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
3 flashes
4 flashes
5 flashes
Possible Condition
Excessive current draw
Excessive temperature
Excessive DC at input

Course of Action
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.
Allow the amplifier to
cool, and increase venti-
lation. If the problem
persists, please call the
factory.
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.
