IQBRK30
3G/HD/SD-SDI Remultiplexer for Four AES/EBU Audio Streams
The IQBRK30 provides 8-channel digital audio de-embedding and re-embedding for 3 Gb/s SDI, HD-SDI 1.5 Gb/s or SD-SDI 270 Mb/s signals. Able to select any of the 16 embedded channels, audio processing features include audio delay, gain, invert and channel level routing, while video delay and a video proc amp are also included in the feature set. Ideal for breaking out embedded audio to AES-only devices for processing then re-ingesting the resulting feeds back into the SDI domain.
Why should you choose this module?
- Ideal as a re-embedder for stereo, multichannel or Dolby E AES audio applications
- Suitable for multi-lingual audio applications...
