Introduction
General Description
The MC-3+ Smart Clock USB is setting a new benchmark for clocking technology and the reproduction of digital audio by
uniquely combining an audiophile USB interface with an audio re-clocker in perfection!
The MC-3+USB's improvements to the sound quality of connected devices are two-fold: first as an ultra-low jitter clock with
industry-leading precision and noise performance, and secondly by aggressively re-clocking incoming digital audio signals.
MUTEC's proprietary 1G-Clock technology from the MC-3+ Smart Clock, appreciated by leading mastering engineers around
the world, has been significantly optimized. As a result, the MC-3+USB delivers an unmatched level of signal purity, precision,
and musicality.
As MUTEC's first clock generator with an high-performance, bi-directional two-channel USB interface the device provides
the best possible audio signal transfer between DAWs, digital sources and receivers, and the transmission and conversion of
DSD/DoP streams. The interface most notably acts as an USB isolator that is galvanically isolated from the rest of the signal
processing and therefore eliminates noise interferences from audio workstations. Using the cutting-edge components, lowest-
noise audio oscillators and power suppy, as well as high-speed, IT-tech isolators, the USB interface is close to immune towards
interferences from PCs, laptops or music servers. The MC-3+USB is capable of delivering in most cases a consistent, highest-
grade audio performance regardless of the quality of the USB source. Apart from that, future software updates can be realised
uncomplicated and fast via the USB interface.
Furthermore, the MC-3+USB is a flexible, bi-directional format converter, including the USB path of the interface. In addition
to ordinary PCM streams the interface is also capable of receiving native DSD and DoP streams and converting them to PCM
audio in real-time. The PCM audio can be sent to a total of five audio formats at different selectable clock rates simultaneously.
Thanks to innovative features like the signal conversion to five audio output formats, the DSD/DoP-to-PCM conversion, four
simultaneous Word Clock outputs, and the capability to lock to ultra-high-precision 1-10 MHz reference clocks, the MC-3+USB
is an extremely flexible, "must have" centerpiece within the listening room at home or for any digital studio!
