OPERATION
After the amplifier has been installed and all connections have been made
carefully and securely, turn the radio ON so that the amplifier is switched on
automatically. After a short power-on period, the amplifier reaches its full
performance. Now turn up the volume slowly using the volume control of the
radio. If there is no sound or only a distorted replay, switch off the radio
immediately - the amplifier will also switch off automatically - and check if all
connections have been made correctly.
GAIN = INPUT LEVEL CONTROL
The input level control allows the system to work well within a wide range of
output level. Choose the adjustment in the way that you achieve a sound
most possibly without any distortion.
As a guideline the following procedure is recommended:
• If you use several amplifiers, the adjustment has to be made for each set
separately. Tune in the volume of your car radio to2/3 of the maximum volume.
Now turn the gain control of the amplifier from “Min“ to “Max“ direction until
you can hear distortions. Then turn the level control a little back to "Min".
The gain control adjustment is finished now.
PHASE SHIFT
Allows you to change the phase of your subwoofer from 0 to 180 degrees to
help compensate for timing differences between drivers.
LOW PASS FILTER
The lower frequency under setting point can be pass.
SUBSONIC FILTER
