LOW (12)
An active tone control (shelving type,
±
15 dB) that varies the low frequency boost or cut.
GRAPHIC SELECT (13)
The "in" position of this switch routes the signal through the graphic equalizer. The "out" position removes the
graphic equalizer from the signal path.
7-BAND GRAPHIC EQ (14)
A 7-band, two-and-one-half-octave graphic equalizer that provides 15 dB of boost or cut at each center frequency.
CROSSOVER BALANCE CONTROL (15)
Controls the relative levels of output signals from the crossover. Adjusting this control will only affect signals at
the High Range Output Jack and the Low Range Output Jack on the rear panel. All other output signals are
unaffected by this control.
MASTER VOLUME (16)
Controls the overall volume level of the system.
CROSSOVER FREQUENCY (17)
The frequency control varies the crossover frequency from 100 Hz to 1 kHz.
POWER LED/DDT™ INDICATOR (18)
The LED is green when the power switch is in the "on" position. During normal operation, this LED also acts as a
DDT™ indicator. The LED illuminates "red" when DDT™ power amp compression is taking place.
POWER SWITCH (19)
Used to turn AC mains power on or off.
CIRCUIT BREAKER (20)
This breaker is provided to limit the current to the power transformer, and thereby protect it from overheating and
possible destruction due to faulty conditions in the amplifier. The trip current value has been carefully chosen to
allow continuous power output performance, while still providing adequate protection for the power transformer.
Normally this breaker 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 or continuous operation at overload or clipping,
will cause the breaker to trip. If this occurs, 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, then simply pushing the button back in will
reset it after waiting a brief period of time to allow it to cool down. If the breaker trips instantly each time you
attempt to reset it, then the unit should be taken to a qualified service center for repair.
