Control Input
This multi-functional input is designed for HELIX
V TWELVE DSP accessory products like a remote
control which allows to adjust several features of
the amplier. Depending on the type of remote con-
trol, at rst its functionality has to be dened in the
“ Device Conguration Menu” of the DSP PC-Tool
software.

Control pushbutton
The V TWELVE DSP provides 10 internal memory
locations for sound setups. The Control pushbutton
allows the user to switch between two memory po-
sitions. These can be dened in the DSP PC-Tool.
Pressing the button for ve seconds completely
erases the internal memory. This is indicated by a
continuous red glowing and constant green ashing
of the Status LED.
Note: The memory locations one and two are de-
ned ex works. To manually switch between the
setups the button has to be pressed and held for
one second. Switching is indicated by a single red
ash of the Status LED. To switch between all in-
ternal memory locations, the optionally available
DIRECTOR display remote control or the HELIX
WIFI CONTROL is recommended.
Attention: After erasing the setups from memory
the HELIX TWELVE DSP will not reproduce any
audio output.

Status LED
The Status LED indicates the operating mode of the
amplier and of its memory.
Green: Amplier is ready for operation.
Orange: Power Save Mode is active.
Red: Protection Mode is active. This may have dif-
ferent root causes. The HELIX V TWELVE DSP is
equipped with protection circuits against over- and
undervoltage as well as overheating. Please check
for connecting failures such as short-circuits or oth-
er wrong connections.
If the amplier is overheated the internal tempera-
ture protection switches o󰀨 the remote and signal
output until it reaches a safe temperature level
again.
Red / green slow ashing: No operating soft-
ware installed. Connect the amplier to the DSP
PC-Tool software and conrm the automatic up-
date of the operating system. You will nd the
latest version of the DSP PC-Tool software at
www.audiotec-scher.com.
Red / green fast ashing: The currently selected
sound setup memory is empty. A new setup has to
be loaded via the DSP PC-Tool software or switch
to a memory position with existing sound setup.

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.

signals and no MP3- or Dolby-coded digital audio
stream!
Note: In standard conguration the manual activa-
tion via an optional remote control is congured.
