Ready, Set, 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, 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.

“We created A20-Nexus Go based on the feedback of our users in the field – professionals looking for a portable wireless solution that could deliver these features in a compact, easy-to-use format,” said Sound Devices CEO Matt Anderson. “A20-Nexus Go is ready to go when you are, easy to adapt to any situation, and delivers when it counts across a variety of wireless use cases.”

A kaleidoscope of compatibility in digital wireless transmitters

The A20-TX digital wireless transmitter utilizes a combination of innovative technologies and intuitive compatibility to make it a versatile, easily adaptable digital wireless transmitter. Built to offer a wider range of input compatibility than any other transmitter on the market, A20-TX serves equally well with 2- or 3-wire lavs, dynamic and phantom powered microphones, balanced line-level sources, AES digital mics, and musical instruments. A20-TX utilizes the same high headroom mic preamp from Sound Devices’ 8-Series mixer-recorders – an industry first in a digital wireless transmitter – thus guaranteeing high-quality sonic purity with a minimum of noise. Multiple A20-TX transmitters can be controlled remotely by Astral-series wireless receivers utilizing Sound Devices’ long-range NexLink remote wireless control technology, and gain can be adjusted directly from the receiver using GainForward. Ensuring long-term ease of use, A20-TX has a 12-hour battery life and is compatible with both standard and rechargeable AA batteries.
