About Sound Devices A20-Nexus Go

An Advanced A20-Nexus Go 4-Channel Digital True Diversity Wireless Receiver, the A20-Nexus Go, is a sophisticated piece of high-tech audio equipment designed for professionals in need of reliable, multi-channel wireless audio reception. This state-of-the-art receiver is not only portable but also highly adaptable, with the capability to expand from four to six or eight channels through a simple software license upgrade, negating the need for additional hardware.

Crafted for those who require high-quality audio reception without the burden of heavy equipment, the A20-Nexus Go is ideal for on-the-go bag work. Its compact half-unit size ensures it fits seamlessly into any rack or cart setup, saving valuable space while maintaining top performance.

The A20-Nexus Go receiver boasts an innovative feature set that is characteristic of the Astral family of products. One of its most notable features is SpectraBand, which provides an unparalleled tuning range of 169 - 1525 MHz. This wide frequency range allows users to easily locate open spectrum, even in densely populated UHF TV bands, ensuring clear and uninterrupted audio capture.

With the GainForward feature, the A20-Nexus Go receiver simplifies on-set workflows by allowing audio level adjustments directly on the receiver, rather than on the transmitter. This means no more interruptions to the action for gain tweaking, providing a smoother and more efficient production process.

The receiver's endurance and control are further enhanced by Sound Devices' proprietary NexLink protocol. NexLink offers robust long-range remote control of transmitters, ensuring reliable communication even amidst potential 2.4 GHz interference on set. Additionally, the integrated RTSA (Real Time Spectrum Analyzer) in the A20-Nexus Go transmitter allows for real-time visual monitoring of the RF environment, ensuring optimal frequency selection without disrupting the audio or production.

To streamline frequency coordination, the A20-Nexus Go receiver features the AutoAssign function. This intelligent tool automatically scans the current tuning band for the cleanest frequencies and assigns them to the receiver's channels. These frequencies are then automatically synchronized with transmitters connected via NexLink, all with the press of a single button, saving precious time during setup.

In summary, the A20-Nexus Go 4-Channel Digital True Diversity Wireless Receiver is an essential tool for audio professionals seeking an advanced, reliable, and flexible wireless audio solution. With its innovative features and sophisticated design, it stands out as a top choice for those looking to enhance their audio capture capabilities in any professional setting.
