Down Mix Mode
Down mix is the process of converting multi-channel audio to a lesser number of channels. For
example, converting a 5.1ch source to stereo or converting a 7.1ch source to 5.1ch. Down mixing
allows the audio output from the player to match the exact number of speakers available in your home
theater.
The current down mix mode is displayed in the lower right corner of the speaker placement illustration.
To change the audio down mix setting, press the
ENTER button while the cursor is over the “Down Mix”
option. The following down mix modes are available:

LT/RT – Left Total/Right Total. The center and surround channels are mixed into the two front
channels according to the LT/RT matrix. A Dolby Pro Logic receiver will decode the two-
channel audio into surround audio.
x Stereo - This mode down-mixes multi-channel audio to 2-channel stereo output. For original
stereo content the output will not change. For original multi-channel content the surround and
center channels will be mixed with the left and right front channels. Recommended for use with
TV sets or stereo receiver/amplifiers.
x 5.1Ch – This mode enables 5.1ch decoded audio output. The number of actual output
channels depends on the disc. If the source content has more channels, the surround back
channels will be mixed into the surround channels.
x 7.1Ch – This mode enables 7.1ch decoded audio output. The number of actual output
channels depends on the disc. For 6.1ch contents, the left and right surround back speakers
will both output the same surround back audio channel.
