FUNCTIONS AND OPERATIONAL CONTROLS

1
POWER/PROTECT
If the POWER LED lights up, the amplifier is ready for operation.
If the PROTECT LED lights up, a malfunction is indicated. Attend in this case the chapter TROUBLE SHOOTING.
3
The PHASE controller allows to adjust the phasing wave between 0° and 180°. Thereby you are able to adjust the
subwoofer perfect to the vehicle’s acustics.
6
The SUB SONIC controller (Subsonicfilter) limits the ultralow and not hearable frequencies of the audiosignal to below, to avoid
a mechanical and electical overloading on the subwoofer. The cut-off frequency is adjustable from 15 to 55 Hz and depends on
the size of the subwoofer.

The SLAVE OUTPUT RCA outputs are suitable to connect an additional amplifier (SLAVE AMP) and provide a modified audiosignal
in the LP-Mode. Attend therefor the chapter Interconnection Example: MASTER/SLAVE on page 21.

The REMOTE port is for the cable of the enclosed bass remote controller and only to use in the LP/BP mode. With this bass
remote controller, you are able to adjust the bass level e.g. out of the driver’s seat. Please use only the enclosed bass remote
controller and cable.
4
The EXTENDED BASS CONTROL controllers allow a extensive adjustment of the bass frequencies.
The SUB BOOST controller defines the bass bosst from 0 to 18dB.
With the FREQ RANGE controller you are able to adjust, on which frequency the bass boost (SUB BOOST) is effictive.
The range goes from 20 to 80 Hz.
With the Q CONTROL controller defines the Q-Factor of the crossover continuously, so that the playback quality of the cut-off
frequency can be adjusted. Thereby you are able to adjust perfect transitions between the loudspeakers.
• WIDE equates a Q-Factor of Q 0,3 (arrow left below) = very wide frequency range.
• NARROW equates a Q-Factor of Q 1,0 (arrow right below) = very narrow frequency range.
• Q 0,5 / LINKWITZ-REILLY is the standard-setting, this means the arrow points up (12 o’clock position).
• Q 0,7 / BUTTERWORTH is located at the arrow position right (3 o’clock position)
5
The MODE switch selects the required operation mode of the amplifier.
In the SLAVE-Mode the amplifier works as a SLAVE amp, this means only the audiosignal of the MASTER amp will be amplified.
All controllers on the SLAVE Amp are without function and will be assumed by the MASTER amp.
In the FULL-Mode a full range signal will be provided to the speakers. The controllers PHASE, LOW PASS, SUB SONIC and
the BASS REMOTE are without function.
In the LP-Mode (Low Pass mode) you are able to limit the frequencies to above with the LOW PASS controller. All controllers
are active.
The LINE INPUT RCA jacks must be connected with the RCA output jacks of the headunit.
10
The LOW PASS controller adjusts the cut-off point of the frequency range to above. The cut-off frequency is continuously
adjustable from 35 Hz to 250 Hz.
7
The LEVEL controller adjusts the input sensitivity of the amplifier to align the audio signal from the head unit.
The input sensitivity is adjustable from 6 to 0.2 Volts.
