A20-Nexus Sound Devices

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 169 – 1525 MHz in a single unit – an industry first! Experience ultimate flexibility as you find open spectrum away from the crowded UHF TV band.

NexLink
With NexLink’s advanced long distance protocol, you can control your A20-Mini and A20-TX transmitters using the built-in long range remote control link. 

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 and A20-TX transmitters’ GainForward Architecture, easily set the 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.

AutoAssign
Assigning frequencies to wireless transmitters used to take forever. Not with the A20-Nexus true diversity wireless receiver’s AutoAssign function. It automatically scans the current tuning band for clean frequencies and assigns them to multiple channels. The clean frequencies are then automatically pushed to transmitters linked to the NexLink protocol.

• 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 A20-Nexus 4-Channel Expansion License. Licenses are $2500 USD, or $250 USD for a 7-day rental, or $850 USD for a 30-day rental.
• 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.
• The AutoAssign function automatically scans the current tuning band for clean frequencies and assigns them to multiple channels. The clean frequencies are automatically pushed to NexLinked transmitters.
• 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
