So i have had the Denon poa t2 poweramp for a while and decided to buy the emotiva pt-100 preamp i plugged it in no sound... from my pc its an aux to rca cord the rca goes into the pt100 analogue input (AUX) the analogue output has a rca to rca lead going from the pt100 into the denon poweramp the speakers are connected its on the correct source the volume isnt muted yet i have no sound at all help
