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.

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.

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
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.
