Whew, DB25s hooked up and ready to run to mixer and insert/parallel processing rack, master bus compressor hardwires to inputs 9 and 10, might try it as an insert but I think the discrete output and transormers will be best last in the chain rather than as an interstage thing before the final mixbus output. I imagine the IC opamp summing will muddy up the impact of that output stage, although I am losing my master faders this way, but I tend to keep them gunned up relatively high and run my sub mixes and some of my channels lower like a sane, gain staging conscious adult. Listening tests this weekend. Anyone have thoughts on having master faders post compression versus having the transformers be the last thing before the recorder and fine tuning my analog level at the compressor??? Hybrid mix scheme here. Anything goes I guess?
