About 6. 1 channel matrix decoding Enjoying Surround Sound Some movies released after summer 1999 added a new channel to the preexisting 5. 1 channels. The new channel added speakers behind the listening position. In the movie theaters, these speakers are placed on the rear wall, on each side of the projection room's window. The 6. 1 channel system used in the movie theaters is called Dolby Surround EX system. However, to record on movie film, this 6. 1 channel is converted to 5. 1 channel using matrix encoding, and the same number of channels are used as Dolby Digital and DTS recordings. Recordings on DVD also use the same signals. A lot of movie theaters screen movies with matrix encoded 5. 1 channel signals and this is not unnatural to the ears.
