Questions & Answers for Vizio VIZIO S4251W-B4 5.1 Channel Home Theater Sound Bar with Subwoofer and Bluetooth

Question

wifi interference

Im really interested in the Vizio S4251W-B4.

I believe the rear speakers are wired to the subwoofer and the subwoofer communicates wirelessly with the soundbar (which is perfectly fine with me).

Does anyone have any additional information on whether the wireless communication between soundbar and subwoofer will introduce any wifi interference? Does anyone know if the wireless communication is indeed on the 2.4 GHz spectrum?

Im concerned that the wireless communication between the soundbar and subwoofer will interfere with my router's wifi connection which I will use to stream to TV and Bluray player.

The sub-woofer is a bluetooth device, so it will not interfere with the 2.4 GHz spectrum.

Thank you for inquiring about our product.

The soundbar uses a pairing function to link to only the Subwoofer, preventing wireless interference.

No, but... They do connect to the wireless subwoofer. This allows you to place the the subwoofer by your couch plug the satellite speakers into it then just put them on the end tables on either side of your couch and your ready to go. No wires across the room! Plus they sound great.

Yes, The remote that comes with the sound bar has a small LCD display. There is a button on the remote called menu, press it once, then use the arrow up button to scroll through the different functions on the LCD screen. As you scroll through you'll get to one called VZtvRmtOff... Now press the right arrow button once, it's now on then press the menu button once more and your done. It's cool, I have an LG TV and it works with mine. They must have similar codes.

My soundbar works with all the remote I have that controls the TV volume out of the box. On the remote menu, it has a VizioRemote setting that is defaulted to "ON".

I have an LG TV and when I have the VizioRemote setting to "ON" position, my tv remote controls the soundbar. Since you have a Vizio TV you should not have a problem with this.

Question

How will I know when it is processing 5.1 or stereo signal

Is there any visual indication when the device is processing and receiving a true 5.1 dolby signal or do I just have to rely on my hearing?

Actually the Visio support answer is not correct. I was the one who asked this question. After playing with the unit some more and streaming movie from Netflix with 5.1 audio and setting up my DVD to output from PCM stereo to DTS Re-encode, I noticed that a "[ ] Dolby" sign lights up for about 2 or 3 second before the sound comes out of the speaker.

The Dolby sign will not come out if you are sending 2 channel signal to the unit. So, make sure that you see that light else, you will want to look at your other device setting making sure that it is sending a 5.1 signal to the soundbar for you to get a true surround.

Thank you for inquiring about our product.

There is not a visual indicator that shows when 5.1 audio is being produced. The device will output what it receives. If it receives 5.1 from your connected device, it will output 5.1.

The system does not have a wattage rating. What it does have is a sound pressure level rating of 102 db. With a frequency response of, 50 Hz - 20 KHz. The wide frequency range allows all the highs and lows to come through nice and clear, even at the highest volumes. The system has 11 individual speakers that range from two 3/4" tweeters to a 6 1/2" High Excursion powered sub-woofer. I have this sound system and I love it. In other words, not only is it loud... When it's loud it still sounds great.
