Sound Devices A20-NEXUS-GO Wireless Receiver, 4 channels, SpectraBand + VHF

If you need rock-solid transmission and long-range wireless control on set and in the field, you need the Sound Devices A20-Nexus Go receiver. The multi-channel half-rack receiver fits easily in your bag and offers 4 channels of true diversity wireless that can be expanded up to eight via software licensing (sold separately). Utilizing the SpectraBand, the A20-Nexus Go presents an expansive 470 to 1525 MHz tuning range so you'll always have open channels to choose from, even when traveling internationally. You'll have full control over the corresponding A20-TX transmitters thanks to SoundDevices' integrated NexLink technology. Adjust transmitter levels remotely from the receiver using GainForward and monitor the on-set RF environment in real time without interrupting production. NexLink AutoAssign also makes it quicker and easier to get up and running on-set by scanning and logging available clean frequencies and pushing them to the transmitters in seconds. The beautiful 6.2" color OLED array provides touch control and at-a-glance verification of all your critical functions in any light. And if you need to transition to a rack or cart, the compact A20-Nexus Go will save space and money thanks to its convenient half-rack design.
