Runco XP-50DHD, XP-103DHD 2. Possible Audio Latency for Various Input/Output Timings, Audio/Video

Installation

Audio/Video ➤	Due to its extraordinarily high level of video processing performance, the DHD Controller
Synchronization Issues	may distribute video signals with a perceptible level of audio latency. In order to easily
	solve this issue, Runco recommends using the DHD Controller with a high-quality audio
	receiver that has the ability to effectively synchronize audio and video signals.
	Most mainstream audio receiver/switchers have the ability to synchronize the audio and
	video to the Advanced Television Systems Committee (ATSC) prescribed tolerances.
	According to the ATSC, the sound program should never lead the video program by more
	than 15 milliseconds, and should never lag behind the video program by more than 45
	milliseconds.
	In addition, many A/V receivers introduce additional latency that needs to be
	compensated for during the installation. Table 3-2shows the amount of possible audio
	latency given different signal input timings.
