Surround Sound Operation (TX-86PW100A & TX-76PW100A)
Dolby Digital and Pro Logic modes
For Dolby Digital input or Pro Logic selected in Surround mode, the following three modes of operation are available as the speaker setting: Normal, Phantom, and 3 Stereo.
Normal If front and rear speakers are connected, use Normal mode. The TV’s internal left and right speakers will produce centre speaker information. With a DTS/ Dolby Digital 5.1 input, the TV’s internal subwoofer produces the LFE speaker information. If the internal speaker is switched off (see page 18) and an external centre speaker used, the speaker must be connected using RCA cables, via an external amplifier (otherwise it will not output any sound). See page 41 for connection details.

Phantom If front left and right speakers are not connected, use Phantom mode. Left, right, and centre information will now be produced by the TV speakers. If you choose to use this mode with the internal speaker switched off and front left and right speakers connected, these must be connected using RCA cables, via an external amplifier (otherwise they will not output any sound). See page 41 for connection details.
3 Stereo This is the best mode to use if rear speakers are not connected. When using this mode, the surround information is redirected to the front left and right speakers. The TV’s internal speakers output centre information. If the internal speaker is switched off (see page
18)and an external centre speaker used, it must be connected to the TV using RCA cables, via an external amplifier (otherwise it will not output any sound). See page 41 for connection details.

Simulated Mode
Simulated modes allow various types of surround effects to be produced by mimicking both the direct sound, as heard by the audience, and the sound reflected back from the surrounding walls, ceiling and floor in places such as a discos, stadiums etc. There are three different effects to choose from, each reflecting a different atmosphere:
Setting | Appropriate sources | Effect |
DISCO | Disco, dance or jazz music | A crowded nightclub |
MOVIE | All movies or music software recorded without Dolby | Simulates a surround sound recording |
| Surround |

STADIUM | Any live sports occasion | A packed sports stadium |

Speaker Level Setup
SPEAKER LEVEL SETUP
The speaker output levels from the different options, e.g.: Left, Centre, Right, Rear right and Rear left, should be adjusted from your usual listening position, to obtain the best results. The level can be set using either the TV sound or the test signal provided. Pushing the SURROUND button switches between the test signal and TV sound.
Notes: The adjustment menu available will vary according to the mode chosen. If you have a DTS / Dolby Digital 5.1 input, and are using the internal subwoofer to produce the LFE information, you can change the LFE volume by altering the Subwoofer setting in the SOUND menu. (see page 17).
When using external stereo equipment it is advisable to set the speaker levels to
