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 (115VAC OR 230VAC) 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 –
Damage not covered by the warranty can occur if the AC SELECT switch
setting does not match the actual AC input voltage.
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 4Ù or
greater. Drivers whose nominal impedance rating is less than 4Ù can damage the
amplifier. Driver combinations (this includes any configuration where there are
multiple voice coils) that result in a load of less than 4Ù (when calculated using the
driver’s nominal impedance) can damage the amplifier.
Damage caused by low
impedance loads are not covered by the warranty.
