MUTEC MC3+ USB Interface, Master Clock and Audio-Re-Clocker
Frequently Bought Together
Product Overview & Specifications
The MUTEC MC3+ USB is a digital audio master clock, re-clocker, and USB interface designed for audiophile home setups and professional studio environments. Combining MUTEC's proprietary 1G-Clock technology with next-generation REVIVE re-clocking algorithms, it eliminates jitter and noise interference to deliver enhanced soundstage width, precise imaging, and increased musical transparency across all digital audio streams.
Featuring a galvanically isolated USB interface (up to 2500 VRMS) powered independently from the main board, the MC3+ USB effectively isolates digital audio signals from computer-induced electromagnetic noise. It converts incoming PCM and DSD/DoP streams (up to DSD256) into PCM audio and outputs them simultaneously across five digital audio formats. Additionally, it functions as a master clock generator supporting Word Clock rates up to 1,536.0 kHz and can lock to external 1–10 MHz atomic or GPS reference clocks.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- Proprietary 1G-Clock & REVIVE Re-Clocking: Employs ultra-high-speed Direct Digital Synthesis (DDS) processes to eliminate jitter and recombine audio data with a newly generated, ultra-low-noise clock signal.
- Galvanically Isolated USB Interface: Dedicated USB board with independent power supply and galvanic isolation up to 2500 VRMS / 4242 VPK to suppress computer-generated RF/EMI interference.
- Real-Time DSD/DoP to PCM Conversion: Converts DSD64–256 and DoP streams in real time to PCM audio at selectable output clock rates (44.1 kHz, 88.2 kHz, or 176.4 kHz).
- Master Clocking & External Reference Lock: Generates Word Clocks up to 1,536.0 kHz (including Super Clock FS1x512) and locks to MUTEC REF10, Rubidium (10 MHz), Cesium (5 MHz), or GPS clock sources.
- Simultaneous Multi-Format Signal Distribution: Transmits incoming audio streams simultaneously to five digital output formats (AES3, AES3id, S/P-DIF BNC, S/P-DIF RCA, and Optical Toslink).
- Bi-Directional Format Conversion: Converts between USB PCM/DSD audio, AES3, AES3id, S/P-DIF, AES11, and Word Clock formats for monitoring and recording flexibility.
- Roon Tested & Studio Ready: Fully tested and certified for seamless integration within Roon music playback systems and DAW studio environments.
