Audiotec Fischer HELIX V TWELVE DSP Bedienungsanleitung Seite 27

Initial start-up and functions
1 USB Input
Connect your personal
V TWELVE DSP using the provided USB cable. The
required PC software to configure this amplifier can
be downloaded from the Audiotec Fischer website
www.audiotec-fischer.com.
Please note: It is not possible to connect any USB
storage devices.
2 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 amplifier. Depending on the type of remote con-
trol, 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 provides 10 internal memory
locations for sound setups. The Control pushbutton
allows the user to switch between two memory po-
sitions. These can be defined in the DSP PC-Tool.
Pressing the button for five seconds completely
erases the internal memory. This is indicated by a
continuous red glowing and constant green flashing
of the Status LED.
Note: The memory locations one and two are de-
fined ex works. To manually switch between the set-
ups the button has to be pressed and held for one
second. Switching is indicated by a single red flash
of the Status LED. To switch between all internal
memory locations, optional accessories like the DI-
RECTOR display remote control or WIFI CONTROL
are required.
Attention: After erasing the setups from memory
the HELIX TWELVE DSP will not reproduce any
audio output.
4 Status LED
The Status LED indicates the operating mode of the
amplifier and of its memory.
Green: Amplifier is ready for operation.
computer to the
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 amplifier is overheated the internal tempera-
ture protection switches off the remote and signal
output until it reaches a safe temperature level
again.
Red / green slow flashing: No operating soft-
ware installed. Connect the amplifier to the DSP
PC-Tool software and confirm the automatic up-
date of the operating system. You will find the
latest version of the DSP PC-Tool software at
www.audiotec-fischer.com.
Red / green fast flashing: 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.
5 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
recommend to use optional accessories like
the DIRECTOR display remote control or 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.
6 Rem Out
We strongly recommend to use this output for turn-
ing on / off additional amplifiers that are connected
to the Line Output of the HELIX V TWELVE DSP.
This is essential to avoid any interfering signals.
