Surround mixes of more or fewer channels are acceptable, if they are compatible, as described by the ITU-R BS. 775-1, [2] with 5.1 surround. The 3-1 channel setup (consisting of one monophonic surround channel) is such a case, where both LS and RS are fed by the monophonic signal at an attenuated level of -3 dB. [25]
For Dolby Atmos, the nomenclature differs slightly by an additional number at the end, that represents the number of overhead or Dolby Atmos enabled speakers: a 7.1.4 Dolby Atmos system is a conventional 7.1 layout with four overhead or Dolby Atmos enabled speakers. [20] [21] The simplest Dolby Atmos setup is 3.1.2, [22] the most complex one is ...
For music surround channel information is intended to be more direct as in a soundstage there would be direct noise from all around and not ambience as in a movie setting. For this reason surround speakers should not be set up to be strictly diffuse. Optimally there should be discrete surround channels for diffuse and direct effects.

The need for a center speaker to locate screen-centered sounds has been recognized since the Bell Labs experiments in stereo sound from the 1930s, and multi-channel cinema sound systems, starting with the first commercial stereophonic film (Fantasia-1941) have always included one. Post-war stereo sound in theaters initially came from separate ...
However, whereas a 5.1 surround sound system combines both surround and rear channel effects into two channels (commonly configured in home theatre set-ups as two rear surround speakers), a 7.1 surround system splits the surround and rear channel information into four distinct channels, in which sound effects are directed to left and right ...
