Stereo / Mono Formats
There is only one ‘standard’ layout of the processing blocks, but flexible routing and control
linking allows this layout to be adapted to a wide variety of applications.
There are two ‘Formats’, Mono or Stereo. With the Mono format, all outputs have unique
parameter settings, and all outputs are identical in terms of processing functions and routing
capability. This is the most flexible Format.
Stereo format pairs the inputs and outputs for stereo operation, the parameters of each member
of the pair being identical. The routing of inputs to outputs is fixed. This format is intended for
symmetrical stereo operation, eliminating the need to make identical parameter adjustments for
each channel.
The channel pairing is:
•
Left and Right Inputs
•
Outputs 1 (routed from L input) and 3 (routed from R input) [1 and 4 for DP2160]
•
Outputs 2 (routed from L input) and 4 (routed from R input) [2 and 5 for DP2160]
•
[Outputs 3 (routed from L input) and 6 (routed from R input) – DP2160 only]
