- Follow all instructions.
- Clean only with a dry cloth.
- Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
- Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
- Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for the replacement of the obsolete outlet.
- The power plug at the wall must remain accessible to be able to disconnect power from the apparatus.
- Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
- Only use attachments/accessories specified by the manufacturer.
- Unplug this apparatus during lightning storms or when unused for long periods of time.
- Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
- This apparatus shall not be exposed to dripping or splashing, and no object filled with liquid, such as vases, shall be placed on the apparatus.
- This apparatus has been designed with Class-I construction and must be connected to a main socket outlet with a protective grounding connection (the third grounding prong).
- If the loudspeaker is exposed to changes in temperature and humidity, internal condensation may develop. If powered up with such condensation, electronic failure could result. When exposed to environmental changes, allow the loudspeaker at least 30 minutes to acclimate to a new temperature before connecting to the ac mains and operating.
- 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 is needed to cause such damage. Avoid prolonged exposure to the high sound levels from the loudspeaker.

Shipping Damage
If your Loudspeaker appears to have been damaged in shipping, please take
clear photographs and contact the carrier immediately.
Understanding the Difference
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 wide frequency response.
Initial Set Up
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 amplifier for the application. We recommend choosing an amp that is rated between the continuous and program ratings. Please note that “Continuous” does not mean “forever”! Most loudspeaker manufacturers, including Danley Sound Labs, subscribe to the AES standards for loudspeaker power ratings.
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 parallel.
Pinout: Passive
- Positive Full Range
- Negative FullRange
- Pass-Through
- Pass-Through
Pinout: Bi-amp
- Positive LF
- Negative LF
- Positive Mid/High
- Negative Mid/High
Switch Modes for SH96HO, SH46 and SM80M
The SH96HO, SH46, and SM80M can be run two ways; Bi-amp or passive. In the
passive mode, the connection is to pins +1 and -1. In Bi-amp mode connect the
low-frequency amp channel to pins 1+ and 1- of the NL4 and the high/mid
channel to pins 2+ and 2-. In addition, the four 15-inch woofers on the SH96HO
can be switched to present a 2 or 8-ohm load.
On the “Passive” setting there is an internal passive crossover. Using an
SH96HO in passive mode should be viewed as a compromise. It is sort of like
paying extra for the high horsepower engine and setting a 55 MPH governor on
it! In the passive / 8 ohm mode the low end will be a significantly lower
level. This may be acceptable if the SH96HO is part of a larger cluster where
there are a number of woofers coupling together. It is also useful if there
are unavoidable very long speaker runs and/ or the amplifier is not capable of
delivering the desired power into 2 ohms. For the more low-end in the passive
mode, use the 2-ohm setting.
You can also select the BIAMP setting. The BIAMP setting will allow the SH96HO
to realize its full potential as a true high-output device! In the BIAMP
setting, there is no crossover applied to the four 15 inch drivers! You are
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. The high/midsection is high
passed at 400 Hz at 24 dB Butterworth. In the 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, make sure that the amplifier you
have chosen 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.
Impedance
On the SH96HO, in the active mode, the impedance of the low-frequency section will be selected by the toggle switch, either 2 ohms or 8 ohms. The mid/high section will be 4 ohms. Since 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 the passive mode the SH96HO presents a nominal 2 Ohm load.
Rigging
If you have to ask how you probably shouldn’t be doing it!
Safety Precautions
Before attempting to rig or suspend your Danley speakers, read and understand
the following safety information.
IMPORTANT RIGGING SAFETY WARNING!
The information in this section has been assembled from recognized engineering
data and is intended for informational purposes only. None of the information
in this section should be used without first obtaining competent advice with
respect to the applicability to a given circumstance. None of the information
presented herein is intended as a representation or warranty on the part of
Danley Sound Labs. 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

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 security 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 the maximum recommended load ratings. Before suspending any speaker
system always inspect all components (enclosure, rigging frames, pins, etc.)
for cracks, deformations, corrosion, and missing, loose or damaged parts that
could reduce the strength and safety of the array. Do not suspend the speaker
until the 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 do the following:
Know the Rules for Safe Rigging.
Attend a safe rigging seminar, such as that 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 which are intended to be flown are provided with ⅜
inch – 16 hardware. Any hardware used in an
overhead suspension application must be load rated for the intended use.
Generally, this type of hardware is 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 placement and method of
attachment to structures prior to 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, and 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 comprised of mechanical devices and, as such, they
require regular inspection and routine maintenance to ensure proper function
ability. 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 be
inspected for fatigue at least annually. The 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 for the process.
Danley Sound Labs is not responsible for the application of its products for
any purpose or the misuse of this information for any purpose. 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.
Operation
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 is 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! Levels this high can cause permanent hearing loss! When operating at these high sound pressure levels the user is strongly encouraged to use hearing protection. Danley Sound Labs accepts no liability for hearing damage from using our loudspeakers!
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. This is a chart
of the recommended exposure limits set by OSHA. 
Aqua Tight Coating
Aqua Tight Coating includes a full two-layer fiberglass finish for maximum moisture resistance as well as a special polyurea coat bonded to the fiberglass exterior & 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 of the 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 all 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, a few steps must be taken to insure the speaker remains water-resistant in future usage. The caulking must be removed to free the grill and driver access panels. Once the repair is finalized, the bolts must be coated with silicon and the caulk must be replaced on all panels that have been removed.
