I have the Avia disk and it has some awesome reference tones. My problem is that my Marantz SR-19EX only allows volume adjustments when its voicing its own internal reference tones. That means I can't adjust the volume of the 5.1 channels in real time while the Avia tones are sounding. Rather, I have to adjust the volume to the Marantz tones. What gives? Am I doing something wrong or is that the deal for all recievers?

IŽd say, adjust with internal tones, then verify with Avia and manually adjust if any are wrong...

That would be adjust it using the receiver tones then if you like go back with the DVD and measure. Virtually all receivers will have some kind of "on the fly" level management available via remote. If you make any changes go back in to the set up menu and adjust accordingly so you can keep the settings. Like other posters I have not really found a difference in settings between the receiver and external tones once I got beyond the budget receiver range.
The tones in the Marantz are meant to be a point of reference to obtain equal sound output from each speaker. If you are trying to adjust different levels for different frequencies this is not what the Marantz tones are for. That would be equalization, a totally different subject...If you want to tweek each volume while using a different tone source because your prefer their tones over the Marantz supplied tones, then do it with the remote in real time. This setting will not be saved to memory. If you want to keep it, write down the setting, and go back into the software setup and make the change so it is saved.
The SR19EX has a wide range of adjustment so you should be good to go unless you listen to a tone your speakers have a bad time reproducing, i.e. very low or high tones...
Good luck.
[quote]If you want to tweek each volume while using a different tone source because your prefer their tones over the Marantz supplied tones [/quote]I think you be be missing the point, it's not just different test tones. AVIA and VE are shaped pink noise specifically designed for 5.1 Dolby Digital calibration and recorded at -20dB and -30dB below a 105dB reference level.
Normally I find that either AVIA or VE used for calibration is a more accurate rendition of the source to speaker signal path anyway.
Internal test tones of receivers have certainly been measured to be inacurrate. Some by as much as 3dB off channel to channel. I would certainly trust the actual signal path i.e. what is coming from the DVD player thru the receiver's amps thru the speakers to the SPL meter more than just internal test tones.
The question about how to do it with the Marantz? I'd try a support call or email to Marantz to see what their response is.
I own the B&K Ref 30 and use its internal test tones. I have compared this to the Avia and Video Essentials and found them to be spot on. When I set the speakers to 75 dB for all speakers and sub to 72-73dB and then check it using the Video essentials disk with volume set to refference, all speakers read 75dB. Seemed accurate to me.KM
I'm glad yours is correctly implemented. Not everyone will be able share your good fortune.
