-SOUND- FUNCTIONS (27AX4B, 27AX3B, 27AX0B)
will allow you to select STEREO (a stere broadcast), SA (second audio) program which
may be a secondary language, weather report, etc., or MONO (monaural sound) used
when receiving a weak stereo broadcast.
The sources received will be displayed below the channel number. The source you
select will be displayed to the left of the channel number. See example below for each
selection when both stereo and second audio are received (monaural is always
received).
• LOUDNESS
This function will improve the quality of both low and high frequency sounds when
listening at low volume levels.
• INT. SPEAKERS
This function is useful when first setting up the external speakers, or if you prefer to use
only speakers from a separate stereo system.
• SURROUND SOUND STEREO
Surround sound allows the viewer to enjoy sound which provides a feeling of "presence"
from stereo broadcasts and VCR tapes* recorded with stereo sound.
* Your VCR player must be a Hi-Fi or stereo unit. See page 32 for stereo VCR
connection (27AX3B).
* Set must be outputting stereo. (See MTS • mode: stereo (above).)
