INTRODUCTION

Thank you very much for purchasing the MC-3+ Smart Clock, Synchronizable
Digital Audio Master Clock Generator, from MUTEC !

General Description

The new MUTEC MC-3+ Smart Clock is especially designed to improve the
acoustical quality of digital audio devices in two ways: At first by clocking
external devices with ultra-low jitter Word Clock signals and secondly by
aggressively re-clocking incoming digital audio signals. Therefore, we have
developed a totally new clocking technology, which we are calling the
»MUTEC 1G-Clock«. That means in practice, we are running – for the first
time in the audio industry – an audio clock synthesis process with a basis
clock rate in the gigahertz area! Together with new ultra-low-noise power
supplies and new PCB design rules aligned to high-speed communication
technologies, the MUTEC 1G-Clock brings jitter and electrical noise down
to unique low levels, which leads to unprecedented transparency in your
audio recordings.

Also working as a clock distributor and unlike other products, the MC-3+
effectively regenerates incoming clock signals to higher purity as the signal
source. Thus, the MC-3+ enables to improve already existing clock systems
and helps to raise the standard of sound reproduction in every studio
environment.

Additionally, the MC-3+ Smart Clock locks to so-called atomic clocks or
GPS receivers to raise its timing accuracy to the highest possible level. For
use during live events or in mobile trucks, the MC-3+ features an anytime
fail-safe clock generation in every operation mode. Entering the hold-over
mode and re-synchronization of returning clock references is carried out so
smoothly that live recordings surely will not affected.

The new MUTEC MC-3+ Smart Clock and its unique 1G-Clock add with the
most aggressive jitter reduction a significant improvement in sound to any
studio set-up, while ensuring flawless synchronization of connected devices
at any time!
