Owner`s manual

1. LIMIT
This indicator lights when the amplifier enters clipping and the internal limiter is activated. Short-term
indication is permissible while a continuous lit LED signals that reducing the overall volume is recommen-
ded to avoid the connected loudspeaker systems from being damaged by overload conditions.
2. SIGNAL INDICATOR
This indicator lights when an output signal is present. In case of short-circuited speaker cabling or one of
the amplifier’s protection functions is engaged the indicator is off, showing that there is no signal outputted.
3. POWER ON Indicator
This LED lights when the appliance’s power switch has been engaged. If the indicator does not light after
engaging the power switch, either the amplifier is not connected to the mains or the internal mains fuse
has been blown and it needs to be replaced.
4. PROTECT
If this indicator lights during operation, one of the amp’s internal protection functions against thermal
overload, short-circuit, or the occurrence of HF at the output has been engaged. The cause that let the
amplifier enter the protection mode – e. g. a short-circuited speaker cable – has to be eliminated. In case
of thermal overload you have to wait until the power amplifier returns into normal operation mode.
5. POWER Switch
Using the POWER switch you turn the amplifiers power on. To eliminate unwanted noise and knacks in
the connected speaker systems, loudspeaker output switching is performed delayed via relays. An initial
current inrush limiter prevents the mains fuse from being blown during power-on.
