Right now I have no problem running the balanced output of the MP20 through a TRS cable into my mixer insert. If I plug in halfway or all the way, it makes no difference.

It does make a difference actually.
The phase of the signal will change.
You'll be flipping the signal 180 degrees when you have it halfway out.

Avoid the loop....you'll go looopy :D
Pre to RNC to Desk.

TRS should be fine.....halfway out for proper phase.Remember it's '+' on the tip and the desk insert input is actually sleeve...that's why.

I'm sure you're right; since I got the MP20 (recently), I've only recorded two sources at once, both through the MP20. Hence, I never noticed the phase difference. I will correct that.

However, I thought the benefit to running the RNC in the pre's loop was so that I could make adjustments on the pre without having to reset the threshold on the comp. However, the MP20 doesn't have input and output controls, just a single gain control.

So what's the point of a balanced insert loop on the MP20. Why include it and not run everything in line after the pre?

BTW, I'm thinking of swapping the RNC for something with balanced I/O, as I don't want to deal with -10/+4 issues (I'm not too concerned about noise issues). I've heard others have had problems. What do you think about switching for the presonus ACP-22 compressor? It can go dual mono, and has gate functionality and balanced I/O w/switchable -10/+4. Or maybe even a DBX 166xl? Are these inferior sonically to the RNC?

I plan on using it only for tracking instruments, not any program material. Mostly voice, acoustic guitar.

Thanks for the input,

TYY, the RNC operates at +4 dBu, so you won't have any "-10/+4 issues". Also, I wouldn't part with the RNC unless you want to spend a LOT of money.
