Usb Input - HELIX DSP.3S General Instructions Manual

Initial start-up and functions
Nevertheless, there are use cases where it will
be necessary to directly connect input and output
ground or to tie both grounds together via a resistor.
Therefore the Ground lift switch has three positions:
- center position:
separated.
- left position: input and output ground tied
together.
- right position:
connected via 200 Ohms resistor.
7 Control pushbutton
The DSP.3S provides 10 internal memory locations
for sound setups. The Control pushbutton allows
the user to switch between two memory positions.
These 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 DSP.3S will not reproduce any audio output un-
til the device is updated via the DSP PC-Tool soft-
ware.
8 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.3S 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 off the remote and signal output
until it reaches a safe temperature level again.
Red / green slow flashing: No operating software

installed. Connect the signal processor to the
DSP PC-Tool software and confirm the automat-
ic update of the operating system. You will find
the latest version of the DSP PC-Tool software at
ground www.audiotec-fischer.com.
Red / green
sound setup memory is empty. A new setup has to
be loaded via the DSP PC-Tool software or switch
ground to a memory position with existing sound setup.

9 USB input

Connect your personal computer to the DSP.3S
using the provided USB cable. The required PC
software to configure this signal processor can be
downloaded from the Audiotec Fischer website
www.audiotec-fischer.com.
Please note: It is not possible to connect any USB
storage devices.

This multi-functional input is designed for HELIX
DSP.3S 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 first its functionality has to be defined in the
" Device Configuration Menu" of the DSP PC-Tool
software.
Attention: If the accessory product does not have
a NanoFit connector solely use the NanoFit adaptor
which is included in delivery for connection.
Line Output
11
8-channel pre-amplifier output for connecting po wer
amplifiers. The output voltage is 6 Volts max. Please
make sure that you always turn on / off external am-
plifiers 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 off 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.
