Main Circuit Breaker
Your amplifier is supplied with two heavy-duty magnetic
circuit breakers/power switches. If power to your amplifier
is interrupted, inspect the circuit breaker on the rear of the
unit. If the circuit breaker is in the off position you may
reset it to the on position to restore AC power. If the circuit
breaker immediately trips to the off position, unplug the
amplifier from the AC power source and contact the ATI
Service Department.
WARNING: Always turn off the amplifier and unplug the power cord
before making any electrical connections.
Protection Circuitry
Your ATI amplifier uses an advanced optically coupled
protection circuit that does not require fuses and is com-
pletely isolated from the audio path. In the event that the
amplifier senses a shorted speaker wire or other fault condi-
tion, the protection circuit will engage shutting down the
output and will sample the state of the amplifier every 7
seconds (nominal). The output will remain cut off as long
as the fault condition exists. The amplifier will return to
normal operation when the fault condition (short circuit,
etc.) is removed/repaired.
If this should occur, first check all speaker wire connec-
tions, both at the speakers themselves and at the speaker
terminals on the rear of the amplifier to verify that none of
the strands from any channel touch any other channel and
that none of the strands from a "positive" terminal touch
those from a "negative" terminal. Even a single stray wire
may cause the amplifier to go into the protection mode.
After checking all speaker connections, turn the unit back
on. If it continues to turn off, check your speakers to verify
they are operating properly. If all other potential sources of
trouble check out properly, please contact ATI for further
assistance and information.
