In
Channel One and Channel Two functions are identical in the stereo mode. LEDs are disabled for controls which are
[1] | & [5] | INPUT 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 |
|
|
| dB. |
[11] & [17] | PHASE INVERT | Switch for reversing the polarity on the Low Output. An LED indi- | |
|
|
| cates the selection. |
[4] | & [8] | HIGH OUTPUT | Controls the High Frequency output with a range of |
[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
[1] | INPUT GAIN | Controls the input level with +/- 12 dB of gain. |

[8] | HIGH OUTPUT | Controls the HIGH frequency output level with a range of |
|
| 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. |
