Introduction
General Description
Thank you very much for your purchase of the MUTEC REF 10,
an audiophile 10 MHz reference master clock generator.
The REF 10 is an audiophile reference master clock generating
10 MHz signals with industry-leading low phase noise (i.e. jit-
ter) to significantly improve digital playback systems. As the
conductor of your digital audio orchestra at home, the REF
10 will inspire you with unheard-of clarity, graceful dynamics,
and pure music. It is also the most flexible, most compatible
10 MHz clock on the market allowing you to spend less time
worrying about integration and leaving you with more hours
to enjoy blissful playback.
In contrast to so-called “atomic clocks”, clocks based on a
rubidium or cesium normal, the REF 10 is engineered around
MUTEC's handcrafted, oven-controlled oscillator (OCXO)
made in Germany, featuring significantly higher clock stabi-
lity in the time domain relevant for audiophile digital audio
performance. Newly developed ultra-low noise clock distribu-
tion and amplification circuits based on sub-1 Hz optimized,
lowest noise voltage sources transfer the reference signal to
the REF 10's eight outputs with virtually no losses.
As a result and unlike any other currently available reference
generator the REF 10 fulfills both of the critical requirements
for an extraordinary audiophile reference master clock:
•
Lowest possible phase noise for unmatched audio
•
Highest clock precision for most accurate synchronization
Due to its revolutionary clock reference and its unrivaled flexi-
bility the REF 10 can enhance the audio quality of compatible
D/A converters (DACs), music servers, and re-clockers to the
highest possible level. Unlock a more dynamic, more trans-
parent sound stage with exceptional spatiality and level of
detail, free from any digital blur. As the quasi conductor of
your digital audio orchestra at home, we are sure the REF 10
will inspire you with unheard-of clarity, graceful dynamics,
and pure music!

Matching MUTEC Products
•
MC-3+ Smart Clock
The MC-3+ Smart Clock is an audio re-clocker and master
clock that can enhance digital audio devices in two ways:
by providing low-jitter clock signal for external synchro-
nization and by aggressively re-clocking using MUTEC’s
REVIVE technology.
•
MC-3+ Smart Clock USB
As the successor of the MC-3+ Smart Clock , the MC-
3+USB offers significantly improved audio performance
and additionally acts as an isolating USB interface for
audio computers and music servers.
•
iClock & iClock dp
iClock and iClock dp are both synchronizable, highest
precision clock synthesizers with extremely low jitter
for applications in audio/video production studios and
broadcast.
