STEREO 3-WAY MODE
In 3-way stereo operation the controls are marked BELOW the horizontal blue line.
Channel One and Channel Two functions are identical in the stereo mode. LEDs are disabled for controls which are non-
functional in this mode.
[1] & [7] INPUT GAINControls the INPUT level with +/- 12 dB of gain.
[13] & [20] LOW CUTSwitch for selecting the 40 Hz high pass filter. An LED indicates the selec-
tion.
[2] & [8]LOW /MIDSelects crossover point between LOW and MID frequencies.
[14] & [21]X10 LEDIndicates that the LOW/MID crossover frequency range is 450 Hz to 9.6 kHz.
[3] & [9]MID/HIGHSelects crossover point between MID and HIGH frequencies.
[4] & [10]LOW OUTPUTControls the Low Frequency output level with a range of -° to +6 dB.
[15] & [22] PHASE INVERTSwitch for reversing the polarity on the Low Output. An LED indicates the
selection.
[5] & [11] MIDOUTPUTControls the Mid Frequency output with a range of -° to +6 dB.
[16] & [23] PHASE INVERTSwitch for reversing the polarity on the Mid Output. An LED indicates the
selection.
[6] & [12]HIGH OUTPUTControls the High Frequency output with a range of -° to +6 dB.
[17] & [24] PHASE INVERTSwitch for reversing the polarity on the High output. An LED indicates the
selection.
[19]STEREOLED indicating stereo mode operation.
MONO 4 -WAY MODE
In 4-way mono operation the controls are marked ABOVE the horizontal blue line. Front panel controls not described in
this section are not active in mono 4-way mode. LEDs are disabled for controls which are non-functional in mono 4-way
mode.
[1]INPUT GAINControls the input level with +/- 12 dB of gain.
[13] LOW CUTSwitch for selecting the 40 Hz high pass filter. An LED indicates the
selection.
[2]LOW /LOW -MIDSelects crossover point between LOW and LOW-MID frequencies.
[14]X10 LEDIndicates that the LOW/LOW-MID crossover frequency range is 450 Hz to
9.6 kHz.
[3]LOW -MID/HIGH-MIDSelects the crossover point between LOW-MID and HIGH-MID frequencies.
[9] HIGH-MID/HIGHSelects the crossover point between HIGH-MID and HIGH frequencies.
[4]LOW OUTPUTControls the LOW frequency output level with a range of -° to +6 dB.
[15]PHASE INVERTSwitch for reversing the polarity on the Low Output. An LED indicates the
selection.
[5]LOW -MIDOUTPUTControls the LOW-MID frequency output level with a range of -° to +6 dB.
[16]PHASE INVERTSwitch for reversing the polarity on the Low-Mid Output. An LED indicates
the selection.
[11] HIGH-MIDOUTPUTControls the HIGH-MID frequency output level with a range of -° to +6 dB.
[23]PHASE INVERTSwitch for reversing the polarity on the High-Mid Output. An LED indicates
the selection.
[12]HIGH OUTPUTControls the HIGH frequency output level with a range of -° to +6 dB.
[24]PHASE INVERTSwitch for reversing the polarity on the High Output. cates An LED indi
the selection.
[18]MONOLED indicating mono mode operation.
