MC1.1+ Digital Audio Format Converter


The MC-1.1+ is a high performance, bi-directional format converter for AES, AESid, and S/P-DIF.




  • AES/EBU, AES/EBUid, and S/P-DIF optical/coaxial interfaces in one box
  • Uni- and bi-directional format conversions, 16-24bit/32-192kHz, between AES3/AES3id and S/P-DIF
  • Signal improvement and stabilization by low-jitter PLLs
  • Converts to all output formats simultaneously while allowing the original signal to pass through
  • Works as active signal splitter for AES3/AES3id and S/P-DIF
  • Every interface standard offers two separately buffered outputs
  • Detects NONE-PCM and DTS bitstreams
  • SCMS processing, SCMS copy bit generation of original and 1st generation incl. SCMS pass-thru functionality
  • S/P-DIF signal analyzing with automatic detection of SCMS original + 1st generation status; none-PCM and DTS detection
  • User settings maintained upon power off
  • Straightforward user interface
  • Rack-space-saving 9.5“ housing
  • Built-in, international power supply
  • Made in Berlin, Germany
