AES50 to anything. Anything to AES50.
The FLX-AES50 is a compact AES50-to-anything converter. It has two ports (96x96 channels@48k, 48x48 channels@96k) of AES50 built in, which can be converted to any protocol installed into the AUX slot. For larger systems, the built-in channels plus everything which the AUX card provides are also available on the FlexLink port, making it possible to use it as extension to the MVR-64 or another Flexiverter.
Overview
Features
- Two AES50 ports compatible to Behringer™ and MIDAS™ equipment
- AUX port accepting any of the AUX Cards as conversion source/destination
- Supports sample rates: 44.1/48/88.2/96kHz
- Forwarding of remote control (auxiliary) data between AES50 ports to split/merge audio while maintaining HA control
- 🅝AES50 Extender: AES50-over-fiber (with AUX-MADI-SFP card as DN9620 replacement) / AES50-over-Dante / AES50-over-anything with full headamp control.
This works by passing control data as normal audio on ch57-64 to a peer FLX-AES50, or multiverter, using the media of your choice. - FlexLink port for lowest latency, bi-directional transfer of 192 channels audio, clock and power
- Remote control via USB: web remote (no software required), or UART command line
- Triple-redundant power supply
Additional features when connected to the MVR-64
- True channel-wise routing of all available channels (built-in plus AUX card)
- Sample-rate conversion using the SRC-64
