DESCRIPTION OF OPERATION
LOW LEVEL INPUT
Connect the LOW LEVEL INPUT to the preamp outputs of the head unit. Use the enclosed RCA wire
harness for this.
13
12
OUTPUT
The OUTPUT RCA outputs provide a linear full-range audio signal for controlling additional ampliers
such as the monoblock PLUTO I. Use the RCA wire harness supplied for this.
FREQ.
These controllers determine the crossover frequency of the high or low pass lter on the respective
channel pair. The crossover frequency is adjustable from 40 Hz to 250 Hz (See section 9).
7
X-OVER MODE
This crossover switch selects the desired operating mode of the respective channel pair:
HPF: High-pass mode (frequency is limited downwards, adjustable via FREQ.)
FULL: Full range mode (entire frequency range is amplied)
LPF: Low-pass mode (frequency is limited upwards, adjustable via FREQ.)
9
INPUT MODE
This switch can be used to set whether the amplier should be controlled with just one stereo signal
(2CH) or with two stereo signals (4CH) from the head unit. The fader setting on the control unit is only
effective in switch position 4CH.
In switch position 2CH, the input signal is routed from the channel pair FRONT (FL/FR) to REAR (RL/
RR). This means that only a stereo signal is required at the inputs FL/FR.
11
BASS BOOST
With this switch you can set the bass boost (6dB or 12dB) on the respective channel pair. In the 0dB
switch position, there is no bass boost.
10
LEVEL
This controller determines the input sensitivity (adaptation to the output signal of the head unit).
