Gonk,

I have read your setup guide. I am using my 83 with a 970. Analog section is amazing, esp with vinyl. I love the HPF/LPF switch (also, the 2-ch out of the 83 is excellent, DVD-A never sounded so good) Yet I have NO idea if my LFE is calibrated properly for 7.1. I have referenced all speakers in the 83 at -7db with the sub at +3 db. This should account for the -10db of the LFE encoded channel and still avoid clipping.(all speakers are set to large) Yet, when I use the test tones in the AIX bluray I am about 10-12db too low in the sub channel while coax out is level across. Listening to films and switching back and forth between coax and 7.1 (using a DD or DTS signal) They sound about the same, but is the bass coming from the L/R or from the LFE? I have no way of knowing.

Is there a test tone disk specifically geared for the LFE channel?
