I finally got my DINAH running into a Kenwood TMV71A as an all star node and it sounds like crap. I set up the TMV71A menu 518 and 519 to the appropriate settings. I adjusted everything i could on the allstars RPi3 node. I noticed a jumper mentioned jp1 in the manual but i do not know what it is for. Does anyone out here know? Does anyone have any experience with bad audio?
