AES/EBU and SPDIF Format Convertor



  • Conversion from SPDIF to AES/EBU
  • Conversion from AES/EBU to SPDIF
  • Automatic Sample-Rate Detection
  • Exclusive Sure-Lok™ Auto-Recovery Sentinel
  • Sample Rate/Valid Conversion LEDs
  • Full Operation up to 24 bit / 96 kHz
  • Transformer Isolated Inputs / Outputs

APPLICATION: The RDL-HR-UDC1 is the ideal choice in applications where digital audio signals must be converted between consumer and professional formats.

Four jacks are provided for the input: SPDIF Phono, SPDIF or AES-3ID BNC, SPDIF Optical and XLR AES/EBU. Any one of these input jacks may be used. Four output jacks are provided: XLR AES/EBU, SPDIF Phono, SPDIF BNC, and SPDIF Optical. The electrical inputs and outputs are all transformer isolated. The coaxial jacks (phono and BNC) are connected to each other, therefore only one of these jacks may be connected at a time. LED indicators are provided to show the direction of conversion: SPDIF TO AES/EBU or AES/EBU TO SPDIF.

Sure-Lok auto-recovery circuitry included in the RDL-HR-UDC1 monitors the most frequent causes of latch-up and reinitiates digital signal lock, bringing a new higher level of stability to digital audio signal format conversion under the variety of conditions encountered in professional environments.
