Listening to surround sound
“Surround sound” is a sound reproduction process resulting
in a three-dimensional aural experience that is a combina-
tion of “surround ‘effect sound” and “normal sound”,
delivered from both of left and right channels at: the same
time.
@ The surround effect sound is possible only when the
sound source being listened to is stereo. (In the case of
monaural sound source, no sound from the speakers
connected to the external speaker terminals will be out-
put. Therefore, listening to surround sound is impossible.)
@ Set the marker of the scale of the BALANCE adjustment
made to its center position using the FUNCTION button(s}
and/or the AV STATUS/RESET button. See page 13.
