Dear Customer,

Congratulations on your purchase of this high-quality BRAX product. The MultiController high-
lights best quality, excellent manufacturing and state-of-the-art technology. To find out how the
MultiController can be made to work best for you, read this manual carefully and follow the instruc-
tions for installation. We guarantee that this pruduct has been checked for proper functioning befo-
re shipping.
We wish you a lot of fun with the MultiController.
Yours, the AUDIOTEC FISCHER team.

Installation instructions

Before you start installation, disconnect the car battery at the minus pole. We would urge you to
have the installation work carried out by an authorized specialist as verification of correct installa-
tion and connection is a prerequisite for warranty cover of the Multicontroller.
Install your amplifier at a dry location in the car. For safety reasons, the Multicontroller must be
secured in a proffessional manner. For this use the attached four fixing screwes and fix them into a
mounting surface offering sufficient 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 tank located behind the mounting surface –
otherwise these could be demaged. You should be aware of the fact that such components may
also be concealed in the double-skin trim panels/ mouldings.
Installation
Two amplifiers can be connected on the MultiController. Connect output power cables up to 35
sqmm/ gauge 2 (AMP 1 – Output/AMP 2 – Output) between mainboard unit and amplifiers. Tighten
the screws firmly. In the case of using fans connect the cables between mainboard and cooling fans
(AMP 1 – Fan/AMP 2 – Fan). Fix the temperature sensors tight to the heatsink of the amplifier to
ensure good contact. Now connect the wires to the mainboard (AMP 1 – Temp/AMP 2 – Temp).
First connect the data cable to the display and then to the mainboard (Output Controller Display).
Be sure that the connection are correct (white and brown). Connect input battery cables to
the mainboard (AMP 1 – Battery input/AMP 2 – Battery input). A fuse should also be provided
at a max. distance of 30 cm from the battery. The amperage rating of the fuse is calculated
from the max. total current input. Then tighten grounding (Ground) and remote switch wire (Remo-
te). For the separate display brightness use the "Lights" input. This input is connected with a wire
that supplies 12 V only when the lights are on.
Connecting the display
Connect the red wire at + 12 V, the black to ground and the white to remote. Make sure that all
cables are connected in a proper manner. Switch on remote and enjoy your Multicon-
troller performance!

Troubleshooting:

Mainboard is not running at all.
1. Check all the cables – data cable must be connected so that white wire is near to AMP 1 side
and brown wire is near to AMP 2 side.
2. Check the display unit is powered on and showing some values.
3. Check the fuse is good and well inserted in the fuse holder.
4. Check the refresh rate set in display unit – it too long you may want to set it shorter.
Fan is still running, even if temperature is lower than over-temperature set.
1. Check the temperature being shown on display – if Hot then check the sensor cables and tighten
them firmly.
Fan is not running.
1. Check the grounding wire of fan is well grounded and the current input to the fan is not higher
than specified.
2. Check the temperature sensed is higher or equal to over-temperature setting.
3. Check the appropriate Fan 1/2 output has its own AMP 1/2 Battery input supplied from battery.
