General instructions

General installation instructions for HELIX
components
To prevent damage to the unit and possible injury,
read this manual carefully and follow all installation
instructions. This product has been checked for
proper function prior to shipping and is guaranteed
against manufacturing defects.
Before starting your installation, disconnect
the battery's negative terminal to prevent
damage to the unit, fire and / or risk of injury. For
a proper performance and to ensure full warranty
coverage, we strongly recommend to get this prod-
uct installed by an authorized HELIX dealer.
Install your HELIX DSP ULTRA in a dry location
with sufficient air circulation for proper cooling of the
equipment. The signal processor should be secured
to a solid mounting surface using proper mounting
hardware. Before mounting, carefully examine the
area around and behind the proposed installa-
tion location to insure that there are no electrical
cables or components, hydraulic brake lines or any
part of the fuel tank located behind the mounting
surface. Failure to do so may result in unpredictable
damage to these components and possible costly
repairs to the vehicle.
We wish you many hours of enjoyment with your
new HELIX DSP ULTRA.
Yours,
AUDIOTEC FISCHER
General instruction for connecting the HELIX
DSP ULTRA signal processor
The HELIX DSP ULTRA signal processor may only
be installed in vehicles which have a 12 Volts nega-
tive terminal connected to the chassis ground. Any
other system could cause damage to the signal pro-
cessor and the electrical system of the vehicle.
The positive cable from the battery for the entire
sound system should be provided with a main fuse
at a distance of max. 30 cm from the battery. The
value of the fuse is calculated from the maximum
total current draw of the car audio system.
Use only the provided connectors for connec-
tion of the HELIX DSP ULTRA. The use of other
connectors or cables can result in damage of
the signal processor, the head unit / radio or the
connected amplifiers / loudspeakers!
Prior to installation, plan the wire routing to
avoid any possible damage to the wire harness.
All cabling should be protected against possible
crushing or pinching hazards. Also avoid routing
cables close to potential noise sources such as
electric motors, high power accessories and other
vehicle harnesses.
