The Q (bandwidth) can be set to values from 0.27 through 8.7, in 30 steps.
For the HM and LM bands Q can be set only if 'bell' is selected.
HM, high-mid frequency, and LM, low-mid frequency: Q = 0.27 through 8.7,
in 30 steps.
Slope setting for the high- and low-cut filters, selectable from 12, 18, and
24 dB/octave (key toggles 12, 18, 24, 12...).
Cutoff frequency adjustment for the high- and low-cut filter: 20 Hz through
20 kHz, in 120 steps.

On/off function for the notch filter.

notch q
The notch filter's Q is selectable from two fixed values; W (wide, Q=2), and
N (narrow, Q=10).
The EQ, HI CUT and LO CUT hardware keys in the CHANNEL PROCESSING
note
area can be used for activating or deactivating the complete EQ, high- and
low-cut filter sections of a channel (or a gang of channels) selected with LINK/
SEL, in addition to the individual on/off keys described above.
This view is the same as with mono or stereo channels. Please note that the
equalizer settings applied here will be valid for all surround signal legs except
the LFE.
If an EQ setting has been made on a 5.1 surround channel, the normal Viston-
ics EQ display shows in small characters which signal legs are different from
the others (e.g. 'Lf'), as shown left.
If one or more of the signal legs must be adjusted differently from others –
such as boosting HF in the center channel only, the CHANNEL VIEW has to be
selected. Then all the separate EQ settings for 'Front', 'Center', 'LFE' and
'Rear' are accessible.
