IQMUX30

3G/HD/SD-SDI Multiplexer for 8 AES/EBU Audio Streams

The IQMUX30 provides 16-channel digital audio embedding for 3G-SDI 3 Gb/s, 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 general digital ingest module where any digital audio source signal can be catered for, even combinations of embedded and external digital audio.
