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

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.

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 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 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.
