I've had my 3300 for close to 2 months and while listening to a CD the other night I heard some "variations" in the sound that I'm not sure how to interpret.
I have listened to the CD on another system (no Audyssey or any other special audio processing) and I do not hear the same "variation."
My receiver settings are:
Audyssey - On (Reference)
Dynamic EQ - On
Reference Level Offset - 0
Dynamic Volume - Off
I had the volume set to -19.
The "variation" that I heard seemed to be instantaneous changes in volume. It would suddenly increase, then later would drop to the original volume. This occurred a few times over the course of listening to the entire CD.
I checked my settings at first thinking maybe I had Dynamic Volume on and I just happened to have the volume set such that the compression was kicking in and out. But, the Dynamic Volume was off.
The Reference Level Offset has been kind of a mystery to me. I read the descriptions of the various setting over and over. Since the manual recommended using the offsets for various styles of music, I selected 10 db. The audio "variation" that I had heard was gone. After thinking about it, I thought that perhaps what I interpreted as just a volume increase was really the Dynamic EQ boosting the bass (I was running in Stereo so no surrounds). So, I figured that maybe the Reference Level Offset level of 10 somehow helped to smooth out the effect of Dynamic EQ.
My question is whether my thinking is correct. Can leaving the Reference Level Offset at 0 while listening to music result in sudden changes in the amount of boost supplied by Dynamic EQ? If not, then is there some other explanation for why the audio "variation" went away after adjusting the Reference Level Offset?
