This particular unit is from a local church and supported audio and video from a sound booth to the nursery. Unit is 100% functional and can substantially improve video quality. All audio is stereo, so keep that in mind, although for home use, several matrixed surround modes are still an option, via a reciever. If video support is the primary use this is highly configurable to achieve a beautiful HD picture.
