The compressor is great to have... But, even though it's a master comp, the USB audio player does not run through it. At least, I haven't had to push it on the WAV/MP3 side of the 970.
I do like using the 1/4" adapter to bypass the speakers. I did shut them off in function mode but when I went to teach a voice lesson after a gig... No sound. Function-Utility-config2-speakers headphone Sw-Exit... 5 button pushes later, got my speakers back. Pull out the adapter, one move and no buttons.
Also, if I'm at the gig and want to flip on the speakers, pull out the adapter works the best.
