I have a Kern preamp and am about to order a QSC PLX2402. Question is, does anyone know what the output voltage of the Kern pre is? Right now I'm using the power section of a Carvin R600 and the Kern clips the Carvin with plenty of room to spare. I believe Carvin poweramps have an input sensitivity of 1V, but I don't know if it's the same if using the effects return of the R600. The 2402 has an input sensitivity of 1.5V, so I'm wondering if I need to get it modded to have a lower input sensitivity to be able to drive the QSC into clipping. I know there are talkbassers out there running a Kern/QSC setup, and just want to know how well the Kern powers their QSC.
