Description
The Linear Acoustic LA-5291 Professional Audio Encoder allows you to create an exciting and immersive Dolby Atmos® experience via a Dolby Digital Plus JOC bitstream for production workflows, platforms, and delivery streams that do not require Dolby AC-4. The LA-5291 offers decoding, encoding, and transcoding to and from PCM and select Dolby® coded formats for up to 16 audio channels.
Features:
- Decoding from Dolby ED2 to PCM
- Transcoding from Dolby ED2 to Dolby Digital Plus and Dolby Digital Plus JOC
- Encoding PCM to Dolby Digital Plus and Dolby Digital Plus JOC
- 3Gb/s HD/SD-SDI and AES-3 I/O
- AES67 I/O in support of SMPTE ST 2110-30 and -31 workflows
- Optional Quad-Link 3Gb/s SDI I/O for supporting 4K video workflows, or optional MADI I/O (mutually exclusive options)
- Dual internal redundant auto-ranging power supplies
- Browser-based remote control
Supporting Today’s Dolby Atmos Workflows
While emerging standards such as ATSC 3.0 continue to advance and provide improved immersive audio for OTA broadcast, the amount of cinematic and live content produced in Dolby Atmos continues to grow as well reaching consumers via Blu-ray Disc, satellite, cable, and streaming services. The workflow required to create, transport, and deliver that content to viewers at home can be complex, requiring the ability to work with PCM, Dolby ED2, Dolby Digital Plus, and Dolby Digital Plus JOC formats - tasks for which the LA-5291 was purpose-built.
Equally at Home for Contribution and Distribution
The LA-5291 integrates well into remote and OB trucks for encoding multi-channel PCM audio into Dolby Digital Plus or Dolby Digital Plus JOC for distribution. Further downstream, it can transcode Dolby ED2 directly to Dolby Digital Plus and Dolby Digital Plus JOC, and can encode PCM to Dolby Digital Plus and Dolby Digital Plus JOC for final distribution.
