Error Codes
In the event of a problem, the power status indicator (2) will flash error code(s) in
red. Errors are identified by a sequence of 3, 4, or 5 flashes. There is a pause
between codes, and in the case where there is only one error code, the same
code is repeated.
Diagnostic Code
Possible Condition
Course of Action
3 flashes
Excessive current draw
Check loudspeaker and
cables for short circuits.
If you are driving more
than one loudspeaker
per channel, check that
the combined load does
not drop below 2 Ohms.
The power breaker
switch must be shut off
to reset the fault condi-
tion.
4 flashes
Excessive temperature
Allow the amplifier to
cool, and increase venti-
lation. If the problem
persists, please call the
factory.
5 flashes
Excessive DC at input
Check the preamplifier
output and source out-
puts for excessive DC
voltage.
If you are using a vacuum
tube preamplifier, use
only the single-ended
inputs, as they are
capacitor coupled.
