Four fully parametric bands are provided on the Vista. Each band, which
can be switched in and out independently, extends from 20 Hz to 20 kHz,
with a ±18 dB gain range. The EQ features a psycho-acoustically corrected
frequency response for high frequencies, similar to well-known analog
EQ designs. The two mid-bands can be switched between constant-Q and
constant-range modes. The high and low frequency bands can be switched to
shelving mode. A second EQ type is available (defined by the configuration
currently loaded) that features an additional Notch filter.
Also available is a BSS
masters and auxiliaries. The graphic EQ may be shown and adjusted by 30 of
the faders when selected with a single desk key. As soon as any other control
except a fader or a channel mute key is touched or operated, fader operation
is immediately cancelled and switches back to normal mode. The FaderGlow
colour of these 30 faders will change to red, making it unmistakably clear that
currently the faders are dedicated to the graphic EQ function. The Vistonics
icon of the channel with the EQ on the faders is highlighted, all others are
blanked.
Both the graphic and the parametric EQs can be used individually or simul-
taneously, for all or specific channels only; the current setup is depending on
the configuration currently loaded.
Filters Low-cut and high-cut filters are provided, with cutoff frequencies that are
variable between 20 Hz and 20 kHz, and slope selections of 12, 18, or 24 dB/
octave.
In addition, an analog low-cut filter with a cutoff frequency of 75 Hz and a
slope of 12 dB/octave is available in the D21m Mic/Line preamplifier.
The Vista standard dynamics processing consists of four parts:
Limiter, Compressor, Expander, and Gate.
To avoid pumping and modulation, the dynamics processing sections feature
high sampling rate transient detection. Distortion artifacts are minim ized
through selectable, program-dependent attack and release times. The Vista's
dynamics feature a side-chain input that can be used with or without HP/
LP filters. A unique 'look forward' function is also featured. If desired, this
allows the entire transient portion of a waveform to be affected when using
the limiter/compressor or to be passed when the expander/gate is used.
Sometimes the dynamics processing can be utilized in a more pronounced
way, i.e., as an effect itself. For this purpose the 'vintage dynamics' was cre-
ated. It is targeted to be flexible enough for different types of sound coloration
including extreme and unusual settings, but does not feature a dedicated
limiter.
Selection between the standard or vintage dynamics section can be made per
input channel during configuration of the console.
Soft Clip In addition, a soft clip function can be activated in the D21m Mic/Line pre-
amplifier.
