Question: What inputs does this system have?  I have a flat screen with HDMI connection, how do I get that sound through this system?
Document: I have been wanting a surround sound system every since I got my 46" flat screen last year. I can not believe how realistic stuff sounds. Now I am on a mission to get all action packed movie!
This is a very nice system at a budget price. It is not for the audiophile, but for home theater on a budget it is tough to beat. It is very easy to install and integrates seamlessly with our flat screen HD TV with an HDMI cable. In set up mode, it will automatically balance your surround sound speakers with the included microphone. (Awesome!) It will blow you out with 1000 watts of total power.Be warned -The only caveat is the speaker wires are way too short.
This is because my DVR is technically always on.Normally all you would have to do is connect all your inputs to your television and then use a Optical Cable to your sound system. Most if not all newer and higher end TVs support this as my Dad's Sony 40' TV does this well.One thing to note is this system works great out of the box if your have the proper cables. Get an HDMI Cable and Optical Toslink Cable as well.
Decent, obviously entry level. Sound can get loud and full which is nice. Did the auto-calibration and the speech was still too quiet so I turned the center speaker up quite a bit.One irritating negative is that it is in no way a receiver (which it isn't advertised as). It has no inputs for HDMI for other devices.
its a good loud system, i love all its little features that connect to my flat screen. i would recommend it well worth it.
Hooked up to DirecTV STB with optical audio cable so the stereo is getting Dolby Digital sound. Vocals are strong and crisp. Treble could be a little better. Midrange is ok. Bass is good but I have the sub turned up 1 notch below max. There are no HDMI inputs so you have to hook up your other video sources directly to the TV. It has 2 digital audio inputs (1 optical, 1 coaxial) so make sure that will be enough for your needs. Overall, good budget system.
This was to replace an older Yamaha Dolby system, with this I get a DVD, FM Radio, and other inputs to my Television set. The bass booms when it is told, and is gentle when not needed. Best priced system for such  a big sound!
Purchased this system for our family room which is a little on the smaller side. The sound is rich and full, the subwoofer is better than expected, and overall we're very pleased. Good TV sound and excellent DVD and iPod sound. Moderately priced as well, which is a bonus. *NOTE: Fiber Optic audio and HDMI video cables are NOT included and must be purchased separately. * The system does include a cable for basic video connection.
That being said, definitley purchase this system. Do note this is not a Blue-Ray player, seriously I thought Blue-Ray would be standard by now and I didn't even question it during purchase --- I read it plays DVDs, my DVDs are all Blue-Ray so didn't cross my mind at all.Inputs...there is one HDMI input and one Digital Audio input. I run these out from the TV to the receiver as my other componenets are connected directly to the TV.
So if you plan to do the same just get the one with [HDMI IN] for external device.Overall I rate this system 3 stars because it plays nice sound, however the menu on remote is nightmare, also the LCD display is small and hard to read from a distance.
Answer: Optic cable, I have hdmi and optic for sound and works great.
