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.
