Summing Matrix Tab
The Summing Matrix (Figure 21) allows the user to route inputs to outputs within the processor. A maximum of 232 out of
512 connections between input channels and output channels (cross-points) can be made in the Summing Matrix tab. Each
input channel can be level adjusted independently to individual output channels.
The Show Matrix Rows drop-down is used to select which inputs are displayed for routing. Inputs are the eight channels of
processed inputs. Matrix In 9-16, 17-24, and 25-32 are only used for unprocessed AVB inputs.
Matrix Modes: Summing or Direct Routing
The Summing Matrix has two modes: Summing or Direct Routing. The mode is controllable via a select button at the top left
of the Summing Matrix display window.
Summing is the default setting that allows the user to route multiple inputs to single or multiple outputs.
When the Direct Routing button is selected, only one of the input channels may be assigned to one output.
Summing Matrix Operation
In both modes, the gain value for any matrix cross-point can be adjusted. The gain range is -90 dB to +20 dB, where -90 dB
equals -infinity dB.
To select which group of 8 inputs to view at any one time, use the Show Matrix Rows drop-down menu above the matrix
display in the middle of the screen.
The lower right hand corner has a display indicating the number of cross-points in use. Of the 512 possible cross-points,
232 can be set simultaneously.
