About the Listening Modes
With its built-in surround-sound decoders and DSP pro-
grams, the TX-NR901 can transform your home listen-
ing room into a movie theater or concert hall.
To get the most from surround sound, it’s important that
you install and configure your speakers correctly. See
“Connecting Your Speakers” on page 23 and “Speaker
Settings” on page 40 for information.
Direct
The selected input source is output by the front left and
right speakers only, with minimal processing for a pure
sound.
Pure Audio
As an extension of Direct mode, this mode turns off the
display, turns off the power to the video circuitry, and
minimizes any other possible noise sources, providing a
high fidelity sound that’s true to the original. (Since the
power to the video circuitry is turned off, no video sig-
nals will be output.)
Stereo
The selected input source is processed as a stereo signal
and output by the front left and right speakers and the
subwoofer.
Mono
Use this mode when watching an old movie with a mono
soundtrack or to select multilingual soundtracks
recorded in the left and right channel of some movies. It
can also be used when playing a DVD or other source
with multiplexed audio, such as a karaoke DVD.
T-D (Theater-Dimensional) or
With this mode you can enjoy a virtual 5.1 surround
sound even with only two or three speakers. This works
by controlling how sounds reach the listener’s left and
right ears. Good results may not be possible if there’s too
much reverb, so we recommend that you use this mode
in an environment with little or no natural reverb.
Dolby Pro Logic II Movie
Use this mode with DVDs and vid-
eos that bear the Dolby Surround
logo or TV programs that feature Dolby Surround. You
can also use this mode with stereo movies or TV pro-
grams and the TX-NR901 will create a 5.1 surround mix
from the 2-channel stereo.
Dolby Pro Logic II Music
Use this mode to add 5.1 surround to stereo sources such
as music CDs and DVDs.
Dolby Digital
With this format you can experience the
same superb sound that you get at a movie
theater or concert hall. Use this mode with DVDs that
bear the Dolby Digital logo.
Dolby Digital EX
With an added surround-back channel,
this 6.1 channel format offers a heightened
sense of space, for added realism with moving sounds,
such as those that rotate 360 degrees or pass overhead.
Dolby Digital EX material can also be played on conven-
tional 5.1 channel systems, in which case the surround-
back channel audio is divided between the surround left
and right channels. Use this mode with DVDs that have
a 5.1-channel soundtrack and bear the Dolby Digital
logo.
DTS
This digital surround format offers a sur-
round sound experience with exceptional
fidelity. It uses compressed digital audio
data, with six completely separate channels
(5.1), and the ability to handle large amounts of audio
data while remaining faithful to the original. DTS pro-
vides very high-quality sound. You’ll need a DTS com-
patible DVD player in order to enjoy DTS material. Use
this mode with DVDs, LDs, or CDs that bear the DTS
logo.
DTS-ES Discrete
This is DTS with an added surround back
channel for 6.1 surround sound. Use it with
program material recorded in DTS 6.1 format. With the
additional surround back channel, this format offers 6.1
fully independent digital channels, providing a realistic
sense of movement and space. Use it with program mate-
rial recorded in DTS 6.1, such as CDs, DVDs, or LDs
that bear the DTS-ES logo.
DTS-ES Matrix
This is DTS with an added surround back
channel for 6.1 surround sound. Use it to
provide 6.1 channel surround playback
with program material recorded in DTS 5.1
format. Since DTS 5.1 program material
contains surround back channel informa-
tion, all channels can be reconstructed for 6.1 surround
playback. Use this mode with CDs, DVDs, or LDs that
bear the DTS-ES or DTS logo.
