CONTROL PANEL: SWITCHES AND ADJUSTMENTS
1.
CH A LEVEL (0.3V - 5V): CH A
input sensitivity. Set the knob to position 1. Use a CD as a source
and increase the source volume until you hear distortion, then lower it slightly to eliminate distortion. Increase the
amplifier CH A LEVEL to optimize the output signal without distortion.
2.
CH B LEVEL (0.3V - 5V): CH B
input sensitivity. Set the knob to position 1. Use a CD as a source
and increase the source volume until you hear distortion, then lower it slightly to eliminate distortion.
Increase the amplifier CH B LEVEL to optimize the output signal without distortion.
3.
CH C LEVEL (0.3V - 5V): CH C
input sensitivity. Set the knob to position 1. Use a CD as a
source and increase the source volume until you hear distortion, then lower it slightly to eliminate distortion.
Increase the amplifier CH C LEVEL to optimize the output signal without distortion.

knob
(see section 5)
.
5.
HI PASS XOVER (50 Hz - 500 Hz):
Adjustment of the channel A high-pass filter cut-off frequency. By turning the
knob it is possible to vary the cut-off frequency from 50 Hz to 500 Hz @ 12dB/Oct.
6.
MULTIPLIER X1 - X10:
Select
X1
for a filter frequency range of 50 Hz-500 Hz for the channel A crossover.
Select
X10
for a filter frequency range of 500 Hz - 5 kHz for the crossover.
7.
PASS MODE (HI-BAND - FULL):
Switch to select channel B filter type. Select
FULL
to get a full range
output signal. Select

(see section 8)
. Select
BAND
to get an output signal to
drive a MIDRANGE
(see section 8/9)
.
8.
HI PASS XOVER (50Hz - 1kHz):
Adjustment of the channel B high-pass filter cut-off frequency. By turning the
knob it is possible to vary the cut-off frequency from 50 Hz to 1KHz @ 12dB/Oct.
9.
LO PASS XOVER (250Hz - 5kHz):
Adjustment of the channel B low-pass filter cut-off frequency. By turning the
knob it is possible to vary the cut-off frequency from 250Hz to 5KHz @ 12dB/Oct.
