[Fig. 11] Playback specification for Movie program
In an environment for producing film for public performance in a theater, the playback level of the
surround speakers is not changed for 5.1 and 3-1. This means that even for 5.1, the LS and RS playback
level are to be set 3 dB lower than the other main channels (for 3-1 compatibility). For LFE, the level is
+10 dB relative to the main channels, just as for DVD-Video. (SMPTE RP 200 “Proposed SMPTE
Recommended Practice; Relative and Absolute Sound Pressure Levels for Motion-Picture Multichannel
Sound Systems”).
