Description listening mode parameters
Subwoofer
Set this to “Off” if you are not using a subwoofer (even if
one is connected). If “No” is selected for the Subwoofer
setting in the Speaker Config sub-menu, then this set-
ting will not appear.
Re-EQ/Academy
Depending on the listening mode, you can either turn
Re-EQ on or off, or you can select “Re-EQ,” “Acad-
emy,” or “Off.”
Re-EQ: Re-EQ (re-equalization) takes the edginess
or “brightness” out of your home cinema sound to
compensate for the fact that sound mixed for the-
aters may sound too bright when played back
through speakers in the home environment.
Academy: Older monaural film mixes relied on high-
frequency rolloff in presentation to sound properly
balanced, so that excessive hiss from the grain
structure of the film would not be heard. The high-
frequency loss was typically due to a combination
of optical slit loss, electrical filters, loudspeaker re-
sponse, and screen loss. Some films have been
transferred to video without such a high-frequency
rolloff, and thus sound overly bright and hissy. The
DTR-9.1 includes this “Academy filter,” which is
based on contemporary playback practices for
such films over wide-range systems.
On: Select to turn on the Re-EQ.
Off: Select to turn off both the re-equalization and
Academy filters.
Input Channel
This allows you to set which input channel to use for
monaural sound.
Auto L+R: Select this under normal circumstances for
output from both the left and right speakers.
Left/Right: You will need to select either left or right
when playing a video source that contains bilingual
data. In such a case, the left and right channels will
contain different language. Select the channel with
the language you desire.
Output Channel
This allows you to set which output channel to use for
monaural sound. If “None” is selected for the Center
Speaker setting in the Speaker Config sub-menu, then
this setting will not appear.
L+R: The monaural sound is split between the left
and right channels.
Center: The monaural sound is output from the front
center channel.
Digital Upsampling
Digital upsampling processes the input digital signal
and converts its digital sampling frequency to twice the
current frequency for an even further detailed sound
reproduction. This can be set to either “On” or “Off.”
Surround Speakers
This setting allows you to decide through which speak-
ers to output the sound meant for the surround speak-
ers during 5.1-channel output when seven speakers are
connected to the DTR-9.1.
Surround L/R: This outputs the sound to the surround
left and right speakers as normal and outputs noth-
ing to the surround back left and right speakers.
Surround Back: This outputs the sound to the sur-
round back left and right speakers and outputs
nothing to the surround left and right speakers.
Sur L/R+Back: This outputs the sound to both the sur-
round left and right speakers and the surround back
left and right speakers.
Front Effect
Some live recordings contain acoustic reverberation.
When you play these sources, more reverberation will
be applied by the DSP, creating too much reverb ef-
fects and the sound loses frame or presence. In this
case, set this setting to “Off.” No reverberation from the
DSP will be applied to the sound output from the three
front channels, so the sound source is be played as it is
without any further reverberation.
Reflect Lvl
This parameter allows you to adjust the strength of di-
rect sound reflections to match the playback source
material, the acoustics of your room, and such other
factors. This can be set between -5 and +5 decibels in
1-decibel increments.
Reverb Lvl
This parameter allows you to adjust the depth of acous-
tic reverberation to match the playback source mate-
rial, the acoustics of your room, and such other factors.
This can be set between -5 and +5 decibels in 1-decibel
increments.
Room Size
This parameter allows you set virtual hall size to simulate
for each surround mode. You can choose from
“Large,” “Mid-Large,” “Middle,” “Mid-Small,” or
“Small.”
Listening angle
The listening angle is the angle subtended by the front
left and right speakers as seen from the listener. The set-
ting of 20 and 40 degrees are only for nominal pur-
poses, so select the setting that is closest to your actual
listening angle.
