Sound Devices A20-Nexus

The future of wireless Meet the half-rack receiver with an entire rack's worth of features. The next-generation A20-Nexus is expandable from 8 channels up to 16 channels with software licenses and features forward-thinking technologies like SpectraBand, the powerful NexLink remote-control link, real time spectrum analysis, and more. With multiple options for audio outputs, powering, and remote control, the A20-Nexus can seamlessly adapt to your workflow, both now and in the future.

SpectraBand SpectraBand technology delivers a tuning range of 470 - 1525 MHz in a single unit - an industry first. Experience ultimate flexibility as you find open spectrum away from the crowded UHF TV band. The included A20-Monarch antennas can receive the entire 470-1525 MHz range, keeping your kit small and tidy. NexLink Control your A20-Mini transmitter using the built-in long range remote control link. NexLink's advanced long distance modulation reaches even farther than the A20-Mini's long-range audio transmission. Network away You've got options. Configure your A20-Nexus for Dante audio, use the built-in web server to control the receiver using the web browser on any computer, tablet, or phone, and even power the A20-Nexus remotely using Power-over-Ethernet (PoE). Real time spectrum analysis The days of waiting for a frequency scan to complete are over. Instantly visualize the fluctuating RF spectrum around you in real time - while running all channels of the audio. GainForward With the A20-Mini's GainForward Architecture, easily set the Mini's gain, low-cut, and limiter directly on your A20-Nexus or mixer-recorder. This immediate, local control of gain means never having to adjust the gain on the transmitter again. Go cableless Thanks to its half-rack size, the A20-Nexus is equally at home in a rack, in a bag, or docked to an 8-Series mixer recorder for a cableless kit. Long range The A20-Nexus and A20-Mini deliver the longest transmission distance of any system on the market. The state-of-the-art, 100% digital long-range modulation offers the same great audio quality (10 Hz - 20 kHz) as our Standard modulation scheme with a longer range for both line-of-sight and heavy multipath transmission. Shoot for the stars The A20-Nexus joins the growing lineup of Sound Devices Astral wireless products. With industry-leading features like SpectraBand, GainForward, NexLink, long range modulation, real time spectrum analysis, and more, the Astral Series pushes the bounds of wireless audio.
