Section 2: Understanding the Difference

2.1 The Synergy Horn

The Synergy Horn successfully couples the radiation from multiple drivers into a single horn to yield the effective performance of a single horn/driver system with high sensitivity, excellent directivity control, and a wide frequency response.

Section 3: Initial Set Up

3.1 What Size Amplifier to Use

Selecting the right amplifier for your loudspeaker depends on a variety of factors and uses. The owner is ultimately responsible for choosing the best amplifier or amplifiers for the application. It is recommended to choose an amp that is rated between the continuous and program ratings. Note that "Continuous" does not mean "forever." Most loudspeaker manufacturers, including Danley Sound Labs, subscribe to the AES standards for loudspeaker power ratings.

3.2 Connecting to the Synergy Horn

Danley loudspeakers feature two NL4 ("speak-on") connectors on the rear panel. With the exception of the SH96HO, SH46, and SM80M, all SM and SH series loudspeakers are wired as passive. The NL4 connectors are wired in parallel.

Pinout: Passive

• 1+: Positive Full Range
• 1-: Negative Full Range
• 2+: Pass Through
• 2-: Pass Through

Pinout: Bi-amp

• 1+: Positive LF
• 1-: Negative LF
• 2+: Positive Mid/High
• 2-: Negative Mid/High

NL4 Connector Wiring Diagram Description: A diagram illustrating the wiring of an NL4 connector. It shows pin assignments for both passive and bi-amp configurations. For passive mode, pins 1+ and 1- are used for the full-range signal. For bi-amp mode, pins 1+ and 1- are for the low-frequency (LF) channel, and pins 2+ and 2- are for the high/mid-frequency channel. The diagram also indicates a crossover component and drivers.

3.3 Switch Modes for SH96HO, SH46 and SM80M

The SH96HO, SH46, and SM80M can operate in two modes: Bi-amp or passive. In passive mode, the connection is to pins +1 and -1. In Bi-amp mode, connect the low-frequency amplifier channel to pins 1+ and 1- of the NL4, and the high/mid channel to pins 2+ and 2-. Additionally, the four 15-inch woofers on the SH96HO can be switched to present a 2 or 8 ohm load.

Passive Mode Operation:

In the "Passive" setting, an internal passive crossover is utilized. Using a SH96HO in passive mode is considered a compromise. In the passive/8 ohm mode, the low-end output will be significantly lower. This can be acceptable in larger clusters where multiple woofers provide coupling. It is also useful for very long speaker runs or when the amplifier cannot deliver sufficient power into 2 ohms. For more low-end output in passive mode, use the 2 ohm setting.

Bi-amp Mode Operation:

The BIAMP setting allows the SH96HO to achieve its full potential as a high-output device. In BIAMP mode, no crossover is applied to the four 15-inch drivers. It is strongly advised to use a crossover set to a high pass of 40 Hz at 24 dB Butterworth for the low-frequency section and 600 Hz at 12 dB Butterworth. The high/mid section should be high-passed at 400 Hz at 24 dB Butterworth. In BIAMP mode, you can also select between a 2 ohm load and an 8 ohm load for the woofers. CAUTION: If selecting the 2 ohm setting, ensure the chosen amplifier can accommodate 2 ohm loads. Remember that when running a 2 ohm load, the resistance of the speaker cable becomes significant; use the largest gauge and shortest run possible.

Speaker Mode Wiring Diagrams Description: Three diagrams illustrate speaker connections. One shows "PASSIVE MODE" with connections to pins 1+ and 1-. Another shows "SH96HO BIAMP MODE" with connections to pins 1+ and 1- for drivers and pins 2+ and 2- to mid/high drivers, featuring a 2ohm/8ohm switch. A third diagram shows "SH46 BIAMP MODE" with similar connections.

3.4 Impedance

On the SH96HO, in active mode, the impedance of the low-frequency section is selected by a toggle switch, offering either 2 ohms or 8 ohms. The mid/high section has an impedance of 4 ohms. By convention, the impedance of a loudspeaker is taken from the lowest point. In the passive setting with the woofers switched to 8 ohms, the SH96HO presents a nominal 4 Ohm load. With the woofers switched to 2 Ohms, in passive mode, the SH96HO presents a nominal 2 Ohm load.

3.5 Rigging

Statement: "If you have to ask how, you probably shouldn't be doing it!"

Safety Precautions for Rigging

Before attempting to rig or suspend Danley speakers, read and understand the following safety information.

IMPORTANT RIGGING SAFETY WARNING!

The information in this section is assembled from recognized engineering data and is intended for informational purposes only. None of this information should be used without first obtaining competent advice with respect to applicability to a given circumstance. Danley Sound Labs does not provide representation or warranty on this information. Anyone making use of this information assumes all liability arising from such use.

All information presented herein is based upon materials and practices common to North America and may not directly apply to other countries due to differing material dimensions, specifications, and/or local regulations. Users in other countries should consult with appropriate engineering and regulatory authorities for specific guidelines.

Correct use of all hardware is required for secure system suspension. Careful calculations should always be performed to ensure that all components are used within their rated workload before the array is suspended. Never exceed maximum recommended load ratings.

Before suspending any speaker system, always inspect all components (enclosure, rigging frames, pins, etc.) for cracks, deformations, corrosion, missing, loose, or damaged parts that could reduce the strength and safety of the array. Do not suspend the speaker until proper corrective action has been taken. Use only load-rated hardware when suspending Danley loudspeakers.

Are You New to Rigging?

If you are new to rigging, you should:

• Know the Rules for Safe Rigging.
• Attend a safe rigging seminar, such as those presented by professionals like Rigging Seminars or by Chain Motor Hoist manufacturers like Columbus McKinnon Corp. (manufacturers of the C/M Lodestar).
• Meet and establish a relationship with a licensed mechanical or structural engineer. Get in the habit of asking them questions instead of guessing about their answers. Learn from what they tell you.
• Meet and discuss this aspect of your business with your Insurance Agent.
• Research and understand the codes, practices, and requirements in the venues where you intend to operate your sound system.

General Hardware Information

All Danley loudspeakers intended for flown applications are provided with 3/8 inch - 16 hardware. Any hardware used in an overhead suspension application must be load-rated for the intended use. This type of hardware is generally available only from rigging supply houses, industrial supply catalogs, and specialized rigging distributors. Local hardware stores do not usually stock these products.

Attachment to Structures

A licensed Professional Engineer must approve the placement and method of attachment to structures prior to the installation of any overhead object. The following performance standards should be provided to the Professional Engineer for design purposes: Uniform Building Code as applicable, Municipal Building Code as applicable, Seismic Code as applicable. Installation of hardware and method of attachment must be carried out in the manner specified by the Professional Engineer. Improper installation may result in damage, injury, or death.

Rigging Hardware Inspection & Maintenance

Suspension systems are mechanical devices and require regular inspection and routine maintenance to ensure proper functionality. Danley loudspeakers must be inspected for fatigue at least annually. The inspection shall include a visual survey of all corners and load-bearing surfaces for signs of cracking, water damage, de-lamination, or any other condition that may decrease the strength of the loudspeaker enclosure. Accessory rigging hardware provided with or for Danley loudspeakers must also be inspected for fatigue at least annually. This inspection shall include a visual material survey for signs of corrosion, bending, or any other condition that may decrease the strength of the fastener. For other fittings used, refer to the manufacturer's inspection and maintenance guidelines.

Danley Sound Labs is not responsible for the application of its products for any purpose or the misuse of this information. Furthermore, Danley Sound Labs is not responsible for the abuse of its products caused by avoiding compliance with inspection and maintenance procedures or any other abuse. Prior to suspending the system, an expert, trained, and experienced in flying loudspeaker systems should inspect all rigging parts and components.

Section 4: Operation

4.1 Acoustic Level Warning

Danley Sound Labs loudspeakers can produce sound levels capable of causing permanent hearing damage from prolonged exposure. The higher the sound level, the less exposure needed to cause such damage. Avoid prolonged exposure to the high sound levels from the loudspeaker. Some Synergy Horns are capable of levels in excess of 140 dBSPL, which can cause permanent hearing loss. When operating at these high sound pressure levels, users are strongly encouraged to use hearing protection. Danley Sound Labs accepts no liability for hearing damage from using its loudspeakers.

4.2 Operator Responsibility

It is the responsibility of the operator to maintain safe operating levels and to ensure that the audience is not harmed by excessive levels. The following table shows the recommended exposure limits set by OSHA.

4.3 Aqua Tight Coating

The Aqua Tight Coating provides a full two-layer fiberglass finish for maximum moisture resistance, a special polyurea coat bonded to the fiberglass exterior, and two topcoat layers of UV-resistant color stabilizer. It also includes all stainless steel exterior fasteners, an acoustically transparent moisture barrier to the grille, waterproofing for the driver cones, and sealant for the input plate, handles, or cabinet fixtures. The finish includes a powder-coated stainless steel grille, sealed, waterproof cable leads (12' length standard), and fully caulked external joints (except for the "weep" opening at the bottom of the grille).

If a repair is to be made on a loudspeaker with an "AT" finish, specific steps must be taken to ensure the speaker remains water-resistant. The caulking must be removed to access the grill and driver panels. Once the repair is finalized, the bolts must be coated with silicone, and the caulk must be replaced on all removed panels.
