MUTEC presents REF10 SE120: The Ultimate 10 MHz Reference Master Clock

MUTEC GmbH, manufacturer of audio equipment for studio professionals and audiophile consumers, proudly announces the release of the REF10 SE120.

The 10 MHz reference clock generator REF10 SE120 marks a new top position within its product category in terms of technology and audiophile performance. With a phase noise value of <‑120 dBc measured at 1 Hz distance from the carrier frequency of 10 MHz, the REF10 SE120 produces uniquely low jitter measured values of an average of <15 fs in the crucial measuring range between 1-100 Hz.

This outstanding technical quality has a clearly audible impact on the sonic performance of connected devices. Thanks to its extremely noise-free and exact clock the MUTEC REF10 SE120 improves and enhances the sound quality of compatible DACs, audio re‑clockers and music servers. Precision, transparency, spatiality and dynamics of the musical presentation now reach an unprecedented level.

The MUTEC REF10 SE120 is a special version of the worldwide successfully sold predecessor REF10 that was launched in 2017 and has now been further enhanced in terms of signal performance. The REF10 SE120 differs from the standard REF10 in regards to its much more elaborately manufactured and selected oven‑controlled crystal oscillator (OCXO).
“Without doubt, the REF10 was and is a milestone in the development of audiophile reference clock generators. During the development, we noticed that its sonic performance in particular is decisively influenced by the crystal oscillator used. As a result, our REF10 developer and our oscillator supplier came together to optimize the oscillator’s production so that a sufficient quantity of oscillators can be produced in the quality level required for the REF10 SE120. We are sure that with the REF10 SE120 we are offering our customers a product that fully meets the continuously increasing demands for audiophile improvement of audio components as well as delivering perfect clock synchronization in a commercial studio environment.“
Christian Peters, CEO MUTEC

Because of its versatile connectivity, the REF10 SE120 is extremely flexible while maintaining an easy way of operation. Eight simultaneous available clock outputs at both 50 Ω and 75 Ω impedance not only allow to use the REF10 SE120 in combination with MUTEC products having a 10 MHz input like MC3+/MC3+USB Smart Clocks and iClock/iClock dp, but also 10 MHz compatible components by third-party manufacturers.

  • 10 MHz reference master clock generator with ultimately low phase noise of ‑120 dBc at 1 Hz
  • Improves significantly compatible DACs, audio re‑clockers, music servers and master clocks
  • Engineered around an elaborately manufactured and selected OCXO made in Germany with outstanding low phase noise
  • Provides simultaneous reference outputs with 50 Ω and 75 Ω impedance for maximum compatibility with audio components by other manufacturers
  • Sub‑Hz optimized, lowest noise power supplies for every circuit section
  • Integrated highest quality international linear power supply
  • Highly efficient power line filtering
  • Easy operation

Due to the limited availability of meticulously tested and selected crystal oscillators, the MUTEC REF10 SE120 is available only in small batches and will be shipped with either a black or aluminum coloured front plate for the list price of € 5,498.00 (including VAT).
