I received the AIX Blu-Ray "Audio Calibration Disc" from Oppo today. What I discovered was that in playing any of their subwoofer tests in 96KHZ format (DTS MA, Dolby True HD and LPCM ) there was no sound at all (16KHZ to 160HZ ) from the sub unless I disabled Audyssey using the control on the NAD T785 receiver. I double checked by using a meter. 48khz sources are fine. I checked the Oppo setup and the NAD. Note that my Audyessy setup is in Audyessy Pro as done by my dealer.
Crossover is at 60HZ, I tried raising to 120HZ to no avail.
Anybody run into this ?
