Welcome to the Dolby Digital page, Dolby Digital is the standard surround
sound system used in home cinema and many public cinemas, it is the successor
to the old Dolby Pro Logic surround sound technology and is considered the
standard surround sound format. Being the standard surround sound format
has many advantages as formats such as DVD, digital television and high definition
television all use it as the standard surround sound technology so if you
are buying a new home cinema system then Dolby Digital is the surround sound
format to look for.
Allot of home cinema systems refer to Dolby Digital as 'Dolby Digital 5.1', this 5.1 refers to the amount of speakers that come with the home cinema system. Dolby Digital supports up to 5 channels (speakers) of full frequency and a sixth low frequency channel (the subwoofer) so when a home cinema system says that it supports Dolby Digital 5.1 this means that it has 5 speakers and a subwoofer. The subwoofer is refereed to as .1 because it does not offer a full frequency of sound as they only produce low frequency sound. The speakers should be situated in your room with the centre speaker either on top or below the television, the two front speakers level with the television in each front corner of the room and the rear speakers should be in each rear corner of the room.
