The LEVEL controller adjusts the input sensitivity and allows to control the output level of the subwoofer.
1
The PHASE controller allows to adjust the phase between 0° to 180. By changing the acoustic phase you are able to adjust the subwoofer
2
according to the louspeaker system and the vehicle's sound characteristics.
The BASS BOOST controller adjusts the bass boost enhancement continuously from 0dB to +12dB at 45 Hz.
3
The LOW PASS controller adjusts the cut-off point of the frequency range to above. This means all mids and highs will be eliminated
4
in the audio signal. The cut-off frequency is continuously adjustable from 70 Hz to 200 Hz.
The POWER LED lights up when the soundsystem is turned-on and ready for operation.
5
The POWER switch activates the "auto-turn-on function" by detecting the incoming audio signal while using the „High Level Input"
6
(Position ON). If you rather want to use a turn-on-signal (REMOTE) from your headunit like described in the chapter ELECTRICAL
CONNECTIONS section 3 choose the Position OFF on the POWER switch. The amplifier will turn-off after 1 minute, if no signal input
is detected.
NOTE: If the amplifier turns off while listening to quiet music, we suggest to use an additional designated turn-on-signal (Remote) from
the headunit, which needs to be connected with the REM terminal (POWER INPUT). If your headunit is not equipped with a designated
turn-on-signal, you can use if applicable the +12V ignition of the vehicle (Please protect this connection with an appropriate fuse).
This switch has no function, when the RCA Level Inputs are used.
The LINE INPUT RCA jacks must be connected with the RCA output jacks of the headunit.
7
The High Level Input is suitable to connect the speaker outputs of the headunit, if no pre-amplifier RCA outputs are available. Please
8
use the include wire harness for the connection. Please observe by any means the correct polarity of all connections. Never use the High
Level Input and the RCA inputs at the same time. This may damage the amplifier seriously.
If no separate turn-on-signal (Remote) is connected, the POWER switch must be in Position ON.
The Remote terminal is for the connection of the included bass Remote Controller. This controller allows to adjust the bass level of the
9
soundsystem e.g. from the driver's seat.
The Remote Controller works as a level attenuator, this means you cannot excess the level, which you have adjusted on the LEVEL
controller (section 1).
