4 OPERATION

4.1Indicators 4.1.1 On LEDs

Under normal operation, after the amp has started, the green power LEDs are permanently lit.

4.1.2 Signal / Protect LEDs (multifunctional)

The green Signal LEDs are illuminated when the voltage level at the output reaches approx. 4 V; this corresponds to a power of approx. 4 W into a 4 Ohm load.The channel signal LEDs are illuminated red when the amplifier is in Protect Mode (Mute), for example because of persistent DC-voltage at the outputs or overheating.

4.1.3 I-Out LEDs

The brightness is proportional to the output current in the channel. Output current of approx. 1 A lights up the LED at its lowest brightness level, while full brightness corresponds to the maximum rated current.

4.1.4 Clip LEDs

This LED indicates an overloading of the amplifier when the power output level is to high.
