Welcome to the A20-Nexus Go
The A20-Nexus Go is an ultra-high performance, multichannel wireless microphone receiver in a compact ½-rack wide chassis. It
features 4 independent, true-diversity channels that can be expanded to 6 or 8 true-diversity channels via software license. The
A20-Nexus Go 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 Go is ideal for use in a portable bag setup or mounted in a standard 19-inch rack. Additionally, the A20-Nexus Go
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 Go to connect
and disconnect from the 833, 888, or Scorpio in seconds with no tools.
