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.
An
overcurrent
condition
is
monitored
permanently. If the output current to the
loudspeakers exceeds 50A the amplifier limits
power
dissipation
in
the
MOSFET
output
transistor to safe levels, protecting speakers and
the amplifier.
Mains voltage selection / fuse replacement
The following work should only be carried
!
out by a qualified technician in accordance
to highest electrical safety standards. Risk of
electric shock.
Replacing the fuse
The fuse must be replaced by a 6,3AT type
(5x20mm).
Never attempt to short the fuse
holder. Normally the fuse should never blow – if
it has, it is a sign of a serious fault condition.
Further investigation is needed.
