Hi There I am trying to connect a crown xti 4002 to my Denon x6700 receiver and use the amp for my Polk ES60 floor standing left and right speakers. I see the preout on the Denon is 200 mv and the input sensitivity on Crown xti 4002 is 1.4v. I am connecting the preout from my Denon using rca to xlr cables. Would I need a solution to adjust the input sensitivity of the Crown xti 4002? I dont think the input sensitivity can be changed on the Crown amp. Would you be able to provide guidance or know someone that can?
