PRECAUTIONS • Turn off all stereo devices before you begin. • Disconnect the negative (-) battery terminal from your vehicle’s battery. NOTE: check your vehicle’s owner’s manual before disconnecting the battery. On some newer vehicles, disconnecting the battery may require entering an anti-theft code upon reconnecting the battery and/or may require resetting the vehicle’s on-board computer.
POWER AND GROUND CONNECTIONS Technophonic is designed to work within a range of 12 volts to 14.4 volts DC. Before connecting any wiring, use a multi-meter to test the vehicle’s electrical system for adequate power supply. First, check the voltage at the positive (+) battery terminal with the ignition in the off position.
MOUNTING THE AMPLIFIER It is best to mount the amplifier in a location that allows air to freely circulate around it and allows access to the end panel controls for adjustments. Although both thermal and overload protection are built in, if the amplifier overheats it will reduce its power output to maintain operation.

CONTROL PANEL LAYOUT LPF (Low Pass Filter) The LPF (adjustable between 50Hz and 250Hz) filters out frequencies above the designated setting on the amplifier while attenuating frequencies below that setting. Mode The Mode control switch toggles the input mode of the amplifier between 2 channel, 4 channel and 5 channel operation.
TROUBLESHOOTING PROBLEM SOLUTION Green Power LED does not turn on • Check to ensure that the Battery (+) (12 volt constant) wire has 12 to 14.4 volts. • Check to ensure that the amplifier turn-on lead has 12 volts. • Check the fuses at bottom of the amplifier.
