ACTPRO

INSTALLATION

Prior to operation, ensure the amplifier located on the rear of the enclosure has adequate
space behind it for proper ventilation. Ensure that all safety precautions regarding the
operation of loudspeakers and related electronic equipment are understood and adhered
to. Consult a licensed, Professional Engineer regarding physical equipment installation.
Do not modify the cabinet construction of any ACTPRO Series cabinet to suspend the
loudspeaker. Do not attempt to suspend any ACTPRO Series cabinet by the handles. Any
attempt to suspend an ACTPRO Series cabinet could result in injury or death.
COOLING
The ACTPRO loudspeakers use a power amplifier that produces heat. Provide a minimum
of 8" (203mm) clearance from the back of the cabinet to any wall for the convection
cooling to be efficient. Keep all objects that may restrict airflow away from the rear of the
enclosure (i.e boxes, draperies, fabric, etc...).
Do not operate any ACTPRO models, except ACTPRO12M, when oriented in a horizontal
position. Operating an ACTPRO Series cabinet in the horizontal position can cause over-
heating and thermal limiting. The cooling fins on the amplifier module must be vertical, in
order to disperse the heat generated by the amplifier efficiently.
ACTPRO12M is designed to be used as a floor monitor. When in horizontal position it
can operate long-term without overheating if not pushed to the limit. Observe proper
signal level to prevent overheating the ACTPRO12M in a floor monitor application.
During operation, or permanent installation of enclosures, do not position any ACTPRO
loudspeaker with its rear panel exposed to direct sunlight. Direct sunlight heats the
amplifier module and will limit its ability to produce full output long-term.
Do not install enclosures where rain or other water sources can contact the cabinet or
amplifier. Although durable, the ACTPRO Series enclosure is not weatherproof. Installation
in outdoor locations must provide protection from the elements.
