Welcome to the A20-Nexus
The A20-Nexus is an ultra-high performance, 8-, 12-, and 16-channel wireless microphone receiver in a compact ½-rack wide
chassis. It features 8 independent, true-diversity channels which can be expanded to 12 or 16 true-diversity channels via software
license. The A20-Nexus features NexLink, an innovative concept in wireless microphone receivers: full remote control of microphone
transmitters via an integrated, long distance RF link.
The A20-Nexus can be mounted in a standard 19-inch rack or easily placed remotely near the microphone transmitters due to its
ability to be powered by Power-over-Ethernet (PoE+), its Dante audio-over-IP, and built-in web server for control via phone, tablet, or
computer.
Additionally, the A20-Nexus can be docked to Sound Devices 833, 888, or Scorpio mixer-recorders using the A20-QuickDock
accessory, which provides convenient power, audio, and timecode connections with no additional cables. This accessory allows the
A20-Nexus to connect and disconnect from the 833, 888, or Scorpio in seconds with no tools, and be remote mounted when
desired.
