Connection of the Speaker Cables
7
Important!
Never connect the speaker cables to the vehicle chassis.
This can destroy your amplifier. Ensure that all the speaker
systems are connected in-phase, i.e. plus to plus and minus
to minus. The positive terminal is indicated on most spea-
kers. In addition, the amplifiers may be operated in both
the stereo and mono (bridge) modes (see Fig. 7).
The mono/stereo selector switch is located at the bottom
and can be operated once the metal cover has been remo-
ved (see Fig. 15). The function of the switch is described
on a label at the bottom of the amplifier.
In addition to this stereo/mono capability, the BRAX
amplifier modules can also be connected in the „tri“ mode,
i.e. they can operate two stereo speakers from one pair of
channels (left and right) and at the same time output to a
third speaker in the mono mode (see Fig. 6). For this, the
selector switch at the bottom of the unit must be set at
„Stereo“.
