Stand-Mounting
Always install speakers in accordance with applicable electrical and building codes.
Install the speaker according to its maximum weight.
Do not mount multiple speakers 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 speaker system. Such
attachments could act as a sail and topple the system.
Unless you are confident that you can handle the speaker'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 speaker 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.
