Vista 1 Digital Mixing System
For all possible channel types - mono, stereo, 5.1 - the metering goes with it,
as shown above. Priority was to have as large a bar graph meter as possible.
The lower area is configurable for displaying different options, depending
on the channel type, such as a surround image view, or a history diagram of
incoming or outgoing signal waveforms, for spotting anomalies in the audio
signal, such as overloads or signal loss.
Another option in the lower portion of the TFTs is a bus assignment view,
giving an overview of the channel's current bus assignment, e.g. on a single
channel where bus assignment is changed frequently.
The control bay metering differs in that it is mainly made to show output
channels. More views are available, e.g. all AUX outputs, all groups, all
programme masters, direct outputs, bus outputs, N–1s, matrix channels, etc.
Four user pages can be configured. One has ten slots in one row, one 20 slots
in two rows, and two have 40 half-width slots in two rows. The two slots at
the right of the control bay TFT screen continuously show PFL and CR levels.
The illustration on the previous page is an example of a meter screen with
mono, stereo and surround channels and different views in the lower area –
such as metering of the L2 channel, history, bus assignment and surround
view. Further information is displayed as well, such as gain reduction or
surround signal type.
Level Meters
The level meter bargraphs indicate digital peak values including headroom
of mono, stereo, 5.1 and N–1 channels. The meter scale always is in dB
FS
with 0 dB at the top, with an additional overload segment clearly indicating
FS
overloads. Stereo meters feature a correlation meter on top of the meter bars,
both on stereo inputs as well as on stereo master channels.
Above the level bargraph area gain reduction meters are added. Clipping is
