For an output with a studio pre, I found the effect send to have the best tone. It had a less compressed feel than the standard or recording compensated outputs.
Whoa, that sounds...odd? I mean, I can definitely see the compensated outputs being weird-sounding but would have figured the regular ones would be fine.
That rig looks awesome! Which control(s) do you use to turn your volume up and down? My instinct from running rack PA systems would be to set the pre output volumes and power amp volumes and leave them alone, then use the master to control my level. But it seems like the manual recommends parking the master at 5 and then adjusting something further down the chain...?
