MC-3+ USB Smart Clock

Introduced 2015$1,499 MSRP

The MC-3+ USB is Mutec's audiophile master clock, digital audio re-clocker, and asynchronous USB-to-AES/S-PDIF interface in a single 9.5-inch rack-space chassis. It uses Mutec's proprietary 1G-Clock and REVIVE re-clocking technology to bit-transparently clean up jitter from computer and streaming sources, and can lock to external references including the Mutec REF10, rubidium, cesium, and GPS clocks for further precision.
