Dear Customer,
Congratulations on your purchase of this high-quality
BRAX product.
You may be interested to know that we have been working
now for 17 years in the development and production of
top-quality high-end hifi components.
Within just a few years, we have succeeded in giving the
BRAX brandname world wide recognition. Our efforts in
creating these quality products have also been rewarded
through the award of various honours by the major car
audio
magazines, not to mention numerous world wide
innovation
prizes.
In keeping with the tradition thus established, we have again
provided our new BRAX amplifiers with everything they
require in order to assume their rightful position as the pace-
setters in the market. Offering the maximum possible level
of engineering quality, they combine outstanding sound
reproduction, solid craftmanship and the noblest of materials
to provide a completely new dimension in individuality.
We are proud to offer you this high-end product MADE IN
GERMANY. and wish you many hours of enjoyment with
your new BRAX amplifier.

In order to maintain the quality of this product and ensure
safe operation, we recommend that our amplifiers be
installed by an authorized BRAX dealer. Installation by a
qualified and accredited technician will qualify you for our
special lifetime warranty. Your BRAX dealer will also
assist you in selecting the correct additional components
and in ensuring that proper consideration is given to all the
safety and sound-related aspects.
Important:
Before commencing installation, disconnect the car
battery at the negative terminal. Once again we would
urge you to have the installation work carried out by a spe-
cialist, as verification of correct installation and connec-
tion of the unit is a prerequisite for warranty cover of the
BRAX by AUDIOTEC FISCHER Germany.
1.
Install your amplifier at a dry location in the car where
there is sufficient air circulation to ensure adequate cooling
of the equipment. Also ensure that there is sufficient clearance
available for making the cable connections and operating
the controls.
2.
For safety reasons, the amplifier must be secured in a pro-
fessional manner. This is performed by means of four
fixing screws (see Fig. 2) screwed into a mounting surface
offering sufficient 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 con-
cealed in the double-skin trim panels/moldings.
