5.1 Two Channel
This Effect mixes Dolby Digital 5.1 information for two-channel play-
back. These soundtracks can be recorded onto two-channel formats, or
played back through left and right front speakers. The mix is designed
to play back with full surround when decoded through Logic 7. In mixing
a film with very heavy use of the Low Frequency Effects Channel, it may
be desirable to lower LFE MIX LEVEL.
