What is Dolby Digital 5.1 Surround Sound?

Dolby Digital 5.1 Surround Sound creates a theatre quality sound experience through left, center, right, left surround, and right surround speakers - plus a sixth speaker for those powerful low-frequency effects that are felt more than heard in movie theatres. This is often known as the subwoofer.

Dolby Digital 5.1 Surround Sound is available on broadcaster-selected programmes with Freeview via UHF aerial.
