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:

Setup

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.

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.

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.
