Sound Devices A20-Nexus Receiver

Sound Devices A20-Nexus Receiver

The Sound Devices A20-Nexus is a wideband half-rack receiver expandable from 8 channels up to 16 channels with software licenses. The A20-Nexus 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.

Upgrade to 12 or 16 receiver channels with the A20-Nexus 4-Channel Expansion License.

• 100% digital long-range modulation delivers the longest transmission distance of any system on the market.
• Excellent audio quality, full 10 Hz – 20 kHz audio bandwidth.
• RF SAW filters for excellent rejection of interference from nearby IFB or camera hop transmitters.
• BNC timecode input for auto timecode sync of transmitters over NexLink

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.

AutoAssign

The A20-Nexus v1.20 firmware adds the AutoAssign function, which automatically scans the current tuning band for clean frequencies, assigns them to multiple channels, and then automatically pushes them to NexLinked transmitters. Deploy multiple transmitters in seconds.

The updated A20-Nexus v1.20 firmware also adds the ability to globally power on and off all transmitters from the TX list. Firmware updates available from Sound Devices website.

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.¹ 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.
