MDX-3901
12G/3G/HD 16 Channel AES/MADI Embedder/De-Embedder
The MDX-3901 is an advanced, high-quality audio processor, which can embed up to 16 audio channels from a selection between eight discrete AES and/or one MADI signal into 12G/Quad Link 3G/3G/HD SDI signals or de-embed up to 16 audio channels into eight AES and one MADI signal from a 12G/Quad Link 3G/3G/HD SDI signals.
