Protection circuits
HÄNDEL provides comprehensive protection for
both the amplifier and your loudspeakers,
including faults that may occur in your source
components.
If the unit is operated at high playback levels
with
insufficient ventilation, the internal
temperature may become too high for safe
operation. In this case the front-panel status LED
will change colour from static blue to red. If the
LED is appears totally red, the amplifier will shut
down, the LED will blink until the unit has cooled
down sufficiently.
Likewise, if the surveillance circuit detects the
presence of DC (LED = blinks green) at the output
terminal, the amplifier will shut down too.
Unallowable DC voltages can origin from the
source component or the HÄNDEL amplifier itself.
To isolate the source of the problem, disconnect
the audio input cable from the HÄNDEL amplifier
before proceeding any further.
If the error message persists, the amplifier hasn’t
cooled down sufficiently, or the unit itself is faulty.
If the DC error only shows up, when the source is
connected, the source component is faulty. In
both cases consult your dealer.
