Question: I need to connect this sound bar to an older model big screen ULTRAVISION TV. It has the plugs in the rear, no HDMI connections.
Document: Firstly, the TV must recognizes the external speakers. In case of mine, i need to manually key in model number so that the connectivity can be established from TV. Secondly, the sound bar need to be configured so that it will recognize the input coming from optical cable rather than from other means.The overall quality of this sound bar is acceptable, good for watching sports.
First problem was that there no listing for the model I purchased from Amazon (above) on the Vizio web site! Tech support was not too helpful and wanted to spend as little time with me as possible, kept referring back to Sony the maker of the TV. As of right now the sound bar is sitting in the shipping box.
Very good surround sound. The only problem I had, which may be a big problem for some is the option to connect a subwoofer. When I connected a small subwoofer that I had to the subwoofer jack it did not work at all. No matter what I do I cannot get sound out of it. This is why I gave this sound bar only 3 stars. But considering how good the bar sounds by itself and the low price of around $80 it cost me, I kept it anyway.
I love my 40&#34; Vizio sound bar! It's sleek and goes very well with my 60&#34; Vizio TV. The quality of the sound is fantastic! I'm a big sports fan and love having it for that purpose. I would highly recommend this sound bar for anyone looking to improve their home entertainment experience.
I personally like the design as well. It rates five stars for the price and the aforementioned sound qualities. My unsolicited advice is that if you need more, spend more as I did for the sound bar in my TV room. Thanks to the fellow Amazon shoppers who answered my installation questions, I purchased the recommended RCA cable and I was set to go upon delivery. By the way, I am fortunate in that my satellite remote controls the sound bar volume as well.
Given the price of this, I would consider this a good buy. I just moved out of my big 3 bedroom 2.5 bedroom house with a very open floor plan to a 2 bedroom apartment. With this move I decided that I didn't need my Yamaha AV receiver and 5 speaker hook up anymore. I don't really want to be "that guy" in the apartment building because when I'm watching sports and action movies I like to blast the sound. I mean if you have it, why now?
Vizio sound bar was selected because a Vizio wide screen TV had recently been purchased. Selecting a refurbrished sound bar saved about 50% compared to new. We are pleased with the result.
I have originally looked at 38&#34; model, read reviews liked it, then I saw a selector on Amazon page, where you could select 40&#34;, so I did, the bigger the better, right? - Wrong. The 40&#34; model is not what you want, sound quality is very low - watched hockey game with this thing connected to my Samsung TV, the volume was &#34;floating&#34; from low to high.
As you know the sound on most televisions these days is not all that impressive. Most mfr figure you are going to hook it up to a 600 watt surround sound system. While I do have a surround system on the main TV I have one in the bedroom that I do not need the &#34;home theater experience &#34;for.
This was received in the time quoted. Easy to install and adds a great sound to my new 50 inch vizio TV. Out of the box I heard a big improvement over the TV speakers.
Answer: Yes you can connect by way of plugs in the rear of sound bar
