ConnECtionS, CONTROLS, AND INDICATORS:

1
CHANNEL A / CHANNEL B
Volume controls for Channels A and B. Always set the volumes to minimum before turning the equipment on
or off. In bridge mode, the volume of the power amplifier is controlled by the volume control for Channel A.
2
POWER LED
Lights up once the speaker system is switched on and properly connected to the power mains.
3
SIGNAL LED A / B
The signal LEDs for Channels A and B light up as soon as there is an audio signal on the respective channel.
4
CLIP LED A / B
Lights up if the power amplifier is operating in the clipping range. Brief flashing is not critical. Permanent
illumination should be avoided by reducing the volume (volume control 1), because otherwise distortion
can result, which can have a negative influence on the sound on the one hand and, on the other, can cause
damage to the connected speakers.
5
PROTECT LED A / B
Lights up after power-on as long as the power-on delay is active. After the Protect LED goes out, the power
amplifier is ready for operation.
The Protect LED lights up when one of the power amplifier protection circuits is active. To protect the power
amplifiers and the connected speakers, the speaker outputs are deactivated in protect mode. Once the
source of the trouble has been eliminated (e.g., overloading or a short circuit at the speaker output), after a
short time, the power amplifier returns to normal status, the Protect LED goes out, and the speaker outputs
are reactivated. If the Protect LED does not go out after a short time even if all inputs and outputs have been
disconnected, there is an internal fault. In this case, turn off the power amplifier, disconnect it from the power
mains, and hand it over to an authorised service centre.
