• Using REAR SPEAKERS
Only certain surround sound formats can be enjoyed from the TV's built-in speakers. It
may be necessary to connect rear speakers, depending on the surround mode.
Refer to page 13 for the connection of the rear speakers.
• Adjusting "REAR VOLUME"
You can enjoy dramatic sound from the built-in speakers. However, if rear speakers are
connected, a more powerful feeling of presence can be enjoyed with surround sound.
(See page 13 for connection of speakers.) If the volume is adjusted with the volume
button, the volume of the rear speakers changes together with the volume of the front
speakers.
