HELIX DSP-3 - PC Connectivity and Output Connections

18
Initial start-up and functions
- right position: input and output ground
connected via 200 Ohms resistor.

Control pushbutton
The DSP.3 provides 10 internal memory locations
for sound setups. The Control pushbutton allows
the user to switch between two memory positions.
These can be dened in the DSP PC-Tool.
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. Switch-
ing is indicated by a single red ash of the Status
LED. To switch between all internal memory loca-
tions, the optionally available DIRECTOR display
remote control or the HELIX WIFI CONTROL is
recommended.
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.
Attention: After erasing the setups from memo-
ry the HELIX DSP.3 will not reproduce any audio
output.

Status LED
The Status LED indicates the operating mode of the
signal processor and of its memory.
Green: DSP is ready for operation.
Orange: Power Save Mode is active.
Red: Protection Mode is active. This may have dif-
ferent root causes. The HELIX DSP.3 is equipped
with protection circuits against over- and under-
voltage as well as overheating. Please check for
connecting failures such as short-circuits or other
wrong connections.
If the DSP is overheated the internal temperature
protection switches o󰀨 the remote and signal output
until it reaches a safe temperature level again.
Red / green slow ashing: No operating software
installed. Connect the signal processor to the
DSP PC-Tool software and conrm the automat-
ic update 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.

USB input
Connect your personal computer to the DSP.3
using the provided USB cable. The required PC
software to congure this signal processor can be
downloaded from the Audiotec Fischer website
www.audiotec-scher.com.
Please note: It is not possible to connect any USB
storage devices.
11
Control Input
This multi-functional input is designed for HELIX
DSP.3 accessory products like a remote control
which allows to adjust several features of the signal
processor. 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.
12
Line Output
8-channel pre-amplier output for connecting po wer
ampliers. The output voltage is 6 Volts max. Please
make sure that you always turn on / o󰀨 external am-
pliers using the remote output of the signal proces-
sors Power Input. Never directly control the external
amps by a signal from the ignition switch of your
car! Additionally this output will be turned o󰀨 when
the “Power Save Mode” of the signal processor is
active. The outputs can be assigned to any of the
inputs as desired using the DSP PC-Tool software.
