AUTO
When this mode is selected, the unit determines
whether the digital input signal is Dolby Digital,
Dolby Digital Surround EX, Dolby Digital Plus, Dolby
TrueHD, DTS-HD, DTS, DTS-ES, DTS 96/24 or PCM
audio.
Surround EX & DTS-ES will operate for multichannel
sources that have a Dolby Digital Surround EX or
DTS-ES auto trigger fl ag in the digital signal.
When a Dolby Digital or DTS signal is input, the
number of channels for which the corresponding
signal is encoded will be played.
Inputting a Dolby Digital two channel signal with
Dolby surround status automatically subjects that
signal to Pro Logic IIx movie processing before
play.
PCM 96 kHz source material can be played in this
mode.
Notes
• When you use this mode with certain DVD and
CD players, performing operations such as skip
or stop may momentarily interrupt the output.
• When the signal is not decoded, the mode is
changed to AUTO mode automatically. See page
83 to confi rm the available decoding modes.
SOURCE DIRECT
In the Source Direct mode, the tone control circuit
Acoustic EQ. and bass management confi guration
are bypassed for full-range frequency response and
the purist audio reproduction.
Notes
• Speaker size is set to Front L/R = Large, Center
= Large, Surround L/R = Large and Subwoofer
= Yes automatically. Tone controls, equalizer and
additional processing are deactivated.
• When you use this mode with certain DVD and
CD players, performing operations such as skip
or stop may momentarily interrupt the output.

(VIDEO, S-VIDEO, COMPONENT VIDEO and HDMI)
and turning the FL display off.

EX/ES
This mode provides 6.1 channel surround for Dolby
Digital EX, and DTS-ES-encoded source material
such as DVD.
This mode cannot be used when an analog input has
been selected.
Dolby Digital EX
In a movie theater, fi lm soundtracks that have been
encoded with Dolby Digital Surround EX technology
are able to reproduce an extra channel which has
been added during the mixing of the program.
This channel, called surround back, places sounds
behind the listener in addition to the currently
available front left, front center, front right, surround
right, surround left and subwoofer channels.
This additional channel provides the opportunity
for more detailed imaging behind the listener and
brings more depth, spacious ambience and sound
localization than ever before.
Dolby Digital EX is not available in systems that do
not have without surround back speaker(s).
DTS-ES (Discrete 6.1, Matrix 6.1)
DTS-ES adds the surround center channel audio to
the DTS 5.1 channel format to improve the acoustic
positioning, and makes acoustic image movement
more natural with the 6.1 channel reproduction.
This unit incorporates a DTS-ES-decoder, which
can handle DTS-ES Discrete-encoded and DTS-ES
Matrix-encoded program sources from DVD, etc.
DTS-ES Discrete 6.1 features digital discrete
recording of all channels, including the surround back
channel(s), and higher quality audio reproduction.
DTS-ES is not available in systems that do not have
surround back speakers.
