Protective circuit
The protective circuit is provided to prevent damage to the speakers and the amplifier. If it is activated, the
PROTECT
LED will light up:
1. Approximately one second after switching on (soft start).
2. If the amplifier is overheated, or if a short circuit has occurred at a speaker output, the
CLIP
LED of the corresponding channel
lights up. If this is the case or if the
PROTECT
LED lights up during the operation or if it is not extinguished after switching on, the
amplifier must be switched off and the cause for the defect needs to be eliminated.

Output modes
Each Kam KXR V2 power amplifier has different output modes.
Stereo mode
sends the signal from each channel to the corresponding audio output (e.g. channel A input > channel A output).
Bridge mode
sends both channels to one audio output only thus doubling the output voltage of the amplifier. Ensure that the
speaker connected to the single bridge output of the amplifier is able to handle this increased voltage and is the correct impedance.
Parallel mode
doubles the ouput current of the amplifier which increases the output impedance.
The Kam KXR150 V2 / KXR300 V2 / KXR600 V2 / KXR1000 V2 / KXR1500 V2 models are able to switch between Stereo mode and
Bridge mode.
The Kam KXR1500 V2 and KXR2000 V2 models are able to switch between Stereo, Bridge and Parallel modes.

the mains cable supplied is of a heavier
guage than standard IEC cables. Only use the cable supplied or one of the same specification.
Failure to do so may result in
permanent damage to the amplifier.
