Once you have entered the distance to the nearest speaker, the DC-1 will automatically calculate the maximum allowable distance. The display will show all of the speakers, each with a default distance setting equal to your nearest speaker. Use SELECT and ▲ and ▼ to highlight and enter actual distances for each speaker. The DC-1 rounds off distance settings into discrete steps – choose the closest step to the actual distance in these cases. If a speaker distance is further than the DC-1 can accommodate, set it to the maximum allowable distance. (This will vary, depending on your intial entry for NEAREST SPKR.)
A/V Sync Delay compensates for the delay that occurs when a video processor, such as a scan converter, is used with the DC-1. Most of these processors alter the original audio/video timing relationship by adding delay to the video signal as it is processed. A/V Sync Delay applies a corresponding delay to the audio signal to restore the original audio/video timing relationship. It can also be used to compensate for poorly mastered source material.
If your video material appears to be out of sync, engage A/V Sync Delay in the LISTENER POSITION menu. With a video source running, adjust the delay along its range with ▲ and ▼.
Note that it is best to use a non-film source when setting A/V Sync Delay, as film dialog added in post production may have poor timing relation- ships.
Panorama works by canceling the sound going from each speaker to the opposite ear. Its effectiveness is highly dependent on the geometry of your front loudspeakers, the room and your listening position. The correct timing of the canceling signal varies with the relative angle between your main speakers.
Find a mono source, such as an announcer on FM radio or a mono film, and listen for a tightly focused center image of speech or singing. If the image is off-center, adjust the DC-1’s input balance controls. (The more centered the monaural image, the better Panorama will work.)
Select CALIBRATE PANORAMA from the Listener Position menu to display a sub-menu that allows you to turn on a calibration noise source, configure the speaker angle, and adjust the listener position.
