Filter Quality
When selecting a
Notch
,
Band-pass
,
High-pass
, or
Low-pass
filter, you can adjust the quality of the frequency
response. For the
Notch
and
Band-pass
filters, this essentially adjusts the width of the “notch” or passband.
For
High-pass
and
Low-pass
filters, this adjusts the “slope” of the cutoff frequency. Keep in mind that this
setting has no effect on the
Flat
or
1Khz
filters.
Frequency
The Frequency adjustment section allows you to select the cutoff frequency in the case of a
High-pass
or
Low-
pass
filter, or the center frequency in the case of a
Band-pass
or
Notch
filter. A digital readout is provided
which shows the exact frequency selected. Just like the
Filter Quality
setting, the
Frequency
setting has no
effect on the
Flat
or
1Khz
filters.
Master Control Panel
Whenever any of the small buttons is activated beneath each individual control, it becomes “ganged” with the
Master Control panel. This way you can adjust many (or all) channels at the same time with just the one Master
Control.
