4-5 Connectors for a BRAX Power Stabilizer
By connecting a BRAX Power Stabilizer peak loads in the power supply will be eliminated. Thus, the amplifier has always
enough power for a perfect performance.
Equipment and control units
6 Signal inputs
The amplifier has RCA connectors for RCA cables that can be connected with the pre-amplifier output of the line outputs of
the headunit or with a pre-amplifier. The connectors are gold-plated to ensure a better signal transmission.
7 Balanced signal inputs
The amplifier BRAX Matrix X4 has four balanced signal inputs which account for the elimination of distortions on the signal
path.
8 Level controls for input sensitivity
These controls can be used to match the input sensitivity of the individual channels to the output voltage of the connected
head unit. These controls are no volume controls and are solely intended for the purpose of sensitivity trimming. The con-
trol range extends from 600 mV to 8,0 V.
9 Loudspeaker terminals
To connect the speaker cables. Never connect the loudspeaker cables with the car chassis ground. It damages your
amplifier. All speaker systems must be connected in-phase, this means plus to plus and minus to minus. Inverting plus and
minus will result in the loss of bass rendition. The positive terminal is marked on most speakers.
10 Stereo/Bridged/Mono selector
To select the mode of the amplifier.
Stereo: Select the STEREO MODE for using the channels A/B or C/D in the 2-channel mode. The respective LED (STE-
REO) lights up blue.
