 I have an older Denon 3805. The auto calibration sets the distances correctly for all my speakers except the sub (but that's expected). It makes them sound a little better also by messing witht eh room EQ.
What I don't understand is that it sets all the speakers to +12dB. Why do that? Why not leave them all at 0dB gain. They are pretty sensitive speakers (Klipsch RB81's, RC62) too so it's not like they need lots of power to reach ear bleeding levels. |
Matrix,
Interesting finds on your Denon; running my Onkyo's auto setup made inaccurate distance settings for most of the speakers including the sub -- I cant comment on the sound because after eyeballing the values it fed in for calibration volume, I canceled the system and reset it manually to my liking once again....
And yes, that setting of "+12dB" seems really really odd for the auto setup, I agree; I dont know why your receiver is pegging EVERY CHANNEL to +12dB; on my Onkyo, 12dB is the highest you can set each channel, and I dont think its recommended to pin that value that high on any channel setting -- this is an interesting find, as when my installer first set everything up with me, and he did not have good luck with the auto setup, he went ahead and dialed the values in manually....he came up with +12dB for the center channel, which seemed ridiculous to me as that was the highest the channel could go, aside from the fact that the front soundstage especially from the center was too overpowering for my room. I since adjusted his settings and dropped that center channel to +9dB....
My automatic calibration system dropped all the channels of my system into what seemed to be too low a range; it came up with 0dB for a few of the channels, and even negative values for the surrounds -- I believe it only gave my sub a +1 dB value. This did not seem right to me -- while you say +12 seemed to irk you for all channels, I agree, but I dont think 0dB is correct either; I mean, wouldnt that suggest too weak an output from that channel?
How do these auto calibration systems come to their findings? I mean, why are the values completely different sometimes when you run the system a few times? How do we know what's correct?
