I've actually been having much frustration trying to keep the master ProChannel from overheating. Does anyone else here feel like these ProChannels are too sensitive? Of course I have no idea what I'm talking about...
...But it just seems like when using ProChannels, everything I'm doing has to be turned way down. The synth's output is cut dramatically (Z3TA I'm having to cut down to 25% or so). Outputs on FX chain effects and PC modules have to be turned way down as well. Sometimes I'll find that a not particularly loud synth will be overheating the master ProChannel, even when everything's turned down. So I turn it down some more, until it's barely audible. Then I figure I'll turn everything else down as well.
By the end of it, when I've turned everything down to prevent the master ProChannel overheating, and all the track's ProChannels are nowhere near overheating, the overall output of the master bus seems to be a lot lower than it would have been if I wasn't using the master ProChannel at all. Even with the master slider at 0dB, peak levels seem too low.
And the annoying thing is, the overheating of the ProChannel (for me anyway) is invariably caused by one pesky note of a synth part (which doesn't even seem louder than the rest). I see that red light come on very briefly, and it doesn't even seem to coincide with any loud event.
I wish I knew more about this ProChannel and gain staging business. I seem to be spending way too much time worrying about that red light during the mixing stage.
