Pole-Mounting Loudspeakers
Heed the following warnings when mounting a loudspeaker on a pole inserted into the
subwoofer.
•
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 pole.
•
Always verify that the pole is on a flat, level, and stable surface.
•
Inspect the 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. 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 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 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.
Hours per day SPL (dB) Example
8 90 Small gig
6 92 Train
4 95 Subway train
3 97 High level desktop monitors
