Notes on the output of Dolby Digital (AC-3) source
signals
When Dolby Digital (AC-3) encoded sources are played back
through this unit, the output method changes automatically
according to the information recorded on the source and the
settings of this unit.
• When playing a source encoded with discrete
information
If the "DOLBY" sound field is set to ON: The
DISCRETE indicator lights up and the number of
channels recorded in the source are decoded and output
directly.
If a sound field (other than "ACOUSTIC" or
"KARAOKE") is set to ON: The DISCRETE indicator
lights up and the number of channels recorded in the
source are decoded. The effects provided by each sound
field are then added to each channel before the sound is
output.
If the "ACOUSTIC" soundfield is selected or the
sound field is set to OFF: The source signal is
downmixed to 2 ch (Left and Right) stereo before
output. When "ACOUSTIC" is selected equalizer (EQ)
adjustments can be performed.
• When playing a source encoded with Dolby Pro Logic
information
If the "DOLBY" sound field is set to ON: "PRO
LOGIC” appears in the display, the sound is decoded
using Pro Logic formula and output.
If a sound field (other than "ACOUSTIC") is set to
ON: The effects provided by each sound field are added
to each channel before the sound is output.
When the sound field genre is MOVIE (except for
MONO MOVIE) or 3D the sound is decoded using the
Pro Logic formula and "PRO LOGIC" appears in the
display.
If the "ACOUSTIC" sound field is selected or the
sound field is set to OFF: The source signal is
downmixed to 2 ch (Left and Right) stereo before
output. When "ACOUSTIC" is selected equalizer (EQ)
adjustments can be performed.
For the list of sound fields, see page 13.

Use discs with the PRfr?S logo. In order to enjoy Dolby
Digital (AC-3) playback you must use discs bearing this
logo.
Note on the "KARAOKE" mode
The KARAOKE mode is designed to reduce vocal tracks
positioned in the center of 2 channel sources. Therefore,
5.1 channel Dolby Digital (AC-3) sources must be
downmixed to 2 channels before the KARAOKE effect can
be applied. Consequently, the "DISCRETE" indicator does
not light when you select KARAOKE while inputting 5.1
channel Dolby Digital (AC-3) sources.
