Quick Start
This Quick Start guide assumes that the A20-Nexus is being used as a standalone receiver.
1.
Connect a 10-18V DC power source to either or both TA4-M DC inputs. Alternatively, connect PoE+ to Ethernet port 1.
2.
Connect suitable passive, bias-powered, or smart antennas to either the front or rear BNC A and B antenna ports.
3.
If using NexLink to control and monitor A20-Mini transmitters, connect 2.4 GHz antennas to both rear panel 2.4 GHz SMA
ports.
4.
Connect required rear panel audio outputs (Analog, AES, and/or Dante) from Nexus to external devices.
5.
Connect headphones to the front panel 3.5 mm headphone output.
6.
Power Up.
Press the front panel triangle button to power up. Press and hold to power down. When powered up for the
very first time, receiver channels 1-8 are displayed. This view is called the 8RX View. All RX channels will be Off.

that the A20-Remote app they are paired to is also set to the same country.
