Down Mix Mode
Downmixing 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. Downmixing allows
the audio output from the player to match the exact number of speakers available in your home theatre.
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:
x LT/RT – Left Total/Right Total. The centre 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
centre channels will be mixed with the left and right front channels. This is 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.
Test Tone
Test tones are artificially-created sounds that are used to test your audio speaker system and help to identify
any wiring faults. By default the
Test Tone is set to Off , with the status displayed in the lower left corner of the
screen.
Please note these test tones only work with the multi-channel analog audio outputs and are only suitable for
channel identification purposes. For comprehensive speaker configuration, we recommend using the dedicated
test tones found on professional audio calibration discs.
To begin the test, press the ARROW buttons to highlight the Test Tone option, and press the Enter button to
change the test tone status to On . Press the ARROW buttons to select a speaker, and you will hear the test
sounds. To stop the test process, press the ARROW buttons to highlight the Test Tone option and press the
Enter button to switch the status back to Off .
