Speaker Configuration (7.1 channel
analogue audio output only)
The following settings determine how the 651/751BD’s internal
surround-sound decoder operates. They do not affect audio transmitted
over HDMI or S/P DIF/TOSLINK.
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.
Upon entering this menu, the cursor is positioned on the front left
speaker. You may use the / buttons to move the cursor. The
button moves the cursor in clockwise sequence, and the button moves
the cursor in counterclockwise sequence.
When the cursor is over the
"Down Mix" or "Exit" options, you can also use
the / buttons to highlight these options.
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 theatre system.
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 centre and surround channels are
decoded and then Matrix encoded into the two front channels. A Dolby
Pro Logic receiver can then decode the two channel audio that is output
back into surround audio.
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. Recommended for use with TV sets
or stereo receiver/amplifiers (without ProLogic decoding).
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.
7.1Ch – This mode enables 7.1ch decoded audio output. The number of
actual output channels depends on the disc.
Test Tone
Test tone is a special group of 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 is displayed in the
lower left corner of the screen.
To begin the test, press the / buttons to highlight the "Test Tone"
option, press the Enter button to change the test tone status to “On”.
Then press ARROW buttons to select a speaker, you will hear the test
sounds. To stop the test process, press / buttons to highlight the
"Test Tone" option and press the Enter button to switch the status back
to "Off". Please note these test tones only apply on multi-channel audio
outputs.
Speaker Settings
For each speaker in the home theatre system, you can set its size,
distance and trim level. To configure a speaker, 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 / 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 button
or select the "Exit" option. You can also move on to configure the next
speaker by selecting the "Next Speaker" option.
The following speaker parameters can be configured:
1. Size
The speaker size parameter sets bass filtering control for the speakers.
The bass frequency is set in the "Crossover Frequency" option of the
"Audio Processing" section of the Setup menu:
Large – Bass frequencies are passed to the speakers.
Small – Bass frequencies are not passed to the speakers to reduce
possible distortion. If a subwoofer is available, bass frequencies are
redirected to a subwoofer.
On (for subwoofer only) – Specify that a subwoofer is available.
Off – Speaker for the corresponding position does not exist. Audio for the
missing speaker is redirected to other speakers or discarded if redirection
is not possible.
NNoottee
: 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.
