Audio Adjust
Reverb Level This setting allows you to adjust the depth of acoustic reverberation to match the playback source material, the acoustics of your room, and such other factors. Select from the three settings �Low,� �Mid,� and �High.� Reverb Time Adjust the reverb time to match the source being played back and the acoustics of the room. Select from the three settings �Short,� �Mid,� and �Long.� speaker levels and speaker distances among the front right, front left, and center speakers are matched. In order to ensure this, make sure that the settings in the Speaker Distance Sub-menu and Level Calibration sub-menu are set correctly.) On: Select to have the center channel signal output to the center speaker. Off: Select to have the center channel signal output to the front left and right speakers (Phantom Center). Front Expander The front expander function spreads out the stereo image in front of the listener. The created stereo image is as if the front speakers have been farther apart for the feeling of a wide sound space. This is especially useful for narrow listening angles of 20 degrees or less. On: Select to turn on the front expander function to simulate a wider sound space. Off: Select to turn off the front expander function for a normal sound space. Virtual Surr Level This setting adjusts the level of the virtual surround signal. This can be set from �3 to +3 decibels. Lowering this setting can improve the sound when the de�nition is unclear or when the sound feels unnatural. Dialog Enhance If the dialog from the center channel is dif�cult to hear in the Theater-Dimensional mode, use this setting to improve the clarity. On: Select to enhance the vocal ranges of the center channel signal. Off: Select to output the center channel signal at the regular level and frequency characteristics.

Settings available when you play monaural signal
Academy Filter (DTR-6.4 only) Older monaural �lm mixes relied on high-frequency rolloff in presentation to sound properly balanced, so that excessive hiss from the grain structure of the �lm would not be heard. The highfrequency loss was typically due to a combination of optical slit loss, electrical �lters, loudspeaker response, and screen loss. Some �lms have been transferred to video without such a high-frequency rolloff, and thus sound overly bright and hissy. The DTR-6.4 includes this �Academy �lter,� which is based on contemporary playback practices for such �lms over wide-range systems. This can be set to either �On� or �Off.� Input Channel This allows you to set the way in which the stereo audio signal is output in the �Mono� listening mode. Auto L+R: Select this under normal circumstances. When the input source is center channel, this center channel is used as the monaural sound input channel. Otherwise, the left and right channels are mixed and the mixed signal is used as the monaural sound input channel. 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 the audio for different languages. Select the channel with the language you desire.

Settings available when you set �Theater-Dimensional� for your listening mode
Listening angle The listening angle is the angle subtended by the front left and right speakers as seen from the listener. The processing for the virtual surround will be based on this angle. In the Theater-Dimensional mode, the setting of 20 and 40 degrees are only for nominal purposes, so select the setting that is closest to your actual listening angle.

Center If the speaker system has a center speaker, the center channel signal can be output from the center speaker. For instance, in systems where the front left and right speakers are small, use of the center speaker may provide a better sound space and reduce the load on the front speaker. (For the proper sound�eld, it is important that the
