According to Sony, the Surround Sound System utilises cutting-edge technologies, including Sony's S-Force PRO Front Surround Sound that generates rich realistic surround sound over one front speaker and presumably means gamers, keen to keep things minimal, can have one less box under the television.
The Surround Sound System comes with two audio inputs − an optical audio input for connecting high-end entertainment systems including PS3, and an analogue audio input for connecting portable devices like the PSP system to enjoy listening to music in the living room.
