Changing the speaker setting to suit your speakers [BD55]
When connecting to an amplifier/receiver to enjoy multi-channel surround sound, use the following settings on this unit if they cannot be set on the
amplifier/receiver.
The settings are effective when connecting to analog 7.1 ch/5.1ch AUDIO OUT terminal.
Preparation
1 Set “Analog Audio Output” to “2ch (Downmix) + 5.1ch” or “7.1ch”.
(> 32)
A message is displayed.
2 Press [OK].
* Surround back channel is enabled only when setting “Analog Audio
Output” to “7.1ch”.
Speaker presence and size ( )
Set all the connected speakers individually.
1 Press [3, 4, 2, 1] to select the speaker icon and press [OK].
2 Press [3, 4] to select the setting and press [OK].
Icon examples:
Surround speaker (LS)
≥Large: Select when the speaker supports low-frequency
(under 100 Hz) reproduction.
≥Small: Select when the speaker does not support
low-frequency reproduction.
In order to make an ideal listening environment, settings of speaker
sizes may be automatically adjusted.
For example, if the subwoofer is set to “No”, the front speakers will
automatically be set to “Large”. (In this case, we recommend
connecting a speaker that can reproduce bass below 100 Hz.)
Delay time ( )
For optimum listening with 7.1/5.1-channel sound, all the speakers,
except for the subwoofer, should be the same distance from the
seating position.
If you have to place the center, surround and surround back speakers
closer to the seating position, adjust the delay time to make up for the
difference.
If either distance A or C is less than B (D below), find the
difference in the relevant table and change to the recommended
setting.
1 Press [3, 4, 2, 1] to select the delay time box ( ) and press
[OK].
2 Press [3, 4] to select the setting and press [OK].
