Secondary Mix Matrix

The DSP architecture contains a secondary mix matrix that connects the mic/line inputs and virtual bus return signals to the virtual bus sends. The DSP Configurator user interface provides control of the secondary mix matrix, used to set levels from the post-processing input line and virtual bus return signals to the virtual bus sends. Each of the six mic/line and four virtual return inputs connect to a mix-point for virtual bus A through D. Each mix-point is muted and set to 0.0 dB (unity gain) by default. In general, mix levels are set relative to each other, achieving a desired blend of input signals at an optimal level close to, but not exceeding 0 dBFS at the output volume level meter.

The secondary mix matrix contains a section (see figure 44) allowing virtual bus returns to be routed back to the secondary matrix to allow further processing using an additional virtual bus processing block. To prevent feedback loops, a virtual channel is prevented from being routed back to itself by eliminating the mix-point that would allow that to occur.

In situations requiring extra processing, the virtual bus return output is routed back to the secondary mix matrix, virtual bus send, which then routes the signal back to a processing signal chain other than the one it was routed from.
