EQ before Preamp?

Bob I'm getting a bad vibe from you question. Are you planning on using an equalizer or are you already set up with one in a way that is different from what was suggested by Jaybo and myself? Are you an engineer? I can't figure why you are calling a preamp an attenuator? It's a preamp!!!! I don't think Joey asked any questions about an attenuator. See I don't like calling speakers transducers either. Keep in mind, we are trying to assist Joey and in my experience preamp receives signal from source, signal flows from preamp to equalizer where the various frequencies within that signal can be tailored to one's preferences. I know of no other way, if you know something that Jaybo and I don't, then feel free to teach us. I just don't understand why anyone would not want to hear the source signal through the preamp first and then determine what frequencies you want to boost or decrease. This setup works and that is why I recommended it to Joey.

Okay Bob, I guess I was weirding out last night, my apologies to you. I understand what you are saying and in a tape loop, I am still not sure that the siganl is first presented to the preamp. Anyway, what I am saying is that when the setup has the input signal going to the preamp first, the equalizer will then have the actual input signal that would be directed to the power amp then to the speakers in it's pure form, which is the way it would be if there were no equalizer.

I used to put my Behringer before my tube pre-amp, that way the ss DEQ didn't mess with the "magic" tube pre/ss amp sound.

If you run the Behringer's room correction, it's correcting what comes out of the speakers. It shouldn't matter where it is in the path.

The advantage of having the EQ after the preamp is that you can then correct all your sources. Putting it between one source and the preamp only corrects that source .If you only use one source then you have the option of doing either.
