a. A/V Sync

If a digital signal processor is connected, there may be times when the audio and video from a DVD or LD player is not output in perfect sync. The result is where the sound and picture do not match and the sound is heard too early. In such a case, use this setting to prop- erly synchronize the audio and video. This setting can be set between 0 and 74.0 ms in 0.5 ms increments. Under normal circumstances, this can left at 0 ms. If the delay time is set between 24.5 and 74.0 ms, and upsampling is used, the delay will be fixed at 24.0 ms. Note that a change in the setting will not be displayed.

Relative Delay

b. Center, c. Surr L/R, d. Surr Back

Besides level and delay adjustments, this setting provides the ability to change or adjust the relative speaker position to fine tune the soundfield for the listener. This is accom- plished using Integra’s unique Enhanced Spatial Position- ing Algorithm. This adjustment provides 10 milliseconds of delay for the speakers, which is equivalent to moving the speaker 10 feet (3 meters) away. This adjustment is set up to provide –4.0 or +6.0 milliseconds (–4 or +6 feet/–1.2 or +1.8 meters) of adjustment to the listener’s position. Once the coarse adjustments (i.e., speaker level and distance adjustments) are made, the system is set up to provide a typ- ical or broad surround environment. By adjusting the relative position of the speakers, we are able to alter the soundfield to be more spread out (deeper) or focused (shallower).

Note:

Surr Back cannot be selected if the Surr Back/Zone 2 setting in the Surr Back/Zone 2 Sub-menu of the Hard- ware Setup Menu is set to “Zone 2.”

Setting the Low Frequency Effect Levels (LFE Level)

This sub-menu is for setting the LFE (Low Frequency Effect) levels included in Dolby Digital and DTS software.

3-5.LFE Level Setup
a.Dolby Digital:		0dB
b.DTS	:	0dB
	Quit:[SETUP]

a. Dolby Digital

The level can be adjusted to either –∞or between –10 and 0 decibels in 1 decibel increments. For Dolby Digital input source signals, the LFE level set here is used. A setting of 0 decibels is recommended for optimum performance; however, if the source is recorded with the low frequency range too strong, lower this setting as necessary.

b. DTS

The level can be adjusted to either –∞or between –10 and 0 decibels in 1-decibel increments. For DTS input source signals, the LFE level set here is used. A setting of 0 decibels is recommended for optimum performance; however, if the source is recorded with the low frequency range too strong, lower this setting as necessary.

Detailed Settings for Each Listening Mode

Mono Sub-menu

The settings of this sub-menu shown below are enabled when the listening mode is set to “Mono.”

3-6.Mono Setup

a.Academy Filter:Off

b.Input Channel

Quit:[SETUP]

a. Academy Filter

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 typi- cally 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 DTR-7.4 includes this “Academy Filter,” which is based on contemporary playback practices for such films over wide-range systems.

This can be set to either “On” or “Off.”

b. Input Channel

This allows you to set which input channel to use for monaural sound.

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 chan- nels will contain the audio for different languages. Select the channel with the language you desire.
