REF10 SE120 Master Clock

The REF10 SE120 is a special version of the successful audiophile reference clock generator REF10 that we have further enhanced in terms of signal performance. The exceptional quality of the original REF10 has been confirmed many times since its launch in 2017 – in numerous reviews from specialized magazines and through enthusiastic user feedback. A clock generator from MUTEC significantly increases the quality of digital music playback, even and especially with demanding high‑end systems and studio installations. Because it provides the foundation for perfect signal processing in a digital audio chain: the extremely low‑noise reference clock.

The "tuning" variant REF10 SE120 outperforms the original model REF10 in this regard considerably. A clearly measurable advantage is the result of a special feature of the REF10 SE120: its much more elaborately manufactured and selected oven‑controlled quartz oscillator (OCXO). This oscillator is selected according to the strictest standards in test procedures lasting many hours with the help of exceptionally precise and expensive measuring technology. The use of such an outstanding oscillator is responsible for the fact that the REF10 SE120 from MUTEC currently delivers - to our knowledge - the lowest phase noise, respectively jitter values in the industry. This outstanding technical performance has a noticeable impact on the sonic result. Precision, transparency, spatiality and dynamics of the musical presentation reach an unprecedented level and will inspire you!

Like the proven REF10, the optimized REF10 SE120 is extremely flexible. Because of its versatile connectivity this MUTEC clock generator can be successfully integrated in a wide variety of configurations while maintaining an easy way of operation. If you want to maximize the sound potential of your compatible DA converter, music server or audio re‑clocker in every respect, you need the REF10 SE120 from MUTEC!
