9 Input Level

The control can be used to match the input sensiti-

vity of the individual channels to the output voltage

of the connected head unit. This control is not a vo-

lume control and is solely intended for the purpose

of sensitivity trimming. The adjustment range for the

low level input is 0,4 to 6 Volts and 1 - 15 Volts for

the high level input.

If the high level input is used with a standard car

radio we are recommending an input sensitivity of

9 Volts.

Phase

This control is used to adjust the phase from 0°

to 180°. This allows to match the subwoofers fre-

quency response with the other speaker systems

frequency response and ensures that there are no

frequency eliminations.

Bass Boost

This control is used to increase the bass response

at 45 Hz from 0 to +12 dB.

Subsonic

This control is used to adjust the crossover fre-

quency of the subsonic filter (high pass filter) from

10 to 50 Hz. The subsonic filter cuts off very low

frequencies which are not in the audible range and

relives the amplifier and the subwoofer. Additionally

the amplifier will have more power available for the

audible frequencies.

cy of the low pass filter from 30 to 250 Hz.
