Technical Question

My preamp has three outputs on the back. Could someone please explain the difference to me? Does it make a difference which one I use? I'm using a Mesa Boogie 50/50 power amp, if that helps. Thanks in advance.

1) Balanced Line Out (-10dBV)
2) 3V RMS (+10dBV)
3) 1V RMS (0 dBV)

The balanced is just that. A balanced signal. You will not use that going to a guitar power amp. It's for going into boards with balanced inputs.
The 3v will give you a hotter output and overdrive the power amp more since you are putting more voltage to the input stage of the power amp.
That's the one I'd use.
The 1 V is the weakest signal, but if you don't want any power amp overdrive use it.
What kind of preamp is it anyway???

neat

Another neat thing to do is plug directly into the poweramp.. I never thought of this untill I talked to the guys at mesa and they said that's how they test them at the factory. it gives you tons of clean natural tube tone.

It's a Peavey Rock Master - a $100 special. I haven't been able to find a preamp that I'm happier with. My reasoning for asking the question is because I've been using the 3V output and it seems a little noisy, i.e. it's very sensitive to pick noise, scratching, etc. that I don't want to hear. It seems almost to accenuate those noises.

Yep. They told me the same thing when I had some trouble with the amp itself. I need the distortion, EQ, and channels from the preamp though.

yea

you ever think it's the power amp and not the preamp that's the problem. Try them at the store through a 290 and hear what the preamp should sound like.
