Reset Button to reset all de-esser parameters of the current channel at once.
Each channel has a parametric four-band equalizer. If the user has no access
permission to the EQ parameters, the CHAN - EQ page is not displayed.
Graph
The red graph represents the EQ's current frequency response curve, cumu-
lated from all filters.
Clicking on one of these edit buttons selects one of the four frequency
bands for adjustment. The corresponding, exact Gain, Frequency, and Q
(bandwidth) values appear in the fields above the rotary encoders and can be
adjusted. The current frequency response curve is displayed in the EQ screen.
Gain The gain (boost/cut value) of the selected band is displayed in dB and can be
adjusted in a ±18 dB range with the rotary encoder below the field.
The center frequency of the selected band is indicated by a vertical, dashed
line, as well as displayed in Hz/kHz. It can be adjusted from 20 Hz to 20 kHz
with the rotary encoder below the field.
The Q factor of each band is displayed as a plain number and can be adjusted
from 0.27 (wide) to 8.7 (narrow) with the rotary encoder below the field.
Should a very high-Q (i.e. narrow) and/or very high/low gain band-pass (peak)
or band-stop (notch) filter be required, this can be realized by tuning two or
more of the EQ bands to the same frequency and selecting appropriate Q and
Gain values.
A click on the Gain button displays the gain values of all four EQ bands in
the fields above the rotary encoders for adjustment; the center frequencies
are indicated by four vertical, dashed lines.
ON Button to enable/disable the complete EQ/filter section of this channel; high-
lighted if on. If off, the graph gets grayed out.
