Primary Mix Matrix

The DSP architecture contains a primary mix matrix that connects the mic/line inputs and virtual bus returns to the line outputs. The DSP Configurator user interface provides control of the primary mix matrix, used to set mix levels from the post processing inputs and post processing virtual returns to each line output bus. Each mic/line input and virtual bus return is connected to a mix‑point for each of the four line outputs. In general, mix levels are set relative to each other, achieving a desired blend of input signals at an optimal output level, close to, but not exceeding 0 dBFS at the line output volume block level meter (while accounting for processing that can occur in the line output signal chain).

Shown below is a block diagram of the DMP 64 represented in the DSP Configurator, with a red box indicating the primary mix matrix.

NOTE: Although the virtual bus send and return lines, A to D, are shown as end points in the block diagram below, they are connected A to A, B to B, C to C and D to D.

From the primary mix matrix, any or all of the six inputs can be routed to any or all of the four outputs. Any or all of the six inputs can also be routed to the secondary mix matrix.
