2-CHANNEL AMPLIFIER: TUNING and USE
Adjust the volume to the minimum and turn the car radio off. Set the BASS BOOST switch
on OFF position and the FILTER one on FLAT; set the GAIN and X-OVER controls 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
control: the right position is around the maximum
level with undistorted sound.
By the BASS BOOST switch, it is possible to increase
of 6 or 12 dB the bass frequencies level around
50 Hertz.
