outlet while the grille is removed.
Stand-Mounting
•
Always install loudspeakers in accordance with applicable electrical and building codes.
•
Install the loudspeaker according to its maximum weight. Check the specifications of your stand or
pole to ensure it can support the loudspeaker’s weight. Also, observe all safety precautions specified
by the manufacturer.
•
Do not mount multiple loudspeakers on the same stand or pole.
•
Always verify that the stand or pole is on a flat, level, and stable surface. Also, fully extend the legs of
tripod-style stands, and ensure its legs do not present a trip hazard.
•
Inspect the stand (or pole and associated hardware) before each use and do not use equipment with
worn, damaged, or missing parts.
•
Always be cautious in windy, outdoor conditions. You may need to place additional weight (e.g.,
sandbags) on stand’s base to improve stability. Do not attach banners or similar items to any part of a
loudspeaker system. Such attachments could act as a sail and topple the system.
•
Unless you are confident that you can handle the loudspeaker’s weight, ask another person to help
you lift it onto the stand or pole.
•
Make sure your cables are out of the way of performers, production crew, and audience so they will
not trip over them, pulling the loudspeaker off the stand or pole.
Sound Level
Permanent hearing loss may be caused by exposure to extremely high noise levels. The U.S. Occupational
Safety and Health Administration (OSHA) has specified permissible exposures to certain noise levels.
According to OSHA, exposure to high sound pressure levels (SPL) in excess of these limits may result in
hearing loss. When using equipment capable of generating high SPL, use hearing protection while such
equipment is under operation.
