WARNINGS AND CAUTIONS:
WARNING – THIS AMPLIFIER MODULE IS DESIGNED FOR INSTALLATION INTO A
SUBWOOFER ENCLOSURE, OR INTO ITS OWN ENCLOSURE. WHEN PROPERLY
INSTALLED, ONLY THE EXTERIOR FACEPLATE SHOULD BE ACCESSIBLE TO THE USER –
ANY OTHER CONFIGURATION IS NOT SAFE FOR THE CASUAL USER. IT IS IMPORTANT
THAT THIS MODULE BE PROPERLY HOUSED TO PREVENT ACCIDENTAL CONTACT WITH
DANGEROUS VOLTAGES – BOTH MAINS AC (120VAC) AS WELL AS HIGH VOLTAGE DC
(>42VDC). THESE VOLTAGES CAN INJURE AND KILL AND SHOULD BE TREATED WITH
RESPECT.
WARNING – AS WITH ANY PIECE OF ENTERTAINMENT ELECTRONICS, THIS MODULE IS
INTENDED FOR INDOOR USE. IT SHOULD NOT BE EXPOSED TO WATER (INCLUDING
CONDENSATION).
CAUTION – The amplifier relies on convection cooling, so air must pass freely over
the faceplate. Do not mount the amplifier in a location where faceplate airflow is
blocked. The amplifier does include overtemperature protection and will shut down
if overheated. This thermal protection will automatically reset once the amplifier is
cool.
CAUTION – This amplifier is designed for use with drivers that are rated at 4
Ù
or
greater. Drivers whose nominal impedance rating is less than 4
Ù can damage the
amplifier. Driver combinations (this includes any configuration where there are
multiple voice coils) that result in a load of less than 4
Ù (when calculated using the
driver’s nominal impedance) can damage the amplifier. Damage caused by low
impedance loads are not covered by the warranty.
