Question: What is sound dba level?
Document: Amazon's entry level cable is not adequate. I recommend this sound bar as it is of good quality and value.
I would recommend buying a subwoofer to take your experience to the next level. I gave it a 4 because the sound is good but not great.
If you remove the power supply, the soundbar loses all its settings - which input you were on, the volume level and the settings for the sound enhancements. You have to set them all up again.Ok - not a problem if you have a reasonable electrical supply which most of us do.
The TV's audio is greatly improved with the Soundbar in use...perhaps not quite at the level of top-of-the-line home theatre systems, but it is a great improvement over the sound that comes from the stock tv speakers.
For less than half the cost of an entry level surround sound system this product is a very good choice. Mute those tinny built-in speakers on your flat screen and crank up the VSB 200 and you will enrich your viewing pleasure rather dramatically.
Using the sound bar means that now your volume indicator is on the sound bar in the form of 7 led's with 3 brightness levels. This works but it's not the same as seeing the volume level on the TV and knowing that the volume is say 27 or 15. Again, not really the fault of Vizio.As for the sound bar itself, it does improve the sound over what the TV can do.
They're pretty straightforward:- Power on/off- Volume up, Volume down, Mute- Input. Press this to toggle through inputs #1, #2 and #3- "TruVolume" button. Press this, and it goes into "TruVolume" mode which compresses the sound. For example, have you ever been watching TV and find yourself turning it up loud to hear the dialogue, but then a commercial comes on and it's excruciatingly loud? This mode keeps everything on the same level.
It worked great right out of the box, although I have yet to figure out how the TruVolume feature works. It's supposed to level out the volume so commercials don't come on louder, however I can't see the difference yet.If your in the market for a sound bar, you might want to consider all these issues. It might be worth a trip to the local audio/video store to see how they connect and how they function.
The sound bar arrived just today so this is an early review. Very easy to set up I,ve had no problems with the remote sensitivity or angle of operation, but the sound bar is only about ten feet away and at just about eye level. The True Sound does level the sound variation somewhat, although it's not perfect.The sound quality is quite good; much improved over the TV's sound output. (Panasonic 32inch LED.)
I am very disappointed with the Vizio VSB200 sound bar. The sound level slowly fades then comes back louder than it was set for. To use the remote you must be within 4 feet of the sound bar, it is easier  to get out of your chair and set it up manually. There is no indicator for the volume that you set. It is so large that it covers the TV IR ports and you must hold he remote high in the air to use it.
Answer: This is a measure of digital sound levels that charts are available for, different dba numbers will indicate what dba sounds levels are acceptable in different  areas.The living room. the bedroom etc.
