General installation instructions for HELIX-
components
To fi nd out how this HELIX amplifi er works best
for you, read this manual carefully and follow the
instructions for installation. We guarantee that this
product has been checked for proper functioning
before shipping.
Before you start installation, disconnect the
car battery at the minus pole. We would urge
you to have the installation work carried out by a
specialist as verifi cation of correct installation and
connection of the unit is a prerequisite for warranty
cover of this HELIX product.
Install your HELIX PP20 DSP at a dry location
where there is suffi cient air circulation to ensure
adequate cooling of the equipment. For safety
reasons, the amplifi er must be secured in a pro-
fessional manner. This is performed by means of
the fi xing screws screwed into a mounting surface
offering suffi cient retention and stability.
Before drilling the holes for the screws, carefully
examine the area around the installation position
and make sure that there are no electrical cables
or components, hydraulic brake lines or any part
of the petrol tank located behind the mounting
surface - otherwise these could be damaged. You
should be aware of the fact that such components
may also be concealed in the double-skin trim pa-
nels/mouldings.
the research and development of audio products
this Plug & Play amplifi er is another milestone
concerning sound quality.
We wish you many hours of enjoyment with your
new HELIX PP20 DSP.
Yours,
AUDIOTEC FISCHER
General instruction for connecting the HELIX
PP20 DSP amplifi er
The HELIX PP20 DSP may only be installed in
motor vehicles which have a 12-volt minus pole
connected to the chassis ground. Any other sy-
stem could cause damage to the amplifi er and the
electrical system of the vehicle.
Please do only use the provided HELIX cable for
the connection of the PP20 DSP. The use of other
or similar cables can result in the damage of the
amplifi er, of the head unit / radio or the connected
loudspeakers!
The fuse of the HELIX cable must only be re-
placed by an identical fuse (20A) in order to
avoid the damage of the amplifi er. Moreover,
the use of fuses with higher Ampere values
can result in serious consequential damages
and losses.
Install the cabling in a manner which precludes
any danger of the leads being exposed to shear,
crushing or rupture forces. If there are sharp
edges in the vicinity (e.g. holes in the bodywork)
all cables must be cushioned and protected to pre-
vent fraying. Never lay the power supply cables
adjacent to leads and lines connecting other vehi-
cle equipment (fan motors, fi re detection modules,
gas lines etc.).
