It would be great to be able to sent the L/R feed to one or more of outputs 1-6. This could be tapped before the output processing for main L/R.
While the “Alt-outs” of the CQ-20 allow you to duplicate other outputs, you don’t have any processing control on those outputs.
Use case: using output 1-6 for additional main speakers, e.g., fills or subs, and then while still being able to use EQ on each output to give each speaker what it needs or set up crossovers.
