WIRING AND ELECTRICAL SAFETY

STANDARD WIRING

All standard R-MAX loudspeakers come with attached

SJOW rated input cables, 12' (3.6m) in length. The cable enters the enclosure through a waterproof gland nut. The other end of the cable is un-terminated. The designer must account and compensate for cable losses between the amplifier and the speaker system. Do not remove the gland nut attaching the cable to the rear of the loudspeaker, as this will compromise the weather integrity of the enclosure.

Please contact Community’s TAG Team (Technical

Applications Group) for additional assistance (email: [email protected], phone: (610) 876-3400, or toll-free (800) 523-4934 in the US and Canada).

Wire the loudspeaker. A typical installation method is to bring the cable into a waterproof junction box (J-box) equipped with a waterproof gland nut. Connections within the J-box may be made with barrel-type crimp connectors, wire nuts, solder and heat-shrink, or terminal strips.

Terminate per your local electrical code. We recommend using barrel-type crimp connectors that are crimped with a forged crimp or a ratcheting tool, as this method, when properly executed, results in a gas-tight connection that is easy to accomplish.

WARNING: After wiring the amplifier(s) to the loudspeaker(s), first power-up all devices that are upstream of the amplifier, such as mixers, equalizers, compressor/limiters, etc., before powering-up the amplifier.

This is to avoid passing any clicks or pops that may originate in the upstream devices to the loudspeakers. The amplifier should initially be powered-up with its gain controls turned all the way down. After making sure that a continuous signal is present, such as a CD playing, slowly raise the level of the gain controls to establish that the wiring has been installed correctly. Only then should the loudspeaker be operated at normal output levels.

FINAL ASSEMBLY AND TESTING

(–) ( Black)

(+) ( White)

All R2-MAX are biamp models and have color coded gland nuts (and a label on the enclosure - see Figure 8 below) that will indicate what input the cable is designated for.

The cables are 2-conductor standard weather-resistant

IMPORTANT: All electrical installation connections for loudspeaker lines are subject to all applicable governmental building and fire codes. The selection of appropriate electrical hardware to interface with the

R SERIES loudspeaker lies solely with the installation professional. Community recommends that an appropriately licensed engineer, electrician, or other qualified professional identify and select the appropriate conduit, fittings, wire, etc. for the installation.

Figure 8. Labeled cables - R2-MAX

The R6-51MAX is a triamp loudspeaker and the cables are labeled to indicate the type of output (LF/MF/HF). DANGER: The output power capabilities of audio amplifiers present a danger to installers. To minimize the risk of electric shock from loudspeaker connecting cables, confirm that the power amplifiers are turned “off" before connecting loudspeaker cable(s) to the loudspeaker or amplifier. Always follow local electrical codes and proper electrical safety procedures.

All holes should be filled with the provided hardware or other suitable replacement in order to maintain weatherresistance.

Attach a safety cable to an attachment point on each loudspeaker. The safety cable and hardware are not included. Please consult a structural engineer for the appropriate cable for the load and application. The safety cable attachment points should not be located on opposite sides of the cabinet in such a manner that they present a significant force that pulls the insert points away from each other. The safety cable must be secured to a suitable loadbearing point separate from the loudspeaker mounting point, with as little slack as possible, so as not to develop undue kinetic force if the R SERIES mounting were to fail.
