Initial start-up and functions

1 USB Input

Connect your personal
V EIGHT DSP MK2 using the provided USB cable.
The required PC software to configure this amplifier
can be downloaded from the Audiotec Fischer web-
site 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 EIGHT DSP MK2 accessory products like a re-
mote control which allows to adjust several fea-
tures of the amplifier. 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 EIGHT DSP provides 10 internal memory lo-
cations 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
setups 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 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 V EIGHT DSP MK2 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 EIGHT DSP MK2
is equipped with protection circuits against over-
and undervoltage as well as overheating. Please
check for connecting failures such as short-circuits
or other 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.
