CAUTION: Allow at least six inches of free space all around the amplifier heat sink for sufficient ventilation.

Understanding Sound Levels and Exposure Limits

Danley Sound Labs loudspeakers can produce sound levels capable of causing permanent hearing damage from prolonged exposure. Avoid prolonged exposure to high sound levels. Some Synergy Horns are capable of levels in excess of 140 dBSPL, which can cause permanent hearing loss. Users are strongly encouraged to use hearing protection at these high sound pressure levels. Danley Sound Labs accepts no liability for hearing damage from using their loudspeakers.

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 chart shows recommended exposure limits set by OSHA:

The decibel levels and their associated risks are illustrated as follows:

• 140 dB: PAIN THRESHOLD, Jet engine at takeoff [✈️]

Section 1: Your New Loudspeaker

1.1 Unpacking

For most Danley Sound Labs products, unpacking by two or more people is recommended. Refer to the specification sheet for product weight. Remove tape and open top flaps. Lay the box on its side and slide the loudspeaker out. Remove the packaging wrap.

1.2 Inspection

Check to ensure the product is not missing any hardware. If any brackets or additional accessory hardware is missing, please contact Danley Sound Labs.

1.3 Shipping Damage

If your loudspeaker appears to have been damaged in shipping, please take clear photographs and contact the carrier immediately.

Section 2: Understanding the Difference

2.1 THE SYNERGY HORN

The Synergy Horn successfully couples the radiation from multiple drivers into a single horn, yielding 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, adhere to the AES standards for loudspeaker power ratings.

3.2 Connecting to the Synergy Horn

Your Danley loudspeaker has two NL4 ("speak-on") connectors located on a panel on the rear of the box. 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

Wiring View of an NL4 Connector: Depicts the NL4 connector with pins labeled 1+, 1-, 2+, 2-. A diagram shows the parallel wiring of NL4 connectors for passive mode, connecting to a crossover and then to drivers. Another diagram illustrates the signal path for bi-amp mode, showing connections to a crossover and then to separate low-frequency (LF) and mid/high drivers.

Section 3 (Continued): Switch Modes, Impedance, and Rigging

3.3 Switch Modes for SH96HO, SH46 and SM80M

The SH96HO, SH46, and SM80M can be operated in two ways: 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.

3.3.1 Passive Mode

In the "Passive" setting, an internal passive crossover is used. Using a SH96HO in passive mode is considered a compromise. In the passive / 8 ohm mode, the low end will be at a significantly lower level. This may be acceptable if the SH96HO is part of a larger cluster where multiple woofers couple together. It is also useful for very long speaker runs or if the amplifier cannot deliver the desired power into 2 ohms. For more low end in passive mode, use the 2 ohm setting.

3.3.2 Bi-amp Mode

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 and 600 Hz at 12 dB Butterworth for the low frequency. The high/mid section should be high-passed at 400 Hz at 24 dB Butterworth.

In BIAMP setting, you can also select between a two-ohm load and an eight-ohm load for the woofers. CAUTION: If you select the 2-ohm setting, ensure the chosen amplifier can accommodate 2-ohm loads. When running a 2-ohm load, the resistance of the speaker cable becomes significant; use the largest gauge and shortest run possible.

Wiring Diagrams: Illustrations show connections for PASSIVE MODE, SH96HO BIAMP MODE, and SH46 BIAMP MODE. These diagrams detail how drivers and crossovers are connected via NL4 inputs, including the 2ohm/8ohm switch for the SH96HO.

3.4 Impedance

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

3.5 Rigging

Safety Precautions: 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 for informational purposes only. None of this information should be used without obtaining competent advice regarding its applicability to a specific circumstance. Danley Sound Labs makes no representation or warranty regarding this information, and users assume all liability arising from its use. Information presented is based on North American practices and may not apply to other countries; users in other countries should consult appropriate engineering and regulatory authorities.

Correct use of all hardware is required for secure system suspension. Careful calculations must be performed to ensure all components are 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 strength and safety. 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 (e.g., presented by Rigging Seminars or Chain Motor Hoist manufacturers like Columbus McKinnon Corp.).
• Establish a relationship with a licensed mechanical or structural engineer and ask questions.
• Discuss rigging 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 flying 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 typically available from rigging supply houses, industrial supply catalogs, and specialized rigging distributors; local hardware stores usually do not stock these products.

Attachment to Structures

A licensed Professional Engineer must approve the placement and method of attachment to structures prior to installing any overhead object. The following performance standards should be provided to the engineer: Uniform Building Code, Municipal Building Code, and Seismic Code as applicable. Installation of hardware and method of attachment must follow the engineer's specifications. Improper installation may result in damage, injury, or death.

Rigging Hardware Inspection & Maintenance

Suspension systems are mechanical devices requiring regular inspection and routine maintenance. Danley loudspeakers must be inspected for fatigue at least annually. This inspection should 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 enclosure's strength. Accessory rigging hardware must also be inspected for fatigue at least annually, including a visual material survey for signs of corrosion, bending, or other conditions that may decrease fastener strength. Refer to manufacturer guidelines for other fittings.

Danley Sound Labs is not responsible for the application or misuse of its products or for abuse caused by avoiding inspection and maintenance procedures. 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. Avoid prolonged exposure to high sound levels. Some Synergy Horns can exceed 140 dBSPL, potentially causing permanent hearing loss. Users operating at these levels are strongly encouraged to use hearing protection. Danley Sound Labs accepts no liability for hearing damage.

4.2 Operator Responsibility

The operator is responsible for maintaining safe operating levels and ensuring the audience is not harmed by excessive levels.

4.3 Aqua Tight Coating

The Aqua Tight Coating features 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 includes all stainless steel exterior fasteners, an acoustically transparent moisture barrier to the grille, waterproofing for driver cones, and sealant for the input plate, handles, or cabinet fixtures. The finish also 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 needed 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 silicon, and the caulking must be replaced on all removed panels.
