Ok, need help..losing my mind..

Hello goners, I have a dedicated 2 channel with a TB of music, I'm trying to be able to play those files thru my in wall speakers I have throughout the house, those speakers are connected to my Denon avr 988 home theater receiver on the second zone. My preamp on the 2 channel is a maple tree 2ase. I've tried input to output and reverse from the Denon to the maple tree but no luck. I actually had it hooked up before when I had another preamp but have forgotten how I did it, old age. Thanks in advance for any help.
