RF

  • Tuning
    • 169 to 1525 MHz (1356 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 an A20 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

Powering

  • Sources
    • TA4 DC Input
    • 8-Series (through unit-to-unit connector when docked)
    • AC mains adapter (sold separately)
  • Levels
    • DC input, 10 to 18V in, 2A minimum at 10 VDC
    • 10W 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 transmitters, and USB hubs
    • DC Outs: max 500 mA between both outputs.

Environmental

  • Operating Temperature Range
