1.2
Location of LA-5180
The Linear Acoustic LA-5180 Metadata Frame Synchronizer and Generator can be located
anywhere. Typical locations include audio mixing facilities or rooms, remote outside
broadcast (OB) trucks, transmission facilities, playout facilities, satellite facilities, etc... In
many cases, it may be located near AC-3 encoders such as a Dolby DP-569. Anywhere that
an error-free metadata signal is required is an ideal location for an LA-5180. As it will likely
be in a transmission environment, dual redundant power supplies and hard relay bypass
are provided for trouble free operation.
1.3
Future Updates
Software updates may become available in the future to add additional features and per-
formance. Updates will utilize the Ethernet port to accomplish the installation of upgraded
software, and a loader application will be provided for this purpose.
