Use only the mounting/rigging points on the loudspeaker enclosure intended for this purpose. The user must determine the load requirements, dynamic loading, and any other contributing factors affecting the loudspeaker installation.

After unpacking, if you find concealed damage to the loudspeaker, save the packing materials for the carrier’s inspection, notify the carrier immediately, and file a shipping damage claim.
Mounting Instructions 1. Remove the screw from each end of the enclosure as shown below. 2. Align the bracket slots with the mounting holes on each end of the enclosure. Make sure the four openings in the bracket arms face upward. 3. Onto each of the two supplied hex-head screws, place a lock washer, and a flat washer.

4. CONNECTIONS WARNING: To prevent the risk of electric shock, do not connect the loudspeaker with the amplifier switched on. The protective cover over the terminal strip is a safety feature per CE requirements. Replace this cover after making the signal connections. 1. Remove the insulating cover from the loudspeaker input terminal strip. 2. The positive (+) input terminal of the loudspeaker connects to the positive (+) output of your power amplifier. 3.
Precautions • To prevent inductive phenomena causing humming or distortion, the speaker cables should not be run together with electrical energy conductors, microphone cables, or line-level audio lines. • Use speaker cables that have markings to distinguish the polarity, such as insulation or conductors of different colors. • Before using the loudspeaker, carefully check that all the connections have been made correctly to make sure there are no accidental short circuits that could cause electrical sparks.
5. OPERATION Signal Processing Sometimes external signal processing is desirable to “voice” the loudspeaker to accommodate particular program material, less than optimum acoustics, feedback control, or personal taste. For these purposes, use a suitable electronic signal processor. This can be as simple as a 1/3 octave graphic equalizer or a fully capable DSP (digital signal processor) such as the EAW Commercial DX810, or the EAW MX8750.

7. TROUBLESHOOTING Loudspeaker difficulties usually fall into one of the following categories. The causes for each are listed in the most likely order of probability. No Sound or Low Output • Loudspeaker cables or connectors are not wired correctly or are faulty. Check all cabling, referring to these instructions for the correct connections. The best way to check a suspect cable is to swap it with a known good cable. Check the loudspeaker’s input panel to verify correct cable connections.
8. SERVICE and MAINTENANCE Maintenance Usually, your EAW Commercial loudspeaker will not require regular maintenance for normal use. However, you can do several things to keep your loudspeaker in good operating and cosmetic condition. • Testing: Periodically test your loudspeaker for proper performance. A simple test is to play a CD through it using well-defined, articulate, wide-range program material.
