Multichannel Audio Processing
Setup
The “Audio Processing Setup” section of the Setup Menu system allows you
to configure how the player will process audio signals before sending them
to the output. This ONLY impacts the playback of multichannel sources.
None of the settings have any impact on 2 channels sources such as CDs.
Speaker Configuration
In the Speaker Configuration menu you can configure speaker settings
such as down-mix mode, number of speakers, their distance, size and trim
level. The Speaker Configuration menu shows an illustration of the speaker
placements to assist you on properly configuring the speaker parameters.
Many of these settings apply to the UMT in the MultiChannel mode and
should not be adjusted when in the 2 channel mode.
Upon entering this menu, the cursor is positioned on the front left speaker.
You may use the LEFT/RIGHT ARROW buttons to move the cursor. The
RIGHT ARROW button moves the cursor in clockwise sequence, and the
LEFT ARROW button moves the cursor in counterclockwise sequence.
When the cursor is over the “Down Mix”, “Test Tone” or “Exit” options,
you can also use the UP/DOWN ARROW button to highlight these options.
Down Mix Mode
In the Stereo Mode, the down mixing is automatic so please do not change
but leave set to 7.1 Ch. In Multichannel Mode, Center defaults OFF. If
you want the center channel you must turn it on.
Speaker Settings
For each speaker in the home theater system, you can set its size, distance
and trim level. Again, in the Stereo Mode, all speaker sizes should be left
large and no trim levels should be changed. Delay for the center channel
may be adjusted as the center channel is downmixed into the fronts. The delay settings will adjust the center channel in relation to the
fronts. It should match the front channels.
To configure a speaker, use the LEFT/RIGHT ARROW buttons to move the
cursor to highlight the speaker and press the ENTER button. The Speaker
Settings menu on the right side of the screen will be activated. In the Speaker
Settings menu, use the UP/DOWN ARROW buttons to select a parameter,
and then press the ENTER button to change it. To exit the Speaker Settings
menu and return to the Speaker Configuration illustration, press the LEFT
ARROW button or select the “Exit” option. You can also move on to
configure the next speaker by selecting the “Next Speaker” option.
1. Size: Please set all speakers to LARGE.
NOTE The front, surround and surround back speakers are configured as
pairs. Changes to the size of one speaker will automatically change the
other speaker of the pair.
2. Distance: The speaker distance parameters set delay control for the
corresponding audio channel. The delay is to compensate for the audio
propagation time difference caused by the placement of speakers.
Speaker distance delay is only applied if the player is decoding multi-
channel audio. Since the delay is calculated based on the distance difference from each speaker to the listener’s position, it is important
to set the distance for the front speakers first and then the other speakers. Any time you change the distance of the front speakers,
the distance of the other speakers will be automatically adjusted to maintain the same distance difference.
Because the Center is phantom, it should be set to the same distance as the fronts. The front distance can be adjusted to match the
video delay, which varies among displays.
3. Trim Level: The trim level should not be adjusted.
Other Audio Processing Settings
In addition to Speaker Configuration, Crossover Frequency and Dynamic Range Control are audio processing settings that can be configured:
1. Crossover Frequency: Not relevant in this case as speakers are set to LARGE.
