IQMUX31 3G/HD/SD 8 AES Embedder

The IQMUX31 provides 8-channel digital audio embedding for 3 Gb/s SDI, HD-SDI 1.5 Gb/s or SD-SDI 270 Mb/s signals. 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 as a small scale digital ingest module where any digital audio source signal can be catered for, even combinations of embedded and external digital audio.

FEATURES

  • 8-channel 3G/HD/SD-SDI embedder capable of embedding asynchronous or synchronous AES inputs
