14. Rigging Precautions: When mounting or suspending EAW Commercial loudspeaker enclosures, it is essential that load ratings, rigging techniques, and special safety considerations be appropriate for the installation. 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.
2. INTRODUCTION Congratulations on the purchase of your new EAW Commercial loudspeaker. You now own one of the finest professional audio products available – the result of exceptional engineering and meticulous craftsmanship. Please read these instructions to get the maximum performance from your new loudspeaker. Each EAW Commercial loudspeaker is intended for professional use. The construction, components, and hardware have been designed to provide robust, reliable performance for its intended application.
3. INSTALLATION Unpacking and Inspection Visually inspect the outside of the shipping carton and check for any damage. 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. Although EAW Commercial will help in any way possible, it is always the responsibility of the receiving party to file any shipping damage claim. The carrier will help prepare and file this claim.

Make your speaker-wire connections before proceeding. Warning: Installation should only be done by an experienced technician. Improper installation may result in damage to the equipment, injury or death. 1. Mounting the Fly Bracket to the Enclosure: SCREW 1/4 INCH-20 X 1.
4. Mounting the Enclosure/Fly Bracket Assembly to the Wall Bracket: The fly bracket is used to secure the enclosure to the wall bracket. The enclosure may be tilted forward at various angles or mounted vertically. For a forward tilt, refer to the figure to the right and these instructions: CONNECTING BRACKET WALL BRACKET LOCK NUT 1/4 INCH-20 3 PLACES a. Insert a 4.

Loudspeaker Cables • Use loudspeaker cables with a minimum conductor size for the length you need, as listed in these tables. This will minimize power losses to less than 0.5 dB. The cable lengths listed are “up to” lengths. For in-between lengths, use the next larger conductor gauge. Using larger than the recommended conductor size is always permissible. Using smaller than recommended conductor size will result in higher power losses.
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.
