4.2 Indicators
4.2.1 On LEDs
Under normal operation, after the amp has started, the green power LEDs are
permanently lit.
4.2.2 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 Pro-
tect Mode (Mute), for example because of persistent DC-voltage at the outputs
or overheating.
