Runco V-50HD Installation Considerations, Possible Audio Latency for Various Input Timings

Installation

Proper installation of your V-50HD/V-63HD will ensure the highest possible picture quality. Whether you are installing the V-50HD/V-63HD temporarily or permanently, you should take the following into account to ensure that it performs optimally.

To install the V-50HD/V-63HD, you will need either an optional table stand or wall-mounting kit.

If you are wall-mounting a V-50HD/V-63HD, ensure that the wall-mount bracket is installed according to the instructions included with it. The wall must be capable of supporting a redundant weight factor three (3) times the weight of the display, or be reinforced.

Runco recommends that this be done by a custom installation specialist.

3.3 Installation Considerations

Mounting the V-50HD/V-63HD on a Wall or Table Stand

1.	Use only a Runco-approved wall-mount kit or table stand that is
Note	specifically designed for your display. Refer to Parts List on
	page 4 for ordering information.
2.	If you are wall-mounting the V-50HD/V-63HD, you must attach
	the video and power cables to the display before mounting it.
Due to its extraordinarily high level of video processing performance, the DHD Controller		Audio/Video
may distribute video signals with a perceptible level of audio latency. In order to easily		Synchronization Issues

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 video displays and 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.
