be placed on the ground in a horizontal or vertical position to accommodate installation requirements.
The USW-210P comes standard with M8 mounting points at the top and bottom for use with the optional U-bracket that facilitates wall or ceiling mounting.
In addition, an optional aluminum base plate is available to enhance stability when placing the USW-210P free-standing vertically. This base plate can attach to either end of the loudspeaker, so that the connectors can be oriented at either the top or the bottom when it is free-standing.

CHAPTER 2: POWER REQUIREMENTS

The USW-210P subwoofer combines advanced loudspeaker technology with equally advanced power capabilities. Understanding power distribution, voltage and current requirements, and electrical safety guidelines is critical for the safe operation of the device.

to a single line and common neutral and earth/ground lines. This system delivers 120 V AC to each loudspeaker.

Loudspeaker (120 V AC)

AC POWER DISTRIBUTION
All components in an audio system (self-powered loudspeakers, mixing consoles, and processors) must be properly connected to an AC power distribution system, ensuring that AC line polarity is preserved and that all grounding points are connected to a single node or common point using the same cable gauge (or larger) as the neutral and line cables.
CAUTION: Make sure the voltage received by ! the USW-210P loudspeaker remains within its 90264 V AC operating range. In addition, the ground line must always be used for safety reasons and the line-to-ground voltage should never exceed 250 V AC (typically 120 V AC from line to ground).

Line-Line-Earth/Ground Figure 5 illustrates a 120 V AC, 3-phase Wye distribution system with each loudspeaker connected to two lines and a common earth/ground line. This configuration is possible because USW-210P tolerates elevated voltages from the ground line and does not require a neutral line. This system delivers 208 V AC to each loudspeaker.

CAUTION: Before applying AC power to any
! Meyer Sound self-powered loudspeaker, make
sure that the voltage potential difference between the neutral and earth-ground lines is less than 5 V AC when using single-phase AC wiring.
NOTE: Improper grounding of connections between loudspeakers and the rest of the audio system may produce noise or hum, or cause serious damage to the input and output stages of the system's electronic components.

Figure 5: 120 V AC, 3-Phase Wye System (Two Lines to Loudspeakers)
TIP: The 120 V AC, 3-phase Wye system with two lines is recommended because it allows loudspeakers to draw less current than with singleline systems, thereby reducing voltage drop due to cable resistance. It also excludes the potential of varying ground to neutral voltages producing an audible hum.

CAUTION: For 230 V AC, 3-phase Wye ! systems, never connect two lines to the AC input of USW-210P, as the resulting voltage would exceed the upper voltage limit (275 V AC) and will damage the loudspeaker.

AC CONNECTORS
The USW-210P user panel includes two powerCON 20 connectors (Figure 7), one for AC Input (blue) and one for AC Loop Output (gray).

Figure 7: AC Input (Left) and AC Loop Output (Right) Connectors
AC Input (Blue)
The blue AC Input connector supplies power to USW-210P. The 3-conductor powerCON 20 is rated at 20 A and uses a locking connector that prevents accidental disconnections. A 10-foot AC power cable, rated at 15 A, is included with each loudspeaker. If the included AC power cable is replaced, make sure to use a cable with the appropriate power plug (on the other end) for the region where the unit will be operated. USW-210P requires a

grounded outlet. To operate safely and effectively, it is extremely important that the entire system be properly grounded.
The AC Input connector also supplies power to any additional loudspeakers connected to the loudspeaker's gray Loop Output connector.
CAUTION: When looping AC power for ! loudspeakers, do not exceed the current capability of the AC Input connector (20 A) or the included AC power cable (15 A). Consider the total current draw for all loudspeakers on the circuit, including the first loudspeaker (Table 1).

AC Loop Output (Gray)

The gray AC Loop Output connector allows multiple USW-210P to be looped and powered from a single power source. The 3-conductor powerCON 20 is rated at 20 A and uses a locking connector that prevents accidental disconnections. For applications that require multiple USW-210P, connect the AC Loop Output of the first loudspeaker to the AC Input of the second loudspeaker and so forth.

The maximum number of loudspeakers that can be looped from the AC Loop Output connector is determined by the voltage of the power source, the current draw of the looped loudspeakers, the circuit breaker rating, and the rating of the AC power cable connected to the first USW-210P loudspeaker (Table 1).

NOTE: Current draw for USW-210P is dynamic and fluctuates as operating levels change. The indicated number of loudspeakers that can be looped assumes that operating levels are normal and not such that loudspeakers are constantly limiting.

USW-210P ships with a gray powerCON 20 cable mount connector, rated at 20 A, for assembling AC looping cables. Assembled 1-meter AC looping cables (PN 28.115.032.03) are also available from Meyer Sound.

CHAPTER 2: POWER REQUIREMENTS

WIRING AC POWER CABLES
USW-210P ships with a gray powerCON 20 cable mount connector, rated at 20 A, for assembling AC looping cables (Figure 8). The pins on the powerCON 20 cable mount connector are labeled as follows:

CAUTION: When wiring AC power cables and ! distribution systems, it is important to preserve AC line polarity and connect the earth ground at both ends of the cable. USW-210P requires a grounded connection. Always use a grounded outlet and plug. It is extremely important that the system be properly grounded to operate safely and properly. Do not ground-lift the AC cable.

VOLTAGE REQUIREMENTS
USW-210P operates as intended when receiving AC voltage within the following range:
· 90264 V AC, 5060 Hz
If the voltage drops below 90 V, the loudspeaker uses stored power to continue operating temporarily; the loudspeaker powers off if the voltage does not return to its operating range.
If the voltage rises above 275 V, the power supply could become damaged.
CAUTION: The power source for USW-210P ! should always operate within the required operating range, at least a few volts from the upper and lower limits. This approach ensures that AC voltage variations from the service entry--or peak voltage drops due to cable runs--will not cause the loudspeaker's amplifier to cycle on and off or cause damage to the power supply.
CURRENT REQUIREMENTS
Current draw for loudspeakers is dynamic and fluctuates as operating levels change. Because different cables and circuit breakers heat up at varying rates, it is important to understand the following types of current ratings and how they affect circuit breaker and cable specifications.
· Idle Current -- The maximum rms current during idle periods.
· Maximum Long-Term Continuous Current -- The maximum rms current during a period of at least 10 seconds. The maximum long-term continuous current is used to calculate temperature increases for cables and to ensure that the size and gauge of each cable conforms to electrical code standards. This current rating is also used to select appropriately rated, slowreacting thermal breakers, which are recommended for loudspeaker power distribution. In addition, the maximum long-term continuous current can be used to calculate the AC looping capability for USW-210P loudspeakers.
· Burst Current -- The maximum rms current during a period of around 1 second. The burst current is used as a rating for magnetic breakers. It is also used for calculating the peak voltage drop in long AC cable runs according to the following formula:

USW-210P OPERATING INSTRUCTIONS

V pk (drop) = I pk x R (cable total)

· Maximum Instantaneous Peak Current -- A rating for fast-reacting magnetic breakers.

Use the information in Table 3 to select the appropriate cable gauge and circuit breaker ratings for the system's operating voltage.

Table 3: USW-210P Current Draw

Current Draw

115 V AC

230 V AC

Burst

4.5 A rms 2.1 A rms 4.8 A rms

Maximum Instantaneous Peak

9.7 A rms

4.6 A rms 10.8 A rms

The minimum electrical service amperage required by a loudspeaker system is the sum of the maximum long-term continuous current for all loudspeakers. An additional 30 percent above the combined Maximum Long-Term Continuous amperages is recommended to prevent peak voltage drops at the service entry.

NOTE: For best performance, the AC cable voltage drop should not exceed 10 V (10 percent at 115 V and 5 percent at 230 V). This approach ensures that the AC voltage variations from the service entry--or peak voltage drops due to longer cable runs--do not cause the amplifier to cycle on and off.

Powering on USW-210P
When powering on USW-210P, the following startup events take place over several seconds.
1. Audio output is muted.
2. Voltage is detected and the power supply mode is automatically adjusted as necessary.
3. The power supply ramps up.
4. On the user panel, the On/Status LED flashes multiple colors successively.
5. The On/Status LED turns solid green, indicating the loudspeaker is unmuted and ready to output audio.
CAUTION: If the On/Status LED does not turn ! solid green, or the USW-210P does not output audio after 10 seconds, remove AC power immediately and verify that the voltage is within the required range. If the problem persists, contact Meyer Sound Technical Support.

INTELLIGENT AC POWER SUPPLY
USW-210P's Intelligent ACTM power supply automatically selects the correct operating voltage (allowing the loudspeaker to be used internationally without manually setting voltage switches), eliminates high inrush currents with soft-start power up, suppresses high-voltage transients up to several kilovolts, filters common mode and differential mode radio frequencies (EMI), and sustains operation temporarily during low-voltage periods.

ELECTRICAL SAFETY GUIDELINES
Make sure to observe the following important electrical and safety guidelines. · The powerCON 20 connector should not be engaged or
disengaged when under load or energized. Either de-energize or disconnect the other end of the cable. · USW-210P requires a grounded outlet. Always use a grounded outlet and plug.
Earth ground
Chassis ground
· Do not use a ground-lifting adapter or cut the AC cable ground pin.
· Do not exceed the current capability of the 20 A AC Input connector for the loudspeaker. When looping loudspeakers, consider the total current draw for all loudspeakers on the circuit, including the first loudspeaker.
· Make sure the AC power cable for the loudspeaker has the appropriate power plug (on the other end) for the area in which you will operate the loudspeaker. In addition, the AC power cable must be rated for the total current draw of all loudspeakers looped from the power source.
· Do not operate the unit if the power cable is frayed or broken.
· Keep all liquids away from USW-210P loudspeakers to avoid hazards from electrical shock.

CHAPTER 2: POWER REQUIREMENTS 15

USW-210P OPERATING INSTRUCTIONS 16

CHAPTER 3: AMPLIFICATION AND AUDIO CONNECTORS

The USW-210P drivers are powered by a proprietary 2-channel, open-loop, class D amplifier. The audio signal is processed with correction filters for flat phase and frequency responses, and by driver protection circuitry. Each channel has peak and rms limiters that prevent driver over-excursion and regulate voice coil temperatures. The USW-210P user panel (Figure 10) includes Input and Loop output connectors for audio, Limit and On/Status LEDs, and RMS connectors and controls (see Chapter 5, "RMS Remote Monitoring System").
Figure 10: USW-210P User Panel (Shown with Optional RMS Module)
AUDIO CONNECTORS
USW-210P is available with XLR 3-pin (Figure 11) connectors for audio Input and audio Loop output.

Audio Input (XLR 3-Pin Female)
The XLR 3-pin female Input connector accepts balanced audio signals with an input impedance of 10 k. The connector uses the following wiring scheme:
· Pin 1 -- 1 k to chassis and earth ground (ESD clamped)
· Pin 2 -- Signal (+)
· Pin 3 -- Signal ()
Pins 2 and 3 carry the input as a differential signal. Pin 1 is connected to earth through a 1 k, 1000 pF, 15 V clamped network. This circuitry provides virtual ground lift for audio frequencies while allowing unwanted signals to bleed to ground. Make sure to use balanced XLR audio cables with pins 13 connected on both ends. Telescopic grounding is not recommended and shorting an input connector pin to the case may cause a ground loop, resulting in hum.
TIP: If the loudspeaker produces unwanted noise or hiss, disconnect its input cable. If the noise stops, there is most likely nothing wrong with the loudspeaker. To locate the source of the noise, check the source audio, AC power, and electrical ground.
Audio Loop Output (XLR 3-Pin Male)
The XLR 3-pin male Loop output connector allows multiple loudspeakers to be looped from a single audio source. The Loop output connector uses the same wiring scheme as the Input connector. For applications that require multiple USW-210P, connect the Loop output of the first loudspeaker to the Input of the second loudspeaker and so forth.
NOTE: The Loop output connector is wired in parallel to the Input connector and transmits the unbuffered source signal even when the loudspeaker is powered off.

Figure 11: XLR 3-Pin Audio Connectors, Input and Loop Output

Calculating Load Impedance for Looped Audio Signals
To avoid distortion when looping multiple loudspeakers, make sure the source device can drive the total load impedance of the looped loudspeakers. In addition, the source device must be capable of delivering approximately

USW-210P OPERATING INSTRUCTIONS

20 dBV (10 V rms into 600 ) to yield the maximum SPL over the operating bandwidth of the loudspeakers.
To calculate the load impedance for the looped loudspeakers, divide 10 k (the input impedance for a single loudspeaker) by the number of looped loudspeakers. For example, the load impedance for 10 USW-210P is 1000 (10 k/ 10). To drive this number of looped loudspeakers, the source device should have an output impedance of 100 or less. This same rule applies when looping USW-210P with other Meyer Sound self-powered loudspeakers.

LF Limit LEDs
The low-frequency drivers for USW-210P are powered by separate amplifier channels, each with their own limiter. Limiting activity is indicated with two Limit LEDs on the user panel.

NOTE: Most source devices are capable of driving loads no less than 10 times their output impedance.
TIP: Audio outputs from Meyer Sound's loudspeaker GALAXY Network Platform have an output impedance of 50 ohms. Each output can drive up to 20 Meyer Sound (10 k) loudspeakers without distortion.
CAUTION: Make sure that all cabling for ! looped loudspeakers is wired correctly (Pin 1 to Pin 1, Pin 2 to Pin 2, and so forth) to prevent the polarity from being reversed. If one or more loudspeakers in a system have reversed polarity, frequency response and coverage will be significantly degraded.
TRUPOWER LIMITING
The USW-210P employs Meyer Sound's advanced TruPower® limiting. Conventional limiters assume a constant driver impedance and set the limiting threshold by measuring voltage alone. This method is inaccurate, because driver impedances change as frequency content in the source material changes, and as thermal values for the loudspeaker's voice coil and magnet vary. Consequently, conventional limiters often begin limiting prematurely, which reduces system headroom and dynamic range.
In contrast, TruPower limiting anticipates varying driver impedances by measuring both current and voltage to compute the actual power dissipation in the voice coil. This approach improves performance, both before and during limiting, by allowing the driver to produce the maximum SPL across its entire frequency range, while also retaining signal peaks. TruPower limiting also eliminates power compression at high levels over lengthy periods, which helps regulate voice coil temperatures, thereby extending the life of the driver.

Figure 12: USW-210P Limit LEDs
When engaged, the limiters not only protect the drivers but also prevent signal peaks from causing excessive distortion in the amplifier channels, thereby preserving headroom and maintaining smooth frequency response at high levels. When levels return to normal, below the limiter thresholds, limiting ceases.
USW-210P performs within its acoustical specifications at normal temperatures when the Limit LEDs are unlit, or when the LEDs are lit for 2 seconds or less and then turn off for at least 1 second. If the LEDs remain lit for longer than 3 seconds, the loudspeaker enters hard limiting where:
· Increases to the input level have no effect
· Distortion increases due to clipping
· Drivers are subjected to excessive heat and excursion, thereby compromising their lifespan
CAUTION: The Limit LEDs indicate when a ! safe, optimum level is exceeded. If an USW-210P loudspeaker system begins to limit before reaching the desired SPL, consider adding more units to the system.
AMPLIFIER COOLING SYSTEM
The USW-210P loudspeaker is convection cooled. The amplifier's heat sink provides natural convection cooling from the air flowing near its fins.
CAUTION: The USW-210P heat sink can reach ! very high temperatures during extreme operation. Wait 15 minutes for the unit to cool before touching.

ON/STATUS LED
During normal operation, when USW-210P is powered on, the On/Status LED is solid green. If the loudspeaker encounters a hardware fault, or the unit begins to overheat, the LED flashes red. In some instances, the loudspeaker will continue to output audio while the LED flashes red, though with a reduction in the limiter threshold and acoustic output to protect the loudspeaker.
If a loudspeaker is overheating (for RMS-equipped loudspeakers, you can verify this situation in Compass RMS), a reduction in SPL may be necessary. If after a reduction in SPL and an appropriate cooling period the On/Status LED continues to flash red (does not return to solid green), contact Meyer Sound Technical Support.
If the On/Status LED flashes red and the loudspeaker does not output audio, contact Meyer Sound Technical Support immediately.
CAUTION: If an USW-210P loudspeaker system ! consistently overheats before reaching the desired SPL, consider adding more units to the system.
NOTE: During startup, the On/Status LED flashes multiple colors successively. For more information about the power on sequence, see "Intelligent AC Power Supply" on page 14.
TIP: When an USW-210P is connected to an RMS network, the Compass RMS software provides additional feedback about the loudspeaker's hardware status and operating temperature. For more information, see Chapter 5, "RMS Remote Monitoring System."

CHAPTER 5: RMS REMOTE MONITORING SYSTEM

The USW-210P loudspeaker optionally includes an RMS remote monitoring system module, allowing it to be connected to an RMS network. RMS reports, in real time, the status and power usage of multiple Meyer Sound loudspeakers from a Mac or Windows-based computer. The RMServer communicates with Meyer Sound loudspeakers equipped with RMS modules. RMServer is a compact, Ethernet-based hardware unit with two FT-10 RMS data ports. RMServer stores system configurations internally, eliminating most manual data entry. Systems can be monitored from a computer at front-of-house or backstage, or from a laptop anywhere within the venue over WiFi.
NOTE: For the latest RMS system requirements, visit meyersound.com).

loudspeaker can be identified in Compass RMS by pressing the Identify button on the loudspeaker's RMS module.
Loudspeaker icons can be arranged in Compass RMS and saved as pages to represent how the loudspeakers have been deployed in the system. Multiple pages can be saved and recalled for specific performances and venues.
RMS MODULE
The USW-210P RMS user panel (Figure 22) includes an Identify button, Remote Mute switch, Wink/Activity LED, and two Network connectors.

NOTE: RMS does not control AC power.

COMPASS RMS SOFTWARE
Compass RMSTM software provides extensive system status and performance data for each loudspeaker, including amplifier voltage, limiting activity, power output, fan and driver status, as well as mute and solo capability. Loudspeakers are added to the RMS network and assigned a node name during a one-time discovery procedure. Once loudspeakers are identified on the RMS network, they appear in Compass RMS as icons that can be customized to suit your needs (Figure 21).

Figure 22: USW-210PRMS Module
NOTE: The Identify button and Wink/Activity LED on the RMS user panel are used exclusively by RMS and have no effect on the acoustical or electrical activity of the loudspeaker.

Figure 21: Compass RMS Window
Individual loudspeakers can be physically identified with the Wink option in RMS, which lights the Wink LED on the RMS module of that particular loudspeaker. Conversely, a

Identify Button
The Identify button serves the following functions:
· If the loudspeaker has not yet been discovered on the RMS network (Wink/Activity LED not lit), press the Identify button to discover it.
· To remove the loudspeaker from the RMS network, press and hold the Identify button during startup (see "Resetting the RMS Module" on page 26).
· To wink a discovered loudspeaker, press the Identify button. The Wink LED on the loudspeaker icon in Compass RMS lights up and the Wink/Activity LED on the loudspeaker's RMS user panel turns solid green. Press the Identify button again to unwink the loudspeaker.

USW-210P OPERATING INSTRUCTIONS

TIP: The loudspeaker can also be winked by clicking the Wink button on the loudspeaker icon in Compass RMS.
Wink/Activity LED (Green)
The green Wink/Activity LED indicates the status of the loudspeaker:
· During startup, the LED flashes green 10 times.
· If the loudspeaker has not yet been discovered on the RMS network, the LED is not lit after startup.
· If the loudspeaker has been successfully discovered on the RMS network, the LED flashes green continuously and flashes more rapidly with increased data activity.
· When the loudspeaker is winked, either by clicking the Wink button in Compass RMS or by pressing the Identify button on the RMS user panel, the LED is solid green. The LED remains solid green until the loudspeaker is unwinked.

RMS Network Connectors
The Weidmuller 2-conductor, locking connectors transfer data to and from the RMS network. Two connectors are provided to allow for easy connection of multiple (daisy-chained) loudspeakers on the network. Included with each RMS-equipped loudspeaker are RMS cable connectors and mounting blocks for constructing RMS cables. The mounting blocks allow the Weidmuller connectors to be securely attached to the RMS module with screws.
NEURON ID FOR RMS MODULE
Each RMS module has a unique 12-character Neuron ID (NID) that identifies the loudspeaker on the network. The NID is automatically detected by RMServer but can also be entered manually, if necessary, when configuring RMS systems in Compass RMS without loudspeakers present. The NID label is located on the RMS user panel near the orange Network connectors.

TIP: The Wink function is useful for identifying the physical loudspeaker corresponding to a loudspeaker icon in Compass RMS.
Remote Mute Switch
The recessed Remote Mute switch on the USW-210P RMS module (Figure 23) determines whether Compass RMS can control muting and soloing of the loudspeaker. The USW-210P ships from the factory with the switch enabled.

RESETTING THE RMS MODULE
You can use the Identify button to reset the USW-210P RMS module when powering on the loudspeaker. This action will cause the module to be removed from the RMS network.
To reset the RMS module:
1. Power down the loudspeaker.
2. Press and hold the Identify button.
3. While continuing to hold down the Identify button, power on the loudspeaker.
4. After the Wink/Status LED flashes on and off, release the Identify button. The RMS module is reset and the loudspeaker is removed from the RMS network.

Figure 23: Remote Mute Switch
· Disable: When the Remote Mute switch is set to Disable (to the left), the loudspeaker cannot be muted or soloed from Compass RMS.
· Enable: When the Remote Mute switch is set to Enable (to the right), the loudspeaker can be muted and soloed from Compass RMS.
NOTE: Compass RMS has a preference that can be set to disable Mute and Solo functions, eliminating any possibility of accidentally muting loudspeakers.

CHAPTER 6: SYSTEM DESIGN AND INTEGRATION TOOLS

This chapter introduces MAPP, Meyer Sound's patented system design tool and the Galileo GALAXY Network Platform.
MAPP SYSTEM DESIGN TOOL
The MAPP System Design Tool (Figure 24) is a powerful, cross-platform application for accurately predicting the coverage pattern, frequency response, phase response, impulse response, and SPL capability of individual or arrayed Meyer Sound loudspeakers.

MAPP software allows for configuration of Meyer Sound loudspeaker systems and definition of the environment in which they operate, including air temperature, pressure, humidity, and the location of prediction surfaces. Importing both CAD (.DXF) and Sketchup (.SKP) files containing detailed venue information to act as an anchor model to the prediction surfaces and a visual aid to facilitate prediction data interpretation is also possible.
TIP: See meyersound.com for support and more information about MAPP.

Figure 24: MAPP System Design Tool
Whether planning for fixed installations or for tours with multiple venues, use MAPP to accurately predict the appropriate loudspeaker deployment for each job, complete with coverage data, system delay and equalization settings, rigging information, and detailed design illustrations. MAPP's accurate, high-resolution predictions ensure that systems will perform as intended, thereby eliminating unexpected coverage problems and minimizing onsite adjustments.
The key to the accuracy of MAPP's predictions is Meyer Sound's exhaustive database of loudspeaker measurements. Performance predictions for each loudspeaker are based on 3-dimensional, 65,000+ 1/48th-octave-band measurements taken in the Meyer Sound anechoic chamber. The extraordinary consistency between Meyer Sound loudspeakers guarantees that predictions from MAPP will closely match their actual performance.

MAPP Capabilities
With MAPP, the user can:
· Simulate different loudspeaker configurations to refine system designs and determine the best coverage for intended audience areas
· Model loudspeaker interactions to locate constructive and destructive interferences so that loudspeakers can be re-aimed and repositioned as necessary
· Place microphones anywhere in the Model View space and predict loudspeaker frequency response, phase response, and sound pressure levels at each microphone position
· Determine delay settings for fill loudspeakers using the Inverse Fast Fourier Transform and phase response feature
· Preview the results of signal processing to determine optimum settings for the best system response
· Automatically calculate load information for arrays to determine necessary minimum rigging capacity, front-to-back weight distribution, and center of gravity location
· Generate and export system images and system PDF reports for client presentations
· Synchronize GALAXY processor output channel settings in real time with virtual or real GALAXY units, allowing in-the-field changes to be predicted during system alignments.

USW-210P OPERATING INSTRUCTIONS
GALILEO GALAXY NETWORK PLATFORM
The Galileo GALAXY Network Platform is a sophisticated loudspeaker management tool for controlling all Meyer Sound speaker types. The GALAXY loudspeaker processor extends a high level of audio control in driving and aligning loudspeaker systems with multiple zones. It provides a powerful tool set for corrective equalization (EQ) and creative fine-tuning for a full range of applications from touring to cinema. Users can readily program the GALAXY processor using Compass software running on a host computer or via the Compass Go application for the iPad. Connecting MAPP to the GALAXY processor will also allow the user to push output channel settings created in MAPP as a starting point. Compass Control Software includes custom-designed settings for each family of speakers, as well as to integrate families together. For example, the Product Integration feature matches the phase characteristics between Meyer speaker families to ensure the most coherent summation. Processing tools for inputs and outputs include delay, parametric EQ and U-Shaping EQ. Output processing also includes polarity reversal, Low-Mid Beam Control (LMBC), atmospheric correction, and All Pass filters. The built-in summing and delay matrices allow a user to easily assign gain and delay values, respectively, at each cross point. This capability greatly facilitates using one loudspeaker to satisfy multiple purposes. Front panel controls let a user intuitively and quickly operate a GALAXY processor without a computer during live use. The GALAXY 408, GALAXY 816 and GALAXY 816-AES3 processor versions have the same audio processing capability with different I/O. See www.meyersound.com to locate their datasheets for more information.

APPENDIX A: MEYER SOUND WEATHER PROTECTION

The Weather Protection option from Meyer Sound is intended to increase the useful life of Meyer Sound loudspeakers when they are installed outdoors and exposed to different and often harsh weather conditions. Meyer Sound Weather Protection includes a penetrating treatment to raw wood, use of special primers, and plating on all steel parts used (or alternatively, the use of stainless steel hardware). Weather Protection is designed to prevent malfunctions caused by harsh operating environments and slows the accelerated wear and tear that occurs in outdoor environments.
When Is Weather Protection Advisable?
Weather Protection is strongly recommended for all permanent outdoor installations where loudspeakers are directly exposed to the elements. This recommendation includes desert and semi-arid climates, where protection against dust and sand is important, and where infrequent rainstorms can contribute to deterioration of loudspeaker components.
Weather Protection is also recommended when the loudspeakers are sheltered from direct exposure to precipitation but are nevertheless exposed to prolonged high humidity, fog or mist. Examples would be installations on covered outdoor terraces or pavilions.
Weather Protection is further advisable for portable or touring systems when any significant outdoor use is anticipated. Even though standard procedures may call for using external protective measures, these are often not implemented in time to prevent moisture intrusions that could lead to premature performance degradation of the loudspeaker.
Climate Variation and Owner Maintenance
The wear and tear on a loudspeaker will vary significantly with different climatic conditions. For example, a weather-protected loudspeaker installed in a sunlight-exposed location on an ocean pier will experience much harsher conditions than a loudspeaker in a similar installation that is shaded by trees and exposed only to rainfall. The constant exposure to direct UV radiation and a salt air environment will cause a loudspeaker to wear more quickly than one with partial UV shielding and exposed only to freshwater moisture.
Wear can eventually affect the performance of the loudspeaker. It also affects aesthetics. For example, in salt

air environments, the exterior grille can quickly show signs of oxidation, causing unsightly discoloration.
Apart from selecting suitable weather protection, the progress of wear and tear on the loudspeaker can be slowed by a regular schedule of inspection and cleaning. This maintenance is particularly necessary in harsh environments. Inspection and cleaning should include routine removal of any visible oxidation or environmental particulates, as these can accelerate metal corrosion or decay of the cabinet. If installed loudspeakers are not in use for an extended period, exterior protection or temporary removal and storage of the loudspeakers should be considered.
Benefits of Weather Protection
There are several benefits to selecting the Meyer Sound Weather Protection option:
Functionality--Weather Protection prolongs the service life of the loudspeaker by preventing premature degradation of internal components.
Safety--Weather Protection lessens the chance of electrical malfunctions or structural failures.
WARNING: IT IS THE RESPONSIBILITY OF
! PURCHASERS/USERS/OPERATORS TO
SELECT WEATHER PROTECTION WHEN APPROPRIATE FOR THEIR USE AND TO PERIODICALLY INSPECT THEIR LOUDSPEAKER INSTALLATIONS FOR ANY DETERIORATION THAT MAY LEAD TO SAFETY CONCERNS.
Aesthetics--Weather Protection slows wear and tear on the exterior of the loudspeaker in harsh conditions. Early signs of wear and tear on the exterior of the loudspeaker indicate over-exposure to the elements.
Standards Compliance--Weather Protection helps in meeting IP ratings for loudspeakers. IP ratings are an internationally recognized standard often used in installations involving our products. A further explanation of IP ratings is given in the "IP Ratings" Section on page 31.

USW-210P OPERATING INSTRUCTIONS

WEATHER PROTECTION COMPONENTS
Standard Weather Protection
Meyer Sound designs toward an IP rating of IPX4 (see "IP Ratings" on page 31) for Standard Weather Protection, which includes the following components:
· Wood treatment--Prior to cabinet manufacturing, the raw wood receives a special treatment that penetrates and stabilizes the wood fibers to withstand a wide range of temperatures and exposure to extreme humidity.
· Cabinet finishing--The assembled cabinets receive a highly impervious finish that includes a sealing primer and a finishing topcoat. The coatings are applied on both surfaces, with one coat on the interior and two on the exterior. The final step is a two-part modified acrylic urethane similar to that used in military applications.
· Driver treatment--All cone drivers are coated with a water-resistant sealant.
· Exterior protection--Grille frames are coated to resist corrosion, and all components that mount to the cabinet use custom gaskets and stainless steel fasteners.
· Removable rain hood--The rain hood is designed to shield connectors even in wind-driven rain.

modifies a Meyer Sound supplied rigging component to support their installation method, it is considered compromised and out of warranty.
· All loudspeaker cabling must be installed with a "drip-loop" or equivalent method to ensure that rain or water is NOT wicked toward the loudspeaker.
If in doubt about an installation method, contact Meyer Sound Technical Support for assistance.
Always discuss the environmental conditions of your Meyer Sound installation with your Sales Manager, and verify the availability of Weather Protection for your selected loudspeaker models. The Sales Manager, together with Technical Support, will verify the appropriate level of weather protection for the loudspeakers and related rigging hardware.

INSTALLATION PRACTICES
Meyer Sound assumes normal and accepted installation practices are used when installing Meyer Sound Loudspeakers outdoors. Deviation from such practices may cause weather protection to be ineffective and void the warranty for the loudspeaker.
Examples of unacceptable and acceptable installation practices include:
· Loudspeakers installed outdoors should not face upward.
· Loudspeakers with a rain hood should be installed in such a way that the rain hood opening is not facing any direction but down.
· Meyer Sound-supplied rigging components should not be modified (for example, by drilling additional holes in a MUB for mounting to a wall). When an installer/integrator

IP RATINGS
IP stands for "Ingress Protection." The current format for expressing an IP rating is a 2-digit code. The first digit of an IP rating represents protection from solid objects. The second digit of an IP rating represents protection from water or moisture. Table 5 provides a chart of IP ratings and the corresponding definitions of the rating.
NOTE: IP ratings only apply to the "ENCLOSURE." A loudspeaker is considered an enclosure and as such an IP rating can be applied to it. Rigging hardware is not an enclosure and therefore IP ratings do not apply. Also, cable and cable-mount connectors used to connect to the loudspeaker are NOT part of the enclosure and therefore not part of the IP rating. Only the chassis-mounted part of the connector is considered part of the enclosure.

APPENDIX B: RAIN HOOD
Weather-protected USW-210P loudspeakers include a rain hood for indoor/outdoor touring and sheltered outdoor installations.
CAUTION: There is only one proper loudspeaker orientation once the rain hood is installed--horizontal with
! the cables exiting at the bottom. With any other orientation, there is a potential for water to intrude into the
cabinet. Never place the cabinet in a vertical position in outdoor applications.
RIGID RAIN HOOD
The USW-210P rigid removable rain hood is easily attached and removed with the included four screws (Figure 25).
Figure 25: USW-210P with rigid rain hood (left) and interior cable routing illustration (right)
To attach the USW-210P rigid rain hood: 1. Attach any required cables to the USW-210P loudspeaker. 2. Carefully route the cables, so that they wrap over and down the inner rainhood wall. 3. Attach the rain hood to the user panel, and secure it to the center of the panel with its four 6-32 x 0.38-inch screws. 4. Make sure to tighten the screws to create a good seal against the user panel. The recommended torque value for the
screws is 1012 in-lb (1.11.4 N-m). CAUTION: The weather-protected USW-210P must be mounted with a 0° tilt, or preferably with a slight
! down-tilt. This angle shields the driver from the elements and does not allow water to accumulate. Do not tilt
the cabinet up, as the drivers and cabinet will accumulate water. CAUTION: Weather-protected units using the rigid rain hood are rated IPX4 for water intrusion.
