Well after hearing the painful sound of power amp clipping into my precious, precious speakers behind me at a gig last friday, I've bought a power amp. Being poor I couldn't afford a really good brand, and avoiding Behringer because they are not friendly people, I bought a Phonic XP2000. It's the model up from the MAX series, has an extra fan and can handle 2 ohms/channel. Lots of protective circuitry too, protecting my babies (my cabs). Here it is: http://126.96.36.199/partner/modules/product_explor/products_detail.php?product_id=97# I think I'll run it stereo into my two 8 ohm cabs (400W/side) It's 600W/side into 4 ohms, 960W/side into 2 ohms or 1980W bridge mono in 4 ohms. I don't think I'll be short on power! My questions however are: 1) I'm using my Trace head as a preamp, with the Line Out plugs and patch leads. Will the gain knob on the Trace control the volume from these, or will the volume knob? Should I set the gain really low and the volume up, or will I hurt the power section of my Trace? 2) How the hell does the 4 pole speakon thing work? Surely there's 4 wires inside the cable....but the speaker will only make contact with two of these right? How does it get the whole amount of pwoer to the speakers? Thanks!
