AES3 to anything. Anything to AES3. Including Sample Rate Conversion!
The FLX-AES3/SRC is a compact AES3-to-anything converter with built-in Sample Rate Converters. It features 16x16 channels of AES3 , which can be converted to any protocol installed into the AUX slot. Additionally, all AES3 inputs can be routed through individual built-in SRCs to match a common clock. 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-mkII or another Flexiverter.
Overview
Features
- 16x16 channels of AES/EBU, fully transformer isolated
- Inputs can optionally be routed over 8 individual SRCs, to convert streams with different clocks to house clock
- 8 different input clock domains converted to the main clock domain, with top-notch SRCs (>120dB THD+N, >134dB DNR)
- Can work as AES3/AES3 Sample Rate Converter (convert individually clocked inputs to common clock output)
- AUX port accepting any of the AUX Cards as conversion source/destination
- Supports arbitrary sample rates in the range from 44.1...192kHz
- DB25 connector pinout (Tascam or Yamaha) selectable individually for each connector via internal jumpers
- FlexLink port for lowest latency, bi-directional transfer of 192 channels audio, clock and power
- Web-based Remote control (no software required), or UART command line
- Triple-redundant power supply
Additional features when connected to the MVR-mkII
- True channel-wise routing of all available channels (built-in plus AUX card)
