DSP Configurations

The PCM96 Surround processor can be divided in up to four virtual machines, each of which can run its own algorithm. This lets you route sig- nals from each input through a variety of algorithm combinations.

The PCM96 Surround can use up to six physical inputs and six physical outputs at a time; configurations for the physical inputs and outputs are described below. The software plug-in also lets the PCM96 Surround use up to six inputs and outputs via FireWireTM; those configurations are accessible in the software plug-in, and are described on page 18.

When using the PCM96 Surround in one of its surround modes, it is critical to know how audio is routed to the algorithm. This applies both to the way IO connects with the outside world and the way the signals are distributed within the algorithm.

Preset availability within the various surround con- figurations

In almost all cases, a surround preset is usable in any surround configuration, whether four or five-channel, 2-in or multi-in. Parameters which are not available in a given configuration (for example center levels in a four-channel config) are hidden. Factory presets have been written in such a way as to work satisfactorily in all configurations. When creating user presets, it’s rec- ommended that the preset be auditioned in all configurations.

Signal distribution inside the algorithm

There are two versions of the 4-channel machine: 2-in/4-out and 4-in/4-out.

By the same token, there are two versions of the 5-channel machine: 2-in/5- out and 5-in/5-out.
