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
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
