Question: Would this be compatible with  VIZIO S4251w-B4 5.1 Soundbar with Wireless Subwoofer and Satellite Speakers?
Document: Had our Satellite tech come over and he helped determine problem was actually with my A/V Receiver. Replaced the A/V with new Denon and Soundcast is working fine again.If you buy just realize that not all programing on cable or satellite is broadcast in 5.1 Surrounf Sound so can not broadcast something it is not receiving.
I chose this system for my bedroom surround system. Running leads to the rear speakers through the attic would have been impossible. I did not want to have the speaker wires showing. The Soundcast SCS100 was the wireless system I chose.Set-up was very easy. Best of all, the system transmits the sound very well. I cannot tell a difference in quality from when the rear speakers were wired from the receiver. The system consists of a Yamaha RX-V371 receiver and KEF KHT1005.SE 5.1 speakers.
No interference from other wireless devices. You should understand that not ALL programming is broadcast with 5.1 surround sound. So don't think there is something wrong with the product because you do not always hear sound from the rear channels. I would recommend the product as it does what was described.January 2013 Update:Over the past few months I had what I thought were either transmissions or receiving issues with the Soundcast units. It did not seem that they were working properly (blue lights were our). Called Soundcast tech support and they were VERY helpful even months after purchase!
The reviews I read about this product were just a bit mixed but way more favorable than the cheaper alternative sold through Best Buy. I bought these in conjunction with the Denon 5.1 Surround Sound System also reviewed by me. Frankly the funtionality is just as described ... the rear speakers sound great without the need to run wires. The transmitter and receiver are set up with "line of sight" about 25 feet apart. There is no interference of any kind. (there are 2 PS3s running wireless connections about 5 feet away).
I had never heard of the Soundcast company, so I was rather apprehensive about ordering. However, based on so many other positive reviews, and such a low price, I took a chance. This product is very easy to hookup and works like a charm. I had considered another alternative (likeJBL WEM-1 50-Watt Wireless Amplifier and Expansion Module (Black)) which is considerably more expensive. I needed a wireless alternative for my surround speakers in a 5.1 surround setup, as running wires through the wall or under the carpet were not feasible in an apartment.
It does work well though if you are not trying to have a 5.1 setup where the sub and rear surrounds are both wireless.
I have to 2.4GHz wireless N routers within feet of both the transmitter and receiver and I still get a clear signal. If you not comfortable running cable through your ceiling and don't want to see wires this is a great item. I've had it a few months now, and I don't think I'd be able to get a 5.1 system with my wife's blessing without this. I will probably end up running the cable through the ceiling, but for now this works GREAT!
i have a onkyo receiver, enjoy a lot 5.1 audio but hate the posterior speakers cables liying on the flor or on the wall. the soundcast connects to the rear speakers connectors on the receiver and transmit the signal to the receiver part. works well
Purchased based on all of the reviews I've read.I have a fairly nice, mid-higher end 5.1 system that I've put together. Due to room dynamics, running wires was next to impossible (rear speakers on exterior wall which is a huge hassle). After stressing out about it and not using our rear speakers for some months, decided that the cost of this compared to our system made it worth it to try out and solve our rear speaker problems.I am _very_ happy with this product.
This is really helpful with saving energy, since not everything that comes through my receiver is actually capable of being sent to the rear speakers in my 5.1 surround sound setup. So, when some kind of content does engage the rear speakers, they simply turn on. I don't have to do anything!3) Excellent sound! I can most definitely hear both an increase in both audio fidelity and volume. I'm very impressed. I actually had to turn the soundcasts down to the lowest volume setting because they were competing with my front speakers!I'm more than happy with this purchase and really glad I made the switch.
Answer: As long as you have outputs for the rear speakers, you can plug them into the soundcast and use them.
