Last updated

Patents: The A20-Nexus is protected by US patents US10678294B2, US20190166523A1, International patent WO2018022209A1, and several patents pending.

RF

  • Tuning
    • 470 to 1525 MHz (1055 MHz switching bandwidth)
    • 25 kHz steps
    • SpectraBand Technology for maximum rejection of out-of-band signals
    • Available frequencies depend on country of operation
  • Modulation
    • Proprietary, 100% digital RF modulation
    • Standard or Long Range, selectable per channel
  • Spurious Rejection
    • >100 dB typical
  • Cascade output
    • 50 ohm
    • 3.5 dB Insertion Loss from front BNC through rear BNC: It is recommended to use an external powered antenna to overcome the 3 dB splitting loss in the Nexus so that the receivers maintain excellent range.
    • Wideband power split, pre-LNA
  • RF Bias output
    • 12V, 200 mA each BNC
    • Smart antenna support, Wisycom-compatible

Audio

  • Latency
    • Standard modulation = 2 ms, analog or digital outputs
    • Long Range modulation = 3.9 ms, analog or digital outputs
  • Audio Frequency Response
    • 10 Hz–20 kHz, +/- 1 dB relative to 1 kHz
  • Dynamic Range
    • > 130 dB with A20-Mini as transmitter
  • Output Level
    • Line-level: +20 dBu for 0 dBFS
    • Mic-level: -20 dBu for 0 dBFS
  • Audio Output Sample Rate
    • 44.1, 48, or 96 kHz
  • Digital Audio Output
    • AES3 balanced connection, 110 ohm output impedance
  • Audio-Over-IP
    • Dante, 44.1 or 48 kHz sample rate

Network

  • Dante Audio-Over-IP
    • 16 input/output channels
  • Control
    • Web-based control and monitoring of all Nexus settings
  • Connections
    • 2x RJ45 ports: For Dante and/or Control. Port 1 supports powering from PoE+
    • 1x SFP: For Dante and/or Control. Compatible with Small Form-factor Pluggable (SFP) network transceivers

Powering

  • Sources
    • DC Input: dual, redundant (highest voltage takes precedence)
    • PoE+: 802.3at, 30W needed (standard 15W PoE 802.3af will not work)
    • 8-Series (through unit-to-unit connector when docked)
    • AC mains adapter (sold separately)
  • Levels
    • DC input, 10 to 18V in, 3A minimum at 6.5 VDC
    • 11 W idle, default configuration
    • Extra power passed through for USB power, active antenna power, and DC output power
    • USB-A: 5V, 500 mA output; supports keyboards, thumb drives, A20-Mini transmitters, and USB hubs

Environmental

  • Operating Temperature Range
    • -10 °C to +55 °C 
  • Dimensions (H x W x D)
    • 4.0 cm x 20.3 cm x 16.7 cm
    • (1.6 in x 8.0 in 6.6 in)
  • Weight
    • 1.27 kg (unpackaged)
    • 2.8 lbs (unpackaged)
