INPUT SENSITIVITY
Turn the INPUT LEVEL controller of the amplifier to the MIN position. Then turn the volume controller of the
head unit to 80 - 90% of its full setting. Now turn INPUT LEVEL clockwise until you hear some distortion. Then
turn back INPUT LEVEL slightly until you hear a cleaner sound.
VARIABLE BASS BOOST
By using the BASS BOOST controller you are able to increase the bass enhancement from 0 to 12 dB.
ATTENTION: Use the BASS BOOST wisely!
VARIABLE LOW PASS FILTER
Set the desired crossover frequency by using the controller LOW PASS. Thus to that only the frequencies
below the chosen crossover frequency will be amplified and the subwoofer plays more precisely and efficient.
PHASE SWITCH
The PHASE switch allows to switch the phase from 0° to 180° to match the output signal with the vehicle's
interior acoustic.
