The LEVEL controller adjusts the input sensitivity of the amplifier, to adjust the audio signal of the headunit. The input sensitivity
4
is adjustable from 6 Volts (MIN) to 0.2 Volts (MAX).
The PHASE controller allows to adjust the phasing between 0° and 180°. Hence, you are able to adjust the subwoofer perfect
5
to the vehicle's acustics.
The EXTENDED BASS CONTROL controllers allow a extensive adjustment of the bass frequencies.
6
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)
The SUB SONIC controller (Subsonic filter) limits the ultralow and not hearable frequencies of the audiosignal to below, to avoid
7
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. Is this controller adjusted higher that the LP controller, no sound is hearable.
The LP controller adjusts the cut-off point of the frequency range to above. The cut-off frequency is continuously adjustable from
8
35 Hz to 250 Hz.
The MODE switch selects the required operation mode of the amplifier.
9
In SLAVE-Mode the amplifier works as a SLAVE amp, this means only the audiosignal of the MASTER amp will be amplified.
Then, all controllers on the SLAVE Amp are without function and will be controlled by the MASTER amp.
In MASTER-Mode (Low Pass mode) you are able to limit the frequencies to above with the LP controller. All controllers are acti-
ve. When you use only one amplifier, the MODE switch must be in position MASTER.
The BASS LEVEL CONTROLLER port is for the cable of the enclosed bass remote controller and only to use in the MASTER
10
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.
POWER/PROTECT
11
If the POWER LED lights up, the amplifier is ready for operation.
If the PROTECT LED lights up, a malfunction is indicated. Refer in this case to the chapter TROUBLE SHOOTING.
The SLAVE IN/OUT RCA jacks are suitable to connect an additional amplifier in MASTER/SLAVE mode.
12
Refer to the chapter Interconnection Example: MASTER/SLAVE on page 23..
NOTE
Installation of RCA/Audio signal cables and power supply cables.
Ensure while installation not to lead the audio cables between the head unit and the amplifier together with the power supply wires
on the same side of the vehicle. The best is a real separated installation on the left and right cable channel of the vehicle to avoid
interferences on the audio signal. This stands also for the enclosed bass-remote wire, which should not be installed together with the
power supply wires.
