Description

Overview

Sound Devices’ A20-Nexus Go is a half-rack wideband true diversity receiver with remote control and real time spectrum analysis, It ships with four receiverchannels and is expandable via software license.

Delivery includes A20-Nexus Go, (2) A20-Monarch SpectraBand antennas with articulated arm mounting clamps and cables, and (2) 2.4 GHz antennas for remote control with mounting brackets and cables.

The A20-Nexus Go receiver has an advanced set of features from the Sound Devices Astral family of products, including:

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

NexLink
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.

GainForward
When using a compatible transmitter with GainForward architecture, you can set your levels and make adjustments at your A20-Nexus Go receiver without touching the transmitter.

AutoAssign
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.

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

Flexible Form Factor
Thanks to its half-rack size, the A20-Nexus Go is equally at home in a rack, in a bag, or docked to an 8-Series recorder with the A20-QuickDock (sold separately) for a cableless kit.
