Creating SR-Series Matrix Crosspoints

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 subtraction 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 canceled,

sound reinforcement, and ungated/recording version. As shown in

Studio, different versions of the input processing are represented 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.
