Hey all. New to this forum, I have searched previous threads, found some instances that were close to mine but not exact, sorry if this may repeat. I have a AB precedent 600a, 1\/4 inch jacks for the feed. I have a JVC 5456x receiver. Has preout\/main in and scope out. I used scope out which allowed me to use the pre amp controls on the jvc. However, my amp attenuators would need to be full blast. My jvc volume control would then turn to the 12\/1 o’clock position for the loudest setting. The same as if using the jvc onboard amps. What am I missing here? Seems I am only using half the amps power. Amp nice and Luke warm. Limiter lights are working &clip lights up past the 1oclock position.
