With more performers using IEM, a few more aux mixes would be welcome. Ideally, there would be two stereo groups (as on QU) that could be assigned to the headphone outputs. Wouldn’t need the full complement of output processing. PEQ and limiter would be nice. GEQ and FBA aren’t necessary. If processing capacity is an issue, this would still be a useful feature even if there was no output EQ or limiting.
