  • 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. 169 MHz – 1525 MHz tuning range via SpectraBand Technology.
  • NexLink: an advanced long-distance modulation that allows for remote control of wireless transmitters from the receiver.
  • 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-TX and A20-Mini transmitters 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 or A20-TX transmitters. 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.
