Page 7: Mounting The Amplifier
Mounting The Amplifier Leave 2” to 5” of clearance for proper airflow. 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. -
Page 8: Power And Ground Connections
Power and Ground Connections Electrical System Test The Technophonic amplifier 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 battery with the ignition in the off position. - Page 9 Power and Ground Connections Constant 12 volt (+) Battery Wire The constant 12 volt (+) battery wire (not included) should be wired directly to the vehicle’s positive (+) battery terminal using 8 to 4 gauge primary wire de- pending on run length. Start at the vehicle’s battery, and run the cable back to the amplifier.

Page 10: Fuses
The fuses included with the Technophonic amplifier are to replace the internal fuses and only protect the amplifier itself in case of short-circuit. To replace the internal fuses, remove the panel on the bottom of the amplifier and replace the blown fuses as needed. -

2 on the amplifier. The rear RCA outputs connect to channels 3 and 4. The RCA outputs for the subwoofer connect to both inputs on channel 5 of the Technophonic amplifier. For radios with only 2 or 4 outputs use the mode select switch (see page 15). -
Page 12: Wiring: Speaker Connections | 5 Channel
Wiring: Speaker Connections | 5 Channel For five speaker systems, connect the speakers to channels 1-5. Strip 1/2 inch (12 mm) of insulation from the end of each wire and twist the ends. Back out the set screws 3/4 of the way out and insert each wire firmly and completely, leaving no exposed wire. -

Page 14: Controls
Controls A. High Pass Filter (HPF) The HPF (adjustable between 40Hz and 400Hz) filters out high frequencies below the designated setting on the amplifier while attenuating frequencies above that setting. B. Low Pass Filter (LPF) The LPF (adjustable between 50Hz and 250Hz) filters out low frequencies above the designated setting on the amplifier while attenuating frequencies below that setting. - Page 15 Controls E. Gain Controls This control is used to match the input sensitivity of the amplifier to the radio. The Gain Control is not a volume control. Use the source unit (radio) to control system volume. Use these steps to properly set all three gains: 1.

Page 16: Mode Select Switch
Mode Select Switch The Technophonic amp can be set to two, four or five channel mode to match the number of outputs the connected radio has. When set to two or four channel modes the amplifier will create the additional outputs internally so all five outputs can be used. -
Page 17: Troubleshooting
Troubleshooting Problem Solution • Check to ensure that the Battery (+)(12 volt constant) wire has 12 to 14.4 volts. Green Power LED • Check to ensure that the amplifier does not turn on turn-on lead has 12 volts. • Check the fuses at bottom of the amplifier. -
