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.
