To enjoy a video source with the Dolby Pro
Logic Surround or Dolby Digital (AC-3)
decoded
When you select the program No. 1, 2 or 3, and the input
signal of the source is 2-channel stereo, Dolby Pro Logic
Surround is decoded. When some program is selected and the
input signal of the source is encoded with the Dolby Digital (AC-
3), Dolby Digital (AC-3) is automatically decoded.
* The following indicators on the display panel show you what
sound processing is being made.
* In addition, for the program No. 1, 2 and 3, the name of the
program on the display panel or the monitor screen will change
according to the type of decoding. (For details, refer to page
40.)
Note
If the input signals of source encoded with the Dolby Digital (AC-
3) are in 2-channels only, the sound processing for them is similar
to that for analog or PCM audio signals.
To cancel the effect sound
The EFFECT button on the front panel and the EFFECT ON/OFF
key on the remote control transmitter make it simple to compare
the normal stereo sound with the fully processed effect sound.
To cancel the effect sound and monitor only the main sound,
press the EFFECT ON/OFF key or the EFFECT button. Press
the EFFECT ON/OFF key or the EFFECT button a second time
to restore normal operation.
Notes
●
If the effect sound is canceled when signals encoded with the
Dolby Digital (AC-3) are input to this unit, signals of all
channels are mixed and are output from the main speakers.
●
If the EFFECT button or the EFFECT ON/OFF key is pressed
to turn effect sounds OFF when the Dolby Digital (AC-3) is
decoded, it may happen that sound is output faintly or not
output normally depending on a source. In that case, press the
EFFECT button or the EFFECT ON/OFF key to turn effect
sounds ON, or use input signals not encoded with the Dolby
Digital (AC-3).
