DSP Configurations

The PCM92 processor can be divided in up to four virtual machines, each of which can run its own algorithm. This lets you route signals from each input through a variety of algorithm combinations.

The PCM92 can use up to two physical inputs and two physical outputs at a time; configurations for the physical inputs and outputs are described below.

Single Mono In Stereo Out

A mono signal is split into a stereo signal.

Single Stereo

The left and right inputs are sent through a single virtual machine.

Dual Mono

The left signal travels through one virtual machine, and the right signal travels through a separate second virtual machine.

Cascade Stereo

The left and right signals are processed together in one virtual machine, and the resulting signal is sent to a second virtual machine, where they are again processed together.

Cascade Mono

The left signal is sent through two virtual machines in sequence, while the right signal is sent through two additional virtual machines in sequence. The left and right signals are processed independent from each other.

Cascade Mono to Stereo

The left and right signals are processed independently in two separate virtual machines, and their resulting signals are pro- cessed together in a third virtual machine. The final result is output as stereo.

Combined STereo Mono In

This configuration features two stereo machines. Each receives one of the input channels. The two stereo outputs are combined and output as a single stereo pair.
