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
