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 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 mains 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 needed to cause such damage. Avoid prolonged exposure to the high sound levels from the loudspeaker.

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 a 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 amplifiers for the application. We recommend choosing an amp that
is rated between the continuous and program ratings. Please note “Continuous”
does not mean “forever”! Most loudspeaker manufactures, 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
- 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
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 a 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 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 high pass of 40 Hz at 24 dB Butterworth and 600 Hz at 12 dB Butterworth. The high/mid section 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
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 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

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 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, 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 insure 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 strength of the fastener. For other fittings used, refer to the
manufacturer’s inspection and maintenance guidelines for 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 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
encourages 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 insure 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 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 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 “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.
