FRONT PANEL FEATURES:

CHANNEL 1 LEVEL CONTROL (1)

Controls the signal level of the Channel 1 input.

CHANNEL 2 LEVEL CONTROL (2)

Controls the signal level of the Channel 2 input.

CHANNEL 3 LEVEL CONTROL (3)

Controls the signal level of the Channel 3 input.

LOW EQ CONTROL (BASS) (4)

Active equalization control that adjusts the low frequency response. Clockwise rotation boosts lows while counter-
clockwise rotation provides a cut (reduction) of the low frequencies (

±

10 dB).

HIGH EQ CONTROL (TREBLE) (5)

Active equalization control that adjusts the high frequency response. Clockwise rotation boosts highs while counter-
clockwise rotation provides a cut (reduction) of the high frequencies (

±

10 dB).

CONTOUR SWITCH (6)

The "in" position of this switch provides 6 dB boost at 100 Hz and 10 kHz. The "out" position removes boost from the
system.

MASTER (7)

Controls the overall volume level of the system.

POWER ON LED (8)

Indicates when AC power is being supplied to the unit.

SPS™ COMPRESSION ACTIVE LED (9)

Illuminates when SPS™

 

circuitry is active. SPS™

 

eliminates power amplifier clipping.

ACTIVITY (SIGNAL PRESENT) LED (10)

Indicates signal presence at amplifier output. Illuminates when output is approximately 35 dB below full power.

CHANNEL 1 LED (11)

Indicates activity on Channel 1 mute line. Illuminates when signal is present on Channel 1 or when Mute 2 terminal is
shorted to ground.

PAGE LED (12)

Indicates activity on Page mute line. Illuminates when signal is present on Page input or when Mute 1 terminal is
shorted to ground.

POWER SWITCH (13)

Depress to "on" position to turn on.
