THE MM-4XP MINIATURE LOUDSPEAKER The MM-4XP miniature loudspeaker is a self-powered loudspeaker designed for high-quality distributed systems. Housed in a compact aluminum enclosure, the MM-4XP is especially suitable for installations involving space limitations and visibility concerns. The loudspeaker's proprietary 4-inch cone transducer, manufactured at Meyer Sound's Berkeley factory, delivers a linear peak SPL of 111.5 dB with crest factor > 16.5 dB (see "Specifications" on page 9), and has a wide operating frequency range of 120 Hz to 18 kHz with very low distortion. The MM-4XP exhibits the same high intelligibility and flat frequency and phase responses for which Meyer Sound loudspeakers are known. Peak and rms limiters regulate loudspeaker temperatures and excursion, ensuring that the MM-4XP performs exceedingly well even when driven into overload. Information and specifications are subject to change. Updates and supplementary information are available at: · meyersound.com/products · meyersound.com/documents. Meyer Sound Technical Support is available at: · +1 510 486.1166 (Monday through Friday 9:00 am to 5:00 pm PST) · +1 510 486.0657 (after hours support) · meyersound.com/support. MM-4XP Loudspeaker The MM-4XP's amplifier and signal-processing circuits are designed to store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and long cable runs. The MM-4XP receives balanced audio and DC power from a SwitchCraft® EN3TM 5-pin male connector on its rear panel. 1 MM-4XP OPERATING INSTRUCTIONS MM-4XP loudspeaker systems require an Meyer Sound external power supply (see meyersound.com/product/mps for more information and to locate datasheets and operating instructions). The MPS-488HP single-space 19-inch rack unit receives eight channels of balanced audio from its XLR female inputs and routes the audio, along with 48 V of DC power, to its eight channel outputs. The outputs--equipped with either Phoenix 5-pin male connectors on the MPS-488HPP model, or EN3 5-pin female connectors on the MPS-488HPE model--can deliver DC power to the MM-4XP loudspeakers at cable lengths of up to 300 feet with just 1 dB of loss in peak SPL using 18 AWG wire. The use of composite multiconductor cables (such as Belden® 1502) allows a single cable to carry both audio and DC power to the MM-4XP. Longer cable lengths are possible for moderate applications that don't drive the loudspeakers to maximum output, or for installations with heavier wire gauges. The smaller MPS-482HP provides two channel outputs via 5-pin male Phoenix connectors. MPS-488HPP Power Supply The MM-4XP's extruded aluminum enclosure acts as a heat sink to dissipate heat from the driver's voice coil. The enclosure is available in standard white or black anodized finishes with a perforated steel grille. It can also be custom painted to match specific color schemes. The MUB-MM-4XP U-bracket mounts the loudspeaker on walls and ceilings at adjustable angles. The U-bracket is also available in standard white or black anodized finishes and custom colors. MM-4XP Loudspeaker Mounted with MUB-MM-4XP U-Bracket 2 THE MM-4XP LOUDSPEAKER THE MM-4XP CONNECTOR The MM-4XP receives DC power and balanced audio from a EN3 5-pin male connector on its rear panel. The connector's five pins include two for DC power (negative and positive) and three for balanced audio (shield, negative, and positive). To function properly, the MM-4XP requires 48 V of DC power. should be used for DC power. The blue, white, and shield wires should be used for audio.

MM-4XP Connector A single composite cable (such as Belden 1502) wired for both DC power and balanced audio can be used to connect the MM-4XP to one of the MPS-488's eight or the MPS482's two channel outputs. Table 1: MM-4XP Cable Wiring for Belden 1502 Wire Gauge Signal Red 18 AWG DC power, positive (+) Black 18 AWG DC power, negative () White 22 AWG Balanced audio, positive (+) Blue 22 AWG Balanced audio, negative () Shield 24 AWG Balanced audio, shield Wiring the EN3-to-Pigtail Cables Each MM-4XP loudspeaker comes with one EN3 5-pin female to pigtail cable. The EN3 end of the cable connects directly to the MM-4XP connector. The pigtail end of the cable can be equipped with either an EN3 5-pin male connector for connecting to the MPS-488HPE power supply, or a Phoenix 5-pin female connector for connecting to the MPS-488HPP or MPS-482HP power supplies. The pigtail can also be spliced to a longer loudspeaker cable or to a junction box. The included EN3-to-pigtail cable uses Belden 1502 cable, which can be wired for both DC power and balanced audio. The EN3-to-pigtail cable is available in plenum or regular (non-plenum) versions. NOTE: For a complete list of cables and cable connectors available from Meyer Sound that can be used with the MM-4XP loudspeaker, see "MM-4XP Accessories" on page 15. When assembling MM-4XP loudspeaker cables with the included EN3-to-pigtail cables, make sure to use the wiring scheme in Table 1. The red and black wires in Belden 1502 cable have a thicker gauge than the other three wires and When wiring MM-4XP cables, it is extremely important that each pin in the cable be wired so that the pins in the MM-4XP connector align with those in the MPS channel output connector (see "Channel Outputs" on page 6). Make sure the 48 V DC from the MPS power supply is wired directly (and only) to the 48 V DC pins on the MM-4XP connector, and that the polarity is observed (negative to negative, positive to positive) to avoid damage to the loudspeaker. In addition, make sure the audio pins are wired correctly; polarity reversals for audio signals can affect system performance. NOTE: For information on MM-4XP cable requirements, see "MM-4XP Current Draw and Cable Requirements" on page 3. MM-4XP Current Draw and Cable Requirements Each MM-4XP loudspeaker draws a maximum current of 0.7 A rms and 2.2 A peak from the 48 V DC output of the MPS power supply. The current draw for the MM-4XP is dynamic and fluctuates as operating levels change. The cabling between the MM-4XP and the MPS power supply 3 MM-4XP OPERATING INSTRUCTIONS adds resistance and hence causes a voltage drop at the loudspeaker. Because lower voltages compromise peak SPL, and in some cases frequency response, cable resistance should be minimized. NOTE: When connecting an MM-4XP to an MPS channel output, the total cable resistance should not exceed 4 ohms. Cable Lengths and Cable Gauges for MM-4XPs When connecting an MM-4XP to an MPS channel output, you can use cable lengths of up to 300 feet with only 1 dB of peak SPL loss using 18 AWG wire. Longer cable lengths are possible with heavier wire gauges (see Table 2 and Table 3). NOTE: For music playback at moderate levels (when the MM-4XP is not driven to maximum output), cable lengths of up to 500 feet with 18 AWG wire are acceptable. Table 2: MM-4XP Loudspeaker Cable Lengths (AWG) Cable Gauge Resistance (/ft) Approximate Max.

NOTE: For long cable runs, you can use large cable gauges for most of the run and then terminate with the included EN3-to-pigtail cable. THE MM-4XP LED The MM-4XP has a three-color LED on its rear panel that changes color to indicate the loudspeaker's status. Powering On (Green) When powering up the MM-4XP loudspeaker, the following startup events occur and are indicated by the LED: 1. The LED flashes green and then yellow during power up. 2. The LED turns solid green indicating the loudspeaker is ready to reproduce audio. CAUTION: If the MM-4XP LED turns red and stays solid red after powering up and the audio is muted, the loudspeaker has encountered a failure and may need to be serviced. Contact Meyer Sound Technical Support. CAUTION: If the MM-4XP LED turns solid red and the loudspeaker continues to output audio, though at reduced levels, the loudspeaker's voltage may have dropped below 25 V DC. Operation of the loudspeaker under these conditions is not recommended and the loudspeaker's power supply and cabling should be verified. Limiting (Yellow) Limiting activity is indicated when the MM-4XP LED turns yellow. When engaged, the limiter protects the loudspeaker's driver and prevents signal peaks from causing excessive distortion in the loudspeaker's amplifier, thereby preserving headroom and maintaining smooth frequency response at high levels. When the level returns to 4 normal, below the limiter's threshold, the LED turns green and limiting ceases. The MM-4XP performs within its acoustical specifications at normal temperatures when the MM-4XP LED is green, or if the LED turns yellow for two seconds or less and then turns green for at least one second. If the LED remains yellow for longer than three seconds, that loudspeaker enters hard limiting where: · Increases to the input level have no effect. · Distortion increases due to clipping and nonlinear driver operation. · The driver is subjected to excessive heat and excursion, which will compromise its life span and may eventually lead to damage over time. CAUTION: The MM-4XP LED turns yellow when the loudspeaker's signal goes 2 dB beyond the actual onset of limiting, and indicates a safe, optimum level has been exceeded. If the MM-4XP loudspeakers in a system begin to limit before reaching the required SPL, consider adding more loudspeakers to the system to achieve the desired SPL without exposing the loudspeakers to excessive levels and possible overheating. Loudspeaker Temperature and Limiting The MM-4XP LED turns solid yellow when the temperature of the MM-4XP heatsink reaches 65° C (145° F), indicating the unit is reaching its maximum heat dissipation and a reduction in SPL is recommended. While the MM-4XP will continue to operate while the LED is yellow, the limiter threshold is lowered to a safe level (causing the output level to be lowered by 6 dB) to prevent the loudspeaker from overheating. When the temperature of the MM-4XP heatsink cools to 50 °C (122 °F), the LED changes from yellow to green and the limiter threshold returns to normal. Clipping (Red) The MM-4XP LED flashes red when its input signal causes the amplifier to overload. If the LED flashes red continuously, the loudspeaker is severely overloaded and a reduction in the input level is recommended. CAUTION: If the MM-4XP LED turns solid red and the loudspeaker continues to output audio, though at reduced levels, the loudspeaker's voltage may have dropped below 25 V DC. Operation of the loudspeaker under these conditions is not THE MM-4XP LOUDSPEAKER recommended and the loudspeaker's power supply and cabling should be verified. 5 MM-4XP OPERATING INSTRUCTIONS CONNECTING MM-4XP LOUDSPEAKERS TO A MEYER SOUND POWER SUPPLY To connect MM-4XP loudspeakers to an MPS power supply: 1. Power off the MPS power supply. 2. Connect audio sources (from a mixer or processor) to the MPS channel inputs. Use balanced XLR cables. 3. Use the MPS link switches to route channel inputs to the desired channel outputs. 4. Connect the MM-4XP loudspeakers to the MPS channel outputs. Use a composite cable (such as Belden 1502) wired for both DC power and balanced audio and outfitted with the appropriate connector: · For an MPS-488HPP or MPS-482HP power supply, use an EN3 5-pin female to Phoenix 5-pin female cable. CAUTION: Make sure the MM-4XP loudspeaker cables are wired correctly. For details on assembling loudspeaker cables, see "Assembling Loudspeaker Cables" on page 17. 5. Power on the MPS power supply and monitor the LEDs on the front panel to verify connections (for more information, see "Voltage and Load Current LEDs (18)" on page 3). 6. Check the MM-4XP LEDs on the rear panel and verify they are green (ready to reproduce audio). 7. Enable output from the audio sources (from the mixer or processor) connected to the MPS power supply. · For an MPS-488HPE power supply, use an EN3 5-pin female to EN3 5-pin male cable. · To join two cables, one with an EN3 5-pin male cable mount connector to one with an EN3 5-pin female cable mount connector, use an EN3 5-pin female-to-male cable coupler (PN 28.163.033.01). Cable 6 MOUNTING THE MM-4XP IMPORTANT SAFETY CONSIDERATIONS When installing Meyer Sound loudspeakers, the following precautions should always be observed: · All Meyer Sound products must be used in accordance with local, state, federal, and industry regulations. It is the owner's and user's responsibility to evaluate the reliability of any rigging method for their application. Rigging should only be carried out by experienced professionals. · Use mounting and rigging hardware that has been rated to meet or exceed the weight being hung. · Make sure to attach mounting hardware to the building's structural components (studs or joists), and not just to the wall surface. Verify that the building's structure and the anchors used for the installation will safely support the total weight of the mounted loudspeakers. · Use mounting hardware appropriate for the surface where the loudspeaker will be installed. · Make sure bolts and eyebolts are tightened securely. Meyer Sound recommends using Loctite® on eyebolt threads and safety cables. · Inspect mounting and rigging hardware regularly. Immediately replace any worn or damaged components. 2. Insert the MM-4XP into the U-bracket, seating its sides against the bracket's attached neoprene strips. Align the loudspeaker's screw inserts near the top of the U-bracket's slots to allow for maximum tilting. 3. Secure the loudspeaker to the U-bracket using the two 3/8-inch-16 screws and two shoulder washers included with the MUB-MM-4XP. The shoulder washers should be placed between the screws and the outside of the U-bracket, with the shoulder oriented toward the loudspeaker. Do not yet tighten the U-bracket screws. MOUNTING THE MM-4XP WITH THE MUB-MM4XP U-BRACKET The MUB-MM-4XP U-bracket allows the MM-4XP to be mounted on virtually any flat surface at adjustable angles. (See "MUB-MM-4XP Dimensions" on page 14 for size.) To mount the MM-4XP with the MUB-MM-4XP U-bracket: 1. Mount the MUB-MM-4XP U-bracket to the mounting surface using screws in the two holes in the back of the U-bracket. Use fastening hardware appropriate for the mounting surface. CAUTION: Make sure to use the shoulder washers. They insulate the MM-4XP from the U-bracket and mounting surface, eliminating grounding and differential problems. 4. Adjust the angle of the loudspeaker as desired. 5. Tighten the U-bracket screws to secure the MM-4XP. 7 MM-4XP OPERATING INSTRUCTIONS 8 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 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. 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. 9 MM-4XP 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.

Loudspeaker SPL compression measured with M-noise at the onset of limiting, 2-hour duration, and 50 °C ambient temperature is < 2 dB. M-noise is a full bandwidth (10 Hz22.5 kHz) test signal developed by Meyer Sound to better measure the loudspeaker's music performance. It has a constant instantaneous peak level in octave bands, a crest factor that increases with frequency, and a full bandwidth Peak to RMS ratio of 18 dB. The presence of a greater-than (>) symbol with regard to crest factor indicates it may be higher depending on EQ and boundary loading. Pink noise is a full bandwidth test signal with Peak to RMS ratio of 12.5 dB. B-noise is a Meyer Sound test signal used to ensure measurements reflect system behavior when reproducing the most common input spectrum, and to verify there is still headroom over pink noise.

Make sure that the 48 V DC from the external power supply is wired directly (and only) to the 48 V DC pins on the loudspeaker connector, and that the polarity is observed (negative to negative, positive to positive) to avoid damage to the loudspeaker. In addition, make sure that audio pins are wired correctly; polarity reversals for audio signals affect system performance. ASSEMBLING PHOENIX-TO-EN3 LOUDSPEAKER CABLES When connecting loudspeakers equipped with EN3 connectors to power supplies equipped with Phoenix connectors, a Phoenix 5-pin female to EN3 5-pin female cable is required. The following procedure documents how to assemble this cable. If starting with an EN3-to-pigtail cable, skip steps 47 in this procedure. Assembled Phoenix-to-EN3 Cable To assemble a Phoenix-to-EN3 cable: 1. If the cable has not yet been stripped, strip one end of the cable. Strip the outer shielding by 1 inch and then strip the black, red, blue, and white wires by 0.275 inch. 1 inch 0.275 inch 2. Insert the five exposed conductors into the five cable holes in a Phoenix 5-pin female cable mount connector. Use the following wiring scheme.
