STEREO 2-WAY MODE
In 2-way stereo mode 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] & [5] I
NPUT GAIN Controls the INPUT level with +/- 12 dB of gain.
[9] & [15] LOW CUT Switch for selecting the 40 Hz high pass filter. An LED indicates
the selection.
[2] & [6] LOW/HIGH Selects crossover point between the LOW and HIGH outputs.
[10] & [16] X10 LED Indicates that the LOW/HIGH crossover frequency range is 450
Hz to 9.6 kHz.
[3] & [7] LOW OUTPUT Controls the Low Frequency output level with a range of -∞ to +6
dB.
[11] & [17] PHASE INVERT Switch for reversing the polarity on the Low Output. An LED indi-
cates the selection.
[4] & [8] H
IGH OUTPUT Controls the High Frequency output with a range of -∞ to +6 dB.
[12] & [18] PHASE INVERT Switch for reversing the polarity on the High Output. An LED indi-
cates the selection.
[14] STEREO LED indicating stereo mode operation.
MONO 3 -WAY MODE
In 3-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 3-way mode. LEDs are disabled for controls which are non-
functional in this mode.
[1] INPUT GAIN Controls the input level with +/- 12 dB of gain.
[9] L
OW CUT Switch for selecting the 40 Hz high pass filter. An LED indicates
the selection.
[2] LOW/MID Selects crossover point between LOW and MID frequencies.
[10] X10 LED Indicates that the LOW/MID crossover range is 450 Hz to 9.6 kHz.
[6] MID/HIGH Selects the crossover point between MID and HIGH frequencies.
[16] X10 LED Indicates that the MID/HIGH crossover frequency range is 450 Hz
to 9.6 kHz
[3] LOW OUTPUT Controls the LOW frequency output level with a range of -∞ to +6
dB.
[11] PHASE INVERT Switch for reversing the polarity on the Low Output. An LED indi-
cates that the phase is reversed.
[7] MID OUTPUT Controls the MID frequency output level with a range of -∞ to +6
dB.
[17] PHASE INVERT Switch for reversing the polarity on the Mid Output. An LED indi-
cates that the phase is reversed.
[8] HIGH OUTPUT Controls the HIGH frequency output level with a range of -∞ to +6
dB.
[18] PHASE INVERT Switch for reversing the polarity on the High Output. An LED indi-
cates that the phase is reversed.
[13] MONO LED indicating mono mode operation.
Note: There are no front panel differences between the 223 and the 223XL. Therefore the
223XL is shown below, representing both the 223 and the 223XL.
