Sub Test Tone: Avia II vs Denon

[Alex2507]

Just looking for confimation that I should calibrate my sub using a test tone from the Avia disc as opposed to the one generated by a Denon 1920 DVD Player.

Thanks,
Alex

I can neither confirm nor deny that.

Do you already have the Avia disc? Have you already tried out both and could tell a difference? If not, please try both and see if there's any difference. That way, you can help us to know. Thanks.

I have the disc and have tried both. IIRC there was a difference. I'm inclined to not trust the tone generated by the 1920. I just yanked a 2 channel amp out of my system and now it's time to recalibrate ... again.

I'm going to see where the level of the sub is with the rec'r gain maxed out through the 6 channel input as that produces the lowest sub volume. From there I'll level match everything everything else. That way if I should switch inputs in mid play back the levels will be matched to the same reference.

I like the tones used in the Avia II disk. I prefer them over my receiver's tones which run quite loud (85 dB). The Avia disk will let you run low, medium or high volume calibration too.

The Avia disk will let you run low, medium or high volume calibration too.

I just want to add that the variable reference volume is controlled by the master volume setting of the rec'r. Using the Avia disc I started with -15 MV and +10 sub gain which produced 74dB out of my 2 subs from the Avia disc with my rec'r source set to 6 channel.

The Denon test tone made it easy for me to level match the 2 subs because it plays a sub test tone continuously without switching to other channels like the Avia disc does.
