It seems that the system uses only one mic for auto calibration. Then how does it sense (or measure) the direction of the sound during the process?

Is the system able to keep and switch to more than one setting based on different room conditions (e.g. when window curtain is used or not)?

Looking forward to your further review



Hi Valley,

Thanks, appreciate it. Good point on the HDMI OSD issue and I am sure that was their answer for your scenario. I guess they could have treated it as a seperate input, leaving the current HDMI source and JUST outputing the OSD, therefore not tampering with another signal, but this is just me being WAY too nitpicky ) and now that I am used to the soundbar display, there really is no need to have the OSD on my panel. Roger is correct.....the one mic sits (or should) basically close to your listening position and starts beaming off the walls and adjusts accordingly, you can run "beam optimization" or "sound level optimization" or both at same time. Yes, good question, the unit will save 3 different calibtation settings in Memory that you can call up at any time. (I guess you can actually have 4 at one time, 3 in the memory, and the default current, but, once you call up one from the three memory slots, the current is wiped out I suppose. (have not tried this.)

I actually ran the calibration again in a different more appropriate area for the Mic and (it is so easy to run) and saw improvement. I plan on doing some manual settings experimentation and reporting back, but so far I am loving this bar.

Is it true that the beam angle the system sweeps only describes how the sound goes out the soundbar rather than how (i.e. at what angle) it reaches the mic? I thought the ideal way for calibration is to maximize the sound coming from certain direction for the corresponding "speaker". For example, when the system calibrates the beam for the right rear channel "speaker", it should look for the sound reflected from somewhere behind the mic and try to maximize it. A single omni-directional mic obviously can not do the job.

I've owned the YSP2200 since December and I fully support everything Danbyx said in his review. I too do not have the ideal room layout, but the immersive sound field is still very impressive. When watching a Bluray or even a HD cable station I can definitely hear distinctive sounds to the left and right of me. It doesn't really produce true rear effects very well, but with the great depth and range of the sound field I don't really miss the occasional rear sound effect.

Also, one criteria in selecting a soundbar should be physical appearance (especially if you have a 'tasteful' wife!). In my opinion the aesthetics of the 2200 are truly top notch and blow away the competition. I went to ABT and compared the YSP with about 12 other soundbars and none of them came close to comparing with the sleek, unobtrusive nature of the 2200 or the great physical build quality. In fact, the 2200 blends in so well with my setup (sitting directly in front of a 40" Samsung A650) that most of my friends and family don't even notice it is there and consistently ask how my TV speakers sound so great .

The system knows it is trying to create several defined zones. L/R/Ls/Rs. It wants near/side reflections for the L/R and far/rear reflections for the surrounds. It searches within those general zones for the best returns.

Yes, that is correct.

It can, as long as the system is confining its search within a defined region. It does not "light up" the whole room at the same time and try to detect which directions are strongest. It sends out a narrow signal and checks how well it comes back. It does that many times before deciding.

It seems that the auto calibration algorithm has to make some assumption about the room in order to "guess" the desired reflection during the calibration. A common issue about this type of beam-steering based soundbar is its lack of the rear sound. It may be possible that using multiple directional mics or manually adjusting the orientation of single directional mic during the calibration can remove the guess work from the process and generate more accurate rear "speaker"
