Dolby

LRCS
LRCS refers to Left Right Center Surround, where the surround speaker is center-rear positioned. This is the original surround format that first appeared as Dolby Stereo in cinema and later as the home cinema format Dolby ProLogic.

5.0
This is the same as 5.1 (see below) but without the LFE channel. The LFE channel is optional in 5.1 and if you do not plan to use it, you might find this option more convenient.

5.1
This format is one of the most popular in cinema and DVD. In its various cinema and DVD encoding implementations (established by different manufacturers) it is referred to as Dolby Digital, AC-3, DTS and MPEG 2 Multichannel. 5.1 has 1 center speaker (mainly used for speech) and 4 surround speakers (for music and sound effects). Additionally a subchannel (LFE – Low Frequency Effects) with lower bandwidth is used for special low frequency effects.
