Linear Acoustic LA-5300 

 

Broadcast Audio Processor

 

 

Preliminary Quick Start Guide  

 

Introduction  

 

The roll-out of ATSC 3.0 presents a unique set of requirements and opportunities for 
television broadcasters, including many enhanced audio capabilities. The Linear 

Acoustic LA-5300 provides a single 1RU solution for audio loudness control, 

upmixing, AC-4 decoding for watermarking, bitstream analysis, and monitoring, 

transcoding of Dolby® Digital and Dolby Digital Plus sources to AC-4, as well as 
Dolby AC-4 encoding of PCM. As ATSC 3.0 adoption grows, support for additional 

features including immersive and object-based audio, interactive consumer control, 

personalized audio, and multiple presentations within a single stream will be 
incorporated into the LA-5300 via software updates.
