Using the High and Low Pass Filters
1. At the bottom of the SCF/FILTER/EQUALIZER panel,
press the FILTER DISP button to switch the four sets of
GAIN, FREQ and Q controls to the 2-band filter section.
Controls on the left side of the panel now adjust the high pass
filter, and controls on the right side adjust the low pass filter.
The two bands default to provide constant Q equalisation.
2. Turn on the master FILTER ON button.
3. To change the two bands to high and low pass filters, use
the EQ type buttons.
The TYPE boxes on the Main display update to show Hi-P or
Lo-P respectively.
4. Use the FREQ rotary control to set the roll-off frequency
for the filter.
Frequency may be set from 20Hz to 20kHz, and the value is
shown beneath the front panel control and in the FREQ box on
the Main display.
5. Use the Q/SLP rotary control to set the slope of the filter.
The slope may be set to 6dB per octave, 12 dB per octave or
18dB per octave and is shown in the Q box on the Main
display.
6. Press either of the two OFF buttons to switch the
individual filters out of circuit.
The two filter bands may be used for filtering, shelving EQ or
constant Q operation by adjusting the EQ type selection
buttons. You can also set each band independently. For
example, to keep your high pass filter, but use the other filter
band as an extra band of EQ.
