The A20-Nexus Go true diversity wireless receiver was made with portability in mind. It comes with four receiver channels, and can be expanded to six and eight channels via software license, without additional hardware. Need to transition to a rack or cart? The A20-Nexus Go receiver’s half-unit size will save you space there, too. It’s ready for anything.

The A20-Nexus Go receiver utilizes the unparalleled SpectraBand tuning range of 169 – 1525 MHz, allowing you the ability to find open spectrum, even in the busiest UHF TV band.

No more stopping the action on set. No more adjusting the transmitter gain on the talent. You can set your levels and make adjustments at your A20-Nexus Go receiver and not at the transmitter with GainForward.

By utilizing the NexLink protocol, the A20-Nexus Go receiver has full long-range remote control of transmitters, even in the presence of on-set 2.4 GHz interference.

With NexLink and the A20-Nexus Go receiver’s integrated RTSA (Real Time Spectrum Analyzer), you can visually monitor the changing RF environment without interrupting the audio or a shoot.

Save time on set. The AutoAssign function automatically scans the current tuning band for clean frequencies and assigns them to multiple channels. The clean frequencies are then automatically pushed to transmitters linked to the NexLink protocol. This is all done with one button in mere seconds.
