a value of 1 means enabled and 0 "disables all effects", well on my HS510 this is set to 1 and on my XBR960 its set to 0. When I change it to 1 it sounds a little bit worse to me, Perhaps Sony changed this with the XBR960? I believe 0 means On and 1 is Off in the XBR's case.
I think the XBR960 has slightly different speakers (a super-tweeter?) and maybe a different subwoofer than my huge 36XS955. But the charts show the same 21-parameter list for all of these sets.
ASYS is the switch that turns on all audio effects, such as equalizer and tone controls. 1 is ON.
TRCV, BACV, and MDCV (treble, bass, midrange) determine the qualitative *behavior* of the EQ controls -- whether they're manual adjustments or somehow dynamic (volume-dependent). What I determined was that when they were all set to 2, I had the equivalent of a three-band equalizer in the parameters STRE, SBAS, and MIDL (again, treble, bass, and midrange). I got very uncolored sound by setting those three thus:
(In group order) MIDL=6, SBAS=7, and STRE=9. SInce you have an XBR960, your tweeters might be more aggressive than mine, and maybe a lower STRE would work better.
I don't remember what I concluded about SVHI amd SVLO, but I have them both at the default 4.
LOFQ has something to do with deep bass. I raised it from 0 to 5. Lovely!
I have not determined exactly what MIDT, TRFQ, and PSEF do, and so I left them at default values of 0, 7, and 5.
AGCL determines how the (poor) auto-volume level feature works (SteadySound), and I found it ineffective at the default of 9. I have since changed it to 2, but the feature isn't very sophisticated, anyway.
I got get very effective "theater-bass" enhancement from the TruSurround feature, by leaving the five values of BBE~BB2L at their defaults of 1-5-4-5-4.
When TruSurround is on:
BBE seems to be a switch for treble, with 1 = ON. I leave it at 1.
BBEP affects upper-midrange-treble. Can make sound nasal or distant-sounding.
BBEL and BB2L are for (I think) bass and deep bass. (It's possible I have those descriptions reversed; but it's easy to tell when you're listening to a thumpy sound track.)
I have no idea what BB2P does yet.
I have left TRS1 and TRS2 at the defautls of 4 and 2.
So . . . this means that my current, very satisfactory settings are, in order:
1-2-2-2-4-4-6-5-7-0-9-7-5-2 -- 1-5-4-5-4 -- 4-2
The charts imply that the "BB" or bass-boost settings also affect the other audio modes (Off, SteadySound, etc.). I haven't experimented. I perceive that the sound is less warm with much less (or less exaggerated) deep bass when I shut off TruSurround, but I haven't yet tried to EQ "Off" to match TruSurround. Maybe that's a lost cause.
I have to say: As an exprienced audiophile, I am very impressed with the sound of this TV! Voice was honky out of the box, and there was some kind of annoying dynamic audio thing going on, until I set up TRCV, BACV, and MDCV at 2 and made EQ adjustments, as detailed above. Now I'm very pleased. (Some of the models may not have subwoofers, by the way.)
While I was working on the audio settings, it seemed to me that the 3 settings of TRCV~MDCV were "remembered" even after a power-cycle with no WRITE. But unplugging and replugging the set always "erased" the errant settings, returning them to normal.
