Power Switch ON/OFF

Power LED
The LED will light in green when the CA is switched on.
PROT, CLIP, SIGNAL LEDs
 PROT: The LED will light in red when the amplifier is in protection mode. Switch off the device and
find out what the problem is. The amplifier is protected against overheating, overload, short
circuit, etc. Decrease the source signal level and/or improve air circulation in the room where
the CA is installed.
 CLIP: When the LED lights in red, it indicates distortion. In this case, decrease your source signal
level until the LED turns off. Please keep in mind that the amplifier itself cannot correct any
distortion.
 SIGNAL: When the LED lights in green, it means that the CA is operating within its safety limits.
