About Sound Devices A20-Nexus

From the cutting-edge world of wireless technology comes the A20-Nexus 8-Channel Digital True Diversity Wireless Receiver, a compact half-rack unit designed to redefine your audio experience. This state-of-the-art receiver is engineered for expansion, allowing you to upgrade from 8 channels to 12 or even 16 channels with additional software, ensuring your setup can grow alongside your needs.

At the heart of the A20-Nexus is its groundbreaking SpectraBand technology, an industry-first that offers an impressive tuning range of 470 to 1525 MHz. This wide spectrum capability provides unmatched flexibility, enabling you to locate open frequencies away from the crowded UHF TV band, ensuring clear and uninterrupted audio transmission.

The A20-Nexus is equipped with the advanced NexLink protocol, facilitating long-distance control of A20-Mini and A20-TX transmitters through its built-in long-range remote control link. This feature is complemented by a built-in web server, allowing seamless control from any computer, tablet, or smartphone connected via ethernet, enhancing your operational convenience.

Power-over-Ethernet (PoE) support further extends the receiver's versatility, enabling remote powering and audio delivery through Dante, thus broadening your audio distribution options. The real-time spectrum analysis feature is a game-changer, providing instant visualization of the RF spectrum, allowing you to coordinate frequencies and monitor audio without delay.

The A20-Nexus also introduces the innovative GainForward Architecture, a feature that allows direct control over gain, low-cut, and limiter settings on your A20-Nexus or mixer-recorder. This eliminates the need for transmitter-side adjustments, streamlining your workflow and enhancing audio precision.

Designed for adaptability, the A20-Nexus's compact half-rack size ensures it fits seamlessly into any setup, whether in a rack, a bag, or docked to an 8-Series mixer recorder for a cableless configuration. The AutoAssign function simplifies frequency management by automatically scanning for clean frequencies and assigning them to multiple channels, which are then communicated to transmitters via the NexLink protocol.

Experience the future of wireless audio with the A20-Nexus 8-Channel Digital True Diversity Wireless Receiver, a device that not only meets but exceeds the demands of modern audio professionals, revolutionizing your wireless experience with its unparalleled features and flexibility.
