MC-4 Digital Multichannel Format & 16ch Sampling Rate Converter

 

The MC-4 is a high performance digital multichannel audio format and 16 channel sampling rate converter for ADAT™, AES3 and S/P-DIF.

 

 

Features:

  • ADAT™, AES/EBU and S/P-DIF interfaces in a single unit
  • Format and sample rate conversions up to 192.0 kHz
  • SMUX2 and SMUX4 support for ADAT™conversions
  • Signal improvement through audiophile-optimized PLL synthesizers
  • Extremely flexible synchronization options
  • Separate AES11 reference clock input for e.g. broadcast use
  • Converts standalone and bidirectionally with different sampling rates: X-SRC
  • 16 channel sampling rate conversion engine (SRC) for bidirectional conversions
  • Continuous signal supply in absence of the reference audio or clock signal
  • Runs standalone in all SRC operation modes without needing an external master clock reference
  • AES11, Grade 1, internal reference clock (0.5 ppm)
  • Word Clock output usable as master clock reference
  • Straightforward configuration
  • User settings stored upon power off
  • Compact format
  • Built-in international power supply
  • Made in Berlin, Germany
