Sound Devices Announces has announced its new A20-Nexus Go True-Diversity Wireless Receiver and A20-TX Digital Wireless Transmitter.
The A20-Nexus Go true-diversity digital wireless receiver and the A20-TX digital wireless transmitter are the latest additions to the Astral series of wireless audio products. They were designed to streamline wireless audio processes and bring innovative features like Sound Devices’ proprietary SpectraBand, GainForward, and NexLink technology into a versatile ecosystem of portable, rugged, and easy-to-operate wireless audio devices that function across a variety of live and recorded sound applications anywhere in the world.
A20-Nexus Go
Designed for the on-the-move production sound professional, A20-Nexus Go is a portable 4-, 6-, or 8-channel wireless receiver ideal for mobile rigs and fast-moving production. Users can scan an industry-leading global tuning range of 169 – 1525 MHz with Sound Devices’ SpectraBand technology to quickly find clean and open frequencies anywhere in the world. They can also easily assign transmitters to those frequencies using A20-Nexus Go’s AutoAssign function, adjust transmitter gain as needed directly from the receiver using GainForward, and keep tabs on any potential RF difficulties with A20-Nexus Go’s integrated Real Time Frequency Analysis (RTSA) functionality. Combined, this makes A20-Nexus Go a versatile wireless hub packed with forward-thinking features that can replace multiple devices in any crowded production sound bag.
The A20-Nexus Go was created based on the feedback of Sound Devices users in the field. Professionals were looking for a portable wireless solution that could deliver these features in a compact, easy-to-use format.
