(Note: In order to gain an extra 10dB of headroom on the low frequency effects (LFE) channel, Dolby
specifies that this channel be recorded 10dB lower than the 5 main channels. This 10dB lower level is made up in
the playback chain to restore the correct 5 channel to .1 channel balance. For additional information please see
the "Dolby Digital Professional Encoder Manual" which is available from the Dolby website. (www
