Astral ARX32
SKU: ARM-RF-SD-ASTRAL-ARX32
The Sound Devices Astral ARX32 is a 1RU digital wireless receiver for larger broadcast, theatre and live production systems. HexVersity reception, flexible audio routing and network control help bring multiple wireless channels together in one rack space.
Included channel configuration
This listing is for the base 16-channel receiver. Expansion to 24 or 32 channels requires additional eight-channel software licences, supplied separately. Ask ARM for a quote for your required channel count.
Key features
- HexVersity reception with two to six antennas.
- SpectraBand tuning from 169–1525 MHz, with frequencies dependent on region.
- NexLink remote control of compatible Astral transmitters.
- Integrated real-time spectrum analysis and AutoAssign frequency deployment.
- Dante, MADI, AES and analogue outputs.
- RF Mirror Mode for redundant operation.
- Browser control through the built-in Web App.
