Expanded Stereo

Your TV includes an Expanded Stereo feature which adds

greater depth and dimension to stereo broadcasts. Your TV

electronically increases the audio separation perception of

the speakers so you perceive an “expanded” more spacious

stereo sound effect.

Although you can easily turn the expanded stereo feature

on and off as desired, you may prefer to leave it turned on.

That way your TV will automatically process and expand

the stereo signals whenever a stereo broadcast is received

(or whenever a stereo tape is played through a stereo VCR

connected to the TV’s audio/video jacks labeled

INPUT).

Because this feature expands stereo sound, it processes

only stereo signals. If a TV program is broadcast in mono

instead of stereo, your TV will automatically reproduce

monaural audio. You will not be able to hear Expanded

Stereo because expansion has no effect on monaural audio.

Stereo expansion enhances the ambience of music and

program material. Dramatic effects of spatial enhancement

can be experienced with music. Talk shows with

background crowd noise also benefit from expansion by

engulfing the listener in a wider sound field than would be

experienced without expanded stereo. The effect will vary

with program material.

The perception of greater stereo separation is created by

cancelling the cross-coupled sound from the right speaker

that arrives at the left ear (and the left speaker that arrives

at the right ear). Like stereo headphones, stereo expansion

isolates the left and right signals that arrive at the ears. As

a result, the speakers seem to be farther away from the TV.

Notes: The Expanded Stereo feature will have no effect unless the

program is broadcast in stereo.

When the Expanded Stereo feature is turned on, some sound will be

heard from each speaker regardless of the

BALANCE control setting.

Resetting the Audio Function to Hear Expanded Stereo

with or without remote

1 Press the MENU button repeatedly to select the AUDIO MENU

and then press + to display the audio menu.

2 Press the

MENU button repeatedly to select the EXPAND STEREO

display.

3 Press either + or – to turn on Expanded Stereo. Each time

you press the + or – button, the on-screen display will change

from

ON to OFF, etc.

To Hear Expanded Stereo

1 The STEREO/SAP function must be set to STEREO. You will not

hear expanded stereo if this

function is set to

MONO or

SAP. Details are on page 13.

2 The EXPAND STEREO function

must be set to

ON. You will

not hear expanded stereo if

this function is set to

OFF.

3 A stereo signal must be

present. You will not hear

expanded stereo on TV

programs if the TV station

is broadcasting monaural

audio. You can, however, hear expanded stereo if you play a

stereo tape on a stereo VCR that is connected to the TV’s

audio/video jacks labeled

INPUT.

Normally, you can leave the

STEREO/SAP function set to

STEREO and the EXPAND STEREO function set to ON. Your TV

will then automatically produce either expanded stereo or

monaural sound, whichever is broadcast.
