Location of LA-5448
The Linear Acoustic LA-5448 Demultiplexer/Splicer is best located near network
satellite receivers or just prior to a multiplexer. In some cases, it maybe located near
AC-3 encoders such as a Dolby DP-569. As it will likely be in a transmission envi-
ronment, dual redundant power supplies and hard relay bypass are provided for trou-
ble free operation.

Future Updates
Software updates may become available in the future to add additional features and
performance. Updates will utilize the serial port to accomplish the installation of up-
graded software, and a loader application will be provided for this purpose.
