4-CHANNEL AMPLIFIER: TUNING and USE
Adjust the volume to the minimum and turn the car radio off. Set the BASS BOOST switches
on OFF position and the FILTER ones on FLAT; set the GAIN and X-OVER controls to the
minimum. If the BASS BOOST remote control is linked, set its level to the minimum.
Now turn on the car radio: after some seconds the amplifier is running and the PWR/PRT
led is lit (green).
Set the car radio volume approximately to 3/4 of
full volume; slowly increase the amplifier GAIN
controls: the right position is around the maximum
level with undistorted sound.
By the BASS BOOST switches, it is possible to
increase of 6 or 12 dB the bass frequencies.
If the remote control is linked, the amplifier switch of
CH3/CH4 channels is excluded: the bass boost is
continuously adjustable by the remote control knob.
