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 LMS-D26]

Outputs 2 (routed from L input) and 4 (routed from R input) [2 and 5 for LMS-D26]

Outputs 3 (routed from L input) and 6 (routed from R input) – LMS-D26 only]
