Hearing Damage
CAUTION: All professional loudspeaker systems are capable of generating very high sound pressure levels. Use care with placement and operation to
avoid exposure to excessive levels that can cause permanent hearing damage.
Suspension and Mounting
Installing speaker systems requires training and expertise. Improper speaker installation may result in injury, death, equipment damage, and legal
liability. Installation must be carried out by fully qualified installers, in accordance with all required safety codes and standards at the place of
installation.
Legal requirements for overhead installation vary by municipality, please consult the Building Inspector office before installing any product and
thoroughly check any laws and bylaws prior to installation. Installers that lack the skills, training, and proper ancillary equipment to install a speaker
system should not attempt to do so.
Installation
