Channel Mode
1/0 Mono: Single front channel, no surround channels. For a two-channel system, the
signal is reproduced equally from both channels attenuated 3 dB. For a
5.1-channel system, the signal is reproduced from the center channel
(L, R, LS, RS channels are not used).
2/0 Stereo: Left and right channels, no center or surround channels. For a two-channel
system, the signal is reproduced equally from the L, R channels. For a 5.1-
channel system, the signal can either be reproduced from only the L, R
channels or, optionally, from L, C, R, S (see Dolby Srnd Mode).
3/0: Left, center, and right channels, no surround channels. For a two-channel

is reproduced equally from the L, R channels; the surround channel is
