1
Line Input
8-channel pre-amplifier input to connect signal
sourc es such as radios. Input sensitivity is set to
4 Volts. It is possible to vary the sensitivity of each
channel from 2 Volts to 4 Volts inside the device.
2
Coax Input
Coaxial input in SPDIF format for connecting sour-
c es with a digital audio output. The sampling rate of
this input has to be in the range of 12 and 192 kHz.
The input signal is automatically adjusted to the in-
ternal sample rate. In order to control the volume of
this input, we recommend to use an optional remote
control.
Notice:
This processor can only handle stereo input
signals and no Dolby-coded digital audio stream.
3
Input Switch
With the Input Switch it is possible to choose bet-
ween the Coax Input“ and „Optical Input“. It is not
possible to use both inputs at the same time.
4
Optical Input
Optical input in SPDIF format for connecting signal
sources with a digital audio output. The sampling
rate of this input must be between 12 and 96 kHz.
The input signal is automatically adjusted to the in-
ternal sample rate.
In order to control the volume of this input, we re
-
commend to use an optional remote control.
Notice:
This processor can only handle stereo input
signals and no Dolby-coded digital audio stream.

Clipping LED
This LED lights up red if one of the eight „Line In-
puts“ or „Highlevel Inputs“ is overdriven. The LED
has no function if the device is fed with digital input
signals.
6
Highlevel Input
8-channel highlevel loudspeaker input.
Use this input to connect the processor directly to
loudspeaker outputs of OEM / aftermarket radios
or OEM amplifiers that do not have any pre-ampli
-
fier outputs. Input sensitivity is set to 10 Volts for
all channels. It is possible to vary the sensitivity of
each channel from 5 - 10 Volts rep. 10 - 20 Volts
inside the device.
By changing the sensitivity range, the input impe
-
dance of the highlevel inputs is shifted as well in or
-
der to guarantee a perfect operation in combination
with OE radios and high-power OE amplifiers. Input
impedance is set to 30 Ohms for a sensitivity range
of 5 - 10 Volts and 4 kOhms for a sensitivity range
of 10 - 20 Volts.
Attention:
Solely use the pluggable screw-terminal
for the highlevel connector which is included in de
-
livery!
7
Power Input
This input is used for connecting the processor
to the power supply of the vehicle and for remote
in / out.
If the highlevel loudspeaker inputs are used the
remote input can be left unconnected. The remote
output is used to control amplifier switching on and
off via the processor. Connect this remote output to
the remote inputs of your amplifier.
Attention:
Solely use the pluggable screw-terminal
which is included in delivery!
Important: Never use a different signal than the
remote output of the DSP to activate connected
amplifiers!
