The A20-SuperNexus is a gamechanger. A 16-channel receiver with HexVersity (2- to 6-antenna diversity), expandable to 32 channels via software licenses - all in just a 1U 19" rack, A20-SuperNexus keeps your kit small and saves space in your rack.

Take it on tour without worrying about tuning bands - it boasts a 169-1525MHz tuning range for worldwide operation. A20-SuperNexus gives you peace of mind with its RF Mirror Mode for full redundant operation.

MAIN FEATURES:

16 channels all with HexVersityr (2-, 3-, 4-, 5-, or 6-antenna diversity) in 1U rack space
expandable to 32 channels (all with HexVersity) in the same rack space via Software Licenses
169 1525 MHz tuning range for full global coverage
RF Mirror Mode for full redundant operation

ADDITIONAL FEATURES:

Native Dante, MADI, AES, and Analog outputs
spectraBand with 3 Tuning Bands for a total of ~72 MHz of operating bandwidth for transmitters
optional A20-Opto expansion box to add Optocore audio I/O and full redundant power supplies
simple 1-minute operation to change countries for entire system
built-in long-range NexLinkr remote control of all transmitters
integrated Real Time Spectrum Analyzer (RTSA) and scanner for intuitive frequency coordination
autoAssign: automatic deployment of multiple clean frequencies in seconds
built-in 6-to-2 RF combiner for multizone events
6 network ports (2 x RJ45, 4 x SFP) configurable for Dante, Dante Redundancy, and Control
