Listening Mode Setup

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.
