Sound Devices has launched the A20-Nexus Go digital wireless receiver and the A20-TX digital wireless transmitter. Designed to “streamline wireless audio processes,” Sound Devices says the products bring innovative features like its proprietary SpectraBand, GainForward and NexLink technology into a versatile ecosystem of portable, rugged and wireless audio devices that function across a variety of live and recorded sound applications anywhere in the world. A20-Nexus Go is available now from MSRP $8495, and A20-TX from MSRP $2450.

A20-Nexus Go is a portable four-, six-, or eight-channel wireless receiver ideal for mobile rigs and fast-moving production. Users can scan a global tuning range of 169 – 1525 MHz with Sound Devices’ SpectraBand technology to quickly find clean and open frequencies anywhere in the world, and 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.

A20-Nexus Go Product Features:

  • Four-channel true-diversity receivers in a half-rack size (8.0” x 6.6” x 1.6” / 20.3cm x 16.8cm x 4.1cm).
  • Expandable to six or eight channels via A20-Nexus Go 2-Channel Expansion Licenses.
  • 169 MHz – 1525 MHz tuning range via SpectraBand Technology.
  • NexLink: integrated, long-distance remote control of all wireless transmitters, including group power on/off.
  • AutoAssign: automatic deployment of clean frequencies in seconds.
  • Integrated Real-Time Spectrum Analyzer (RTSA) and scanning for intuitive frequency coordination.
  • Flexible powering: via DC input, 8-Series, or AC mains (with optional adapter).
  • DB-25 connector for eight channels of mic, line or AES outputs.
  • Wide, 6.2” color OLED array with touch for control and monitoring.

The A20-TX digital wireless transmitter utilizes a combination of 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 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.
