FRONT PANEL FEATURES
DDT™ ACTIVE LED INDICATOR (1)
[lluminates when DDT™ compression is taking place. This LED becomes a clip indicator when the rear panel
DDT™ ENABLE/DEFEAT switch is in the DEFEAT position.
OPERATION NOTE:
It is normal for the DDT™ LED(s) to flash occasionally during amplifier operation. If the
LED(s) remain on continuously, additional headroom is needed. In some cases, this may mean that the
particular application requires a more powerful amplifier.
POWER LED INDICATOR (2)
Illuminates when AC power is supplied to the amplifier.
POWER SWITCH (3)
Depress to the "ON" position to turn the amplifier on.
CIRCUIT BREAKER (4)
This breaker is provided to limit the current to the associated power transformer and protect it from
overheating and possible destruction due to fault conditions in the amplifier. The trip current values have
been carefully chosen to allow continuous power output performance while still protecting the power
transformer. Normally, these breakers should not trip unless there is a fault in the amplifier circuitry that
draws excessive mains current. However, abnormal conditions such as a short circuit on either or both
channels, or continuous operation at overload or clipping (especially into 4 ohm load) will cause the breaker
to trip. If this occurs, turn the power switch off, then simply reset the breaker and correct the cause of the
overload.
When tripped, the button on the breaker will be outward nearly 1/2" and can be reset by
pushing inward. A normal reset button length is about 1/4". If this "thermal" type breaker does
trip, simply pushing the button back in will reset it, after waiting a brief period of time to allow
it to cool down. REMEMBER, ALWAYS TURN THE POWER OFF BEFORE RESETTING
THE BREAKER. If the breaker trips instantly each time you attempt to reset it, the unit
should be taken to a qualified service center for repair.
OPERATION NOTE: This unit is equipped with automatic resetting thermal protection. If extremely high
operating temperatures cause the protection circuit to engage, the unit will shut down. Once it has cooled
sufficiently, the protection circuit will disengage and the amplifier will be re-enabled. Continued thermal
cycling indicates a load problem exists (shorted cable or the total speaker load is too low), or there is
inadequate ventilation.
