Hi Guys,
Thanks for the advice.
No. My Onkyo does not do automagic calibration
The only time I use reference volume is to calibrate my 5.1 set up.
I think I may have figured a way of setting a new reference volume level for the 7700.
I hooked one of my speakers back onto the Onkyo, set the Onkyo to the indicated reference volume setting, calibrated the speaker to 75 dB using DVE as my source and a Rad Shack SPL meter.
Then hooked the speaker back onto the 7700, and adjusted the pre/pro volume down until the SPL meter read 75dB.
Noting the new volume setting, I calibrated all other speakers in the system to 75dB.
I think I have everything calibrated correctly now.
