Audison Accessories C2O Coax to Optical Converter

C2O Accessories | Coax to Optical Converter | Up to 24-bit / 192 kHz Digital Audio

The Audison C2O converter is a high-performance Coax to Optical (S/PDIF) digital audio converter designed to deliver uncompromising sound quality and flexibility in modern vehicle audio systems. Engineered for enthusiasts and professionals alike, the C2O supports audio resolutions up to 24-bit / 192 kHz, ensuring audiophile-grade signal transmission for advanced car audio setups.

The device features a coaxial digital input with an isolation transformer, effectively reducing EMI (electromagnetic interference) and ensuring clean, balanced signal transfer in electrically noisy automotive environments. It also includes an AUX-IN analog input with adjustable gain (0.1V–2V), paired with a high-quality A/D converter operating at 24-bit / 48 kHz, delivering exceptional clarity and signal integrity from analog sources.

Smart input management prioritizes the AUX-IN by default, automatically switching to the coaxial digital input after 6 seconds of inactivity, with optional settings to extend delay to 9 or 12 seconds. This makes the C2O especially convenient for in-car use, seamlessly switching sources without user intervention.

Compact, rugged, and easy to install discreetly within the dashboard or hidden compartments, the Audison C2O is compatible with a wide range of amplifiers and DSPs. Whether you’re integrating legacy equipment or optimizing a high-resolution signal path, the C2O ensures reliable, noise-free audio transmission with complete control and unmatched sound precision.
