SR-Series Output Processing

The audio matrix is used to create different mixes of input signals and submix
signals to be sent to output signals and submix signals. Matrix crosspoints gain
values are shown in dB where 0 dB means that the signal level is unchanged.
Matrix crosspoint gains can be adjusted in 0.1 dB steps between -100 and +20
dB and may also be completely muted. In addition, the matrix crosspoint can
also be negated/inverted so that the crosspoint arithmetic creates a subtrac-
tion instead of an addition.
Matrix crosspoints associated with stereo virtual channels have a balance or
pan to control mapping mono to stereo virtual channels, stereo to mono virtual
channels, and stereo to stereo virtual channels.
The different versions of the input processing are selected at the matrix
crosspoint. The user interface provides an option for selecting the different
versions of the input processing including the noise cancelled, sound rein-
forcement, and ungated/recording version. As will be shown in Chapter 4
Creating Designs, different versions of the input processing will be repre-
sented with different background colors at the matrix crosspoint. The
SoundStructure Studio software allows the user to select which version of the
input signal processing at the matrix crosspoint.
The next figure shows how to interpret the matrix crosspoint view.
Outputs
The output processing for the SR-series of products is identical to the process-
ing for the output processing in the C-series and shown in the table and
following figure.
SR-Series Output Processing
1st or 2nd order high shelf and low shelf filters
10-bands of parametric or 31-band graphic equalizer
Dynamics processing: gate, expander, compressor, limiter, peak limiter
Signal fader gain: +20 to -100 dB
Signal delay: up to 1000 msec
