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.

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.
