This active 5.1 surround sound system with wall mountable satellite speakers & built-in timer is theperfect system for home cinema use. Despite it's compact size it delivers superb sound quality & can be easily connected to your computer via the outputs on your sound card (5.1 channel sound card required) or any compatible DVD player with 5.1 analogue channel (AC-3) outputs. ** Please note** In order to have true 5.1 Surround sound a Digital to Analog 5.1 Audio Adapter Sound Decoder is needed. Without this adapter only 5.1 Stereo is produced.
