A Versatile Multichannel Receiver Ready for the Bag, Cart, or Rack

Busy audio professionals looking for a multichannel wireless microphone receiver that can quickly and easily move between bag, cart, and rack applications will find a lot to appreciate in the A20-Nexus from Sound Devices. This 1/2-rack, 8-channel solution can be expanded to accommodate up to 16 channels and uses SpectraBand technology to provide mission-critical reliability across an ultrawide 470 to 1524 MHz tuning range—allowing it work anywhere on Earth. With a host of flexible powering options, Dante networking, and seamless integration with the Scorpio and 8-Series mixer/recorders, the A20-Nexus is packed with features to speed up your workflow, whether you're working in the field, on a production set, or at a live-performance venue.

SpectraBand + Real Time Spectral Analysis

• SpectraBand technology delivers a tuning range of 470 to 1525 MHz in a single unit. 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 to 1525 MHz range, keeping your kit small and tidy and allowing you to work anywhere.
• In addition, with Real Time Spectral 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 Transmitter Control

• Use the GainForward architecture on the A20-Mini transmitters (available separately) to 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.

NexLink Remote Control & Dante Networking

• 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.
• 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.

Features

• 8-channel ultrahigh-performance, true-diversity receiver in a 1/2-rack size (8.0 x 6.6 x 1.6”).
• Expandable to 12 or 16 channels via additional plug-in.
• 470 to 1525 MHz tuning range via SpectraBand Technology.
• NexLink: 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, or 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 touchscreen 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 (available separately) allows docking and undocking in seconds from 8-Series mixer-recorders with no tools required.
• Modular design allows A20-Nexus to 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 extremely long transmission distances.
• Excellent audio quality, full 10 Hz to 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.
