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 12 and 16 with additional software 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 wireless audio transmission.
Network away
You’ve got options. Use the built-in web server with any computer, tablet, or phone to control the A20-Nexus wherever your ethernet cable can take you. Power the receiver from a distance using Power-over-Ethernet (PoE) and remotely deliver audio via Dante. The possibilities are boundless.
Real Time Spectrum Analysis
The days of waiting for a scan to complete are over. Instantly visualize the RF spectrum around you in real time and coordinate frequencies all while monitoring 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.
The A20-Nexus joins the growing lineup of Sound Devices Astral™ wireless technology. 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.
- 8-channel ultra-high-performance, true-diversity receivers in a ½ rack size (8.0” x 6.6” x 1.6”).
- Expandable to 12 or 16 channels via additional software license (coming soon). Each +4 channel software expansion is priced at $2500 USD.
- 470 MHz – 1525 MHz tuning range via SpectraBand Technology.
- NexLink: an advanced long-distance modulation that reaches even farther than the A20-Mini’s long-range wireless audio transmission and functions separately or alongside A20-Remote.
- Dante audio-over-IP of RF receiver audio.
- Flexible powering: via PoE+, DC input, 8-Series, or AC mains (with optional adapter).
- Web App control from browser on any computer, smartphone or tablet.
- Full remote operation capability: Power via PoE, audio via Dante, control via Web App.
- Dual DB-25 connectors for 16 channels of mic, line, or AES outputs
- Convert 16 channels of Dante to analog and/or AES on DB25 connectors, for sending IFB, voice-of-god, and more from mixer to set.
- Wide, 6.2” color OLED array with touch for control and monitoring.
- Integrated Real Time Spectrum Analyzer (RTSA) and scanning for intuitive frequency coordination.
- Optical Fiber Network option via SFP slot. SFP accepts a wide variety of modular network transceivers. A20-QuickDock allows docking and undocking in seconds from 8-Series mixer-recorders with no tools.
- Modular design: RF section (A20-Nexus) can be disconnected and remoted from 8-Series, as opposed to less-flexible integrated RF/Mixer/Recorder solutions.
- All NexLink control is handled by A20-Nexus and/or its Web App instead of the 8-Series for maximum flexibility.
- Full remote power-down: A20-Minis can be fully powered down via NexLink for excellent battery life. This alleviates the need for remote auto-RF-Power adjustment schemes. User is in full control of RF power settings.
- Supports GainForward Architecture: No gain setting on the A20-Mini transmitter. Adjust gain at the receiver or mixer.
- 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
