ok...i have a setup that is seemingly fairly common on this forum. i have done some searches and gotten some good info which i have used. i am now somewhat at a loss and feel the need to post my specific issue. please bear with me. QSC rmx 2450 poweramp / ampeg svp pro preamp / eden 410 xlt (700w)...clean no effects. i am using a warwick thumb with bartolini pickups and running it in passive mode exclusively. the eden is new, having replaced my old combination of boogie 15 and epifani 12. qsc came back from the factory with a clean bill of health. i have used 3 other preamps thinking there may be something wrong the pre. i have run the qsc in parrallel and in bridged mono. i have changed speaker cables. what continues to happen throughout all of these different scenarios is clipping at moderated volumes. it gets somewhat loud but nowhere near what it seems like it should. does anyone have any advice that i might try that i haven't already? do i need more power? that seems unlikely. any advice and/or tips are generously appreciated. thank you very much. ben.
