FUNCTIONS AND OPERATIONAL CONTROLS
ENG
The LINE INPUT RCA jacks must be connected with the RCA output jacks of the headunit.
The High Level Input is suitable to connect the speaker outputs of the headunit, if no pre-amplifier RCA outputs are available. Never
use the High Level Input and the RCA inputs at the same time. This may damage the amplifier seriously. Please observe by any means
the correct polarity of all connections.
The PHASE Switch allows to shift the phase from 0° to 180. By changing the acoustic phase you are able to adjust the subwoofer
according to the vehicle’s sound characteristics and the loudspeaker system.
The LOW PASS controller adjusts the cut-off point of the frequency range to above. This means all mids and highs will be eliminated
in the audio signal. The cut-off frequency is continuously adjustable from 40 Hz to 200 Hz.
