Recently I've purchased used Denon AVR-X1200W and hooked up 2 front floorstanding speakers, 2 rear bookshelf speakers and a brand new Yamaha NS-SW200 subwoofer to it.
I've calibrated the system using Audyssey, set the reciever on LFE+Main for the beginning, and noticed that the bass on Adyssey AUTO mode is distorted, even at low volume, producing some kind of a 'flobbing' sound on low frequencies like explosions at movies etc... When I play the same scene at the same, or much higher volume on 'DIRECT' mode, the bass is ok, flobbing sound is gone, but all the good sides of Audyssey's digital processing such as dynamic volume are also gone, ofcourse...
I've tried all kinds of settings like just LFE, all speakers set to small, crossover frequency at 80 hz, but nothing helped. The subwoofer produces distorted, flobbing-like sound when AUDYSSEY is turned on.
So, I'm wondering what's causing this... Is it the LFE output on the reciever? Could the sub pre-out be in malfunction? Or is it the subwoofer?
Thank you very much in advance...
I am having the same issue with my AVR-S910W.
All of a sudden the bass at certain frequency is distorted. Sounds terrible. I thought my sub was bad.
Also, the system keeps setting my sub to -12db after Audyssey setup. It didn't do that in the past. I have set the level at half, when I calibrate, like I always do. I even tried setting it lower.
(Denon wants me to buy another receiver)
Also, sometimes when I enter the online setup page, its says "AVR-X2200" not AVR-S910W
(it goes back and forth)
I've downloaded and reinstalled the firmware and re-calibrated many times, but nothing works.
I am on firmware Version 4400-6451-4035, DTS Version 3.90.50.00
Now today, I noticed that whenever I pull the power cord, the Audyssey calibration gets deleted. Is that normal?
I am going to do one more full initialization and re-calibration.
EDIT. One more, Zone 2 is not showing on the online setup web page.
