2 SCP (Smart Control Port)
This multi-functional input is designed for HELIX
V TWELVE DSP MK2 accessory products like a re-
mote control which allows to adjust several features
of the signal processor. Depending on the type of
remote control, at first its functionality has to be
defined in the " Device Configuration Menu" of the
DSP PC-Tool software.

3 Control pushbutton
The V TWELVE DSP MK2 provides 10 internal
memory locations for sound setups. The Control
pushbutton allows the user to switch between two
memory locations or to perform a device reset. The
setups can be defined in the DSP PC-Tool.
1. Setup switch: Press Control pushbutton for 1 sec-
ond. The memory locations one and two are defined
by default. Switching is indicated by a single red
flash of the Status LED. Alternatively, the optional
URC.3 remote control can be used for switching.
To switch between all internal memory locations,
optional accessories like the DIRECTOR display
remote control, CONDUCTOR or WIFI CONTROL
are required.

2. Device reset: Press pushbutton for five seconds.
This completely erases the internal memory and is
indicated by a continuous red glowing and constant
green flashing of the Status LED.
Attention: After erasing the setups from memory
the V TWELVE DSP MK2 will not reproduce any
audio output until the device is updated via the DSP
PC-Tool software.
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 adapted to the in-
ternal sample rate.
In order to control the volume of this input, we rec-
ommend to use an optional remote control or the
WIFI CONTROL.
Note: This amplifier can only handle stereo input
signals and no MP3- or Dolby-coded digital audio
stream!
Note: In standard configuration the manual activa-
tion via an optional remote control is configured.
5 Highlevel Input
12-channel highlevel loudspeaker input to connect
the amplifier directly to loudspeaker outputs of
OEM / aftermarket radios or OEM amplifiers that do
not have any pre-amplifier outputs. Input sensitivity
is factory-set to 11,3 Volts. However, it is possible
to optimally adapt the input sensitivity to the sig-
nal source using the DSP PC-Tool software (DCM
menu → Signal Management) and by repositioning
jumpers inside the device (see page 30, point 4; Ad-
justment of the input sensitivity).
Important: It is mandatory to properly adapt the
input sensitivity of the V TWELVE DSP MK2 to
the signal source before first use. Disregarding
this may cause severe damage to the amplifier.
Attention: Solely use the pluggable screw-termi-
nals for the highlevel connectors which are included
in delivery or an optional available cable harness
from the HELIX accessory assortment!
