Description
Bridge Your Digital Audio: M-Audio Midiman C02 Coaxial Optical
The M-Audio CO2 is a compact, rugged utility tool designed for the specific challenge of interconnecting digital audio formats. If you have ever encountered a situation where your surround sound receiver features only optical (TOSlink) inputs while your audio components provide coaxial (RCA) outputs—or vice-versa—the CO2 is the professional-grade solution you need.
This versatile converter features a “2-in, 2-out” design, allowing it to operate as a full-duplex, bi-directional converter. It can simultaneously convert coaxial to optical and optical to coaxial, making it an essential component for complex home studio racks or home theater setups. With its transformer-isolated RCA jacks, the CO2 also prevents ground loops, ensuring your signal remains clean, pristine, and free of unwanted electrical noise.
Professional Digital Audio Features
-
Bi-Directional Conversion: Supports simultaneous conversion between S/PDIF Coaxial and Optical (TOSlink) signals.
-
Repeater Functionality: Can be used as a signal repeater to extend TOSlink cable runs beyond standard limits (10+ feet).
-
Ground Loop Protection: Transformer-isolated RCA jacks ensure a clean signal by preventing ground loops in your system.
-
Rugged, Compact Design: Built to last in a portable, ultra-compact chassis that fits easily into any rack or desktop setup.
-
High-Resolution Support: Maintains signal integrity for PCM audio up to 24-bit/96kHz.
💡 Pro-Tip: The CO2’s mode switch is intentionally recessed to prevent accidental changes during use. Use a pen or a small precision tool to toggle between Optical-to-Coax, Coax-to-Optical, or Bi-Directional modes as needed.
