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 setting 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,” “Academy,” 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 theaters 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 response, and screen loss. Some films have been
transferred to video without such a high-frequency rolloff, and
thus sound overly bright and hissy. The TX-DS989 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 speakers to output
the sound meant for the surround speakers during 5.1-channel
output when seven speakers are connected to the TX-DS989.
Surround L/R: This outputs the sound to the surround left and
right speakers as normal and outputs nothing to the surround
back left and right speakers.
Surround Back: This outputs the sound to the surround 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 surround
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 effects 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 direct 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 acoustic
reverberation 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.
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 setting of 20 and 40
degrees are only for nominal purposes, so select the setting that is
closest to your actual listening angle.
