Dear Customer,
congratulations on your purchase of this high power HELIX
DARK Blue FIVE amplifier.
Developed and designed with state-of-the-art technology it
highlights excellent manufacturing and best quality and
sets new standards with an excellent price/performance
ratio.
The DB FIVE features a 4-channel-section with an integra-
ted, variable active highpass frequency crossover for chan-
nel 1 and 2 and an active crossover with highpass, low-
pass and bandpass for channel 3 and 4. The amplifier can
be bridged for more connecting options.
Channel 5 is a mono bass channel with an integrated, varia-
ble active crossover for lowpass and integrated bass boost
(0 to +18dB at 45 Hz).
Based on the numerous capabilities the DB FIVE
also can be used in full active mode without passive
crossovers.
We wish you many hours of enjoyment with your new
HELIX amplifier.
Yours
AUDIOTEC FISCHER Team
General installation instructions for HELIX amplifiers
To find out how HELIX amplifiers work best for you, read this
manual carefully and follow the instructions for installation. We
guarantee that this product has been checked for proper functio-
ning before shipping.
Before you start installation, disconnect the car battery at the
minus pole. We would urge you to have the installation work car-
ried out by a specialist as verification of correct installation and
connection of the unit is a prerequisite for warranty cover of the
HELIX amplifier.
Install your amplifier at a dry location where there is sufficient air
circulation to ensure adequate cooling of the equipment. For
safety reasons, the amplifier must be secured in a professional
manner. This is performed by means of four fixing screws 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 - otherwi-
se these could be damaged. You should be aware of the fact that
such components may also be concealed in the double-skin trim
panels/mouldings.
General instruction for connecting the amplifiers
The HELIX amplifiers may only be installed in motor vehicles
which have a 12-volt minus pole connected to the chassis ground.
Any other system could cause damage to the amplifier and the
electrical system of the vehicle.
The plus cable from the battery for the complete 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 input of the car audio system.
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 prevent fraying.
Never lay the power supply cables adjacent to leads and lines
connecting other vehicle equipment (fan motors, fire detection
modules, gas lines etc.).
In order to ensure safe installation, use only high-quality connections
and materials. Ask your dealer for high quality accessories.
