TransAudio Group, the U.S. distributor of the world’s finest high-end professional audio recording equipment, is pleased to announce the new MUTEC REF10 SE120 Audiophile 10 MHz reference master clock. Its forerunner, the MUTEC REF10, was already widely regarded as the most stable reference clock available and offers two 50 Ohm and six 75 Ohm galvanically-isolated BNC outputs. The REF10 SE120 incorporates a new, state-of-the-art oven-controlled quartz oscillator that brings conservative jitter measurements to below 15 fs (15 x 10^-15 seconds!) and thus substantially improves perceived audio precision, transparency, imaging, and dynamics. Only a small number of hand-selected oscillators can meet the demanding specs so the REF10 SE120 will be available in limited quantities.

“MUTEC makes the world’s best clocks, and they got there by continually asking ‘how can we do better?’” explained Brad Lunde, president of TransAudio Group. “The MUTEC REF10 was already phenomenal. The REF10 SE120 takes it to an incredible new level with oscillator technologies that leverage the very best German science and engineering. It’s geeky stuff, but the results translate into a more emotional, immersive audio experience!”

Each of the MUTEC REF10 SE120’s eight outputs are independently engageable. At the time it ships, frequency stability is below 0.01 ppm at any temperature humans would find tolerable (-4 to 158 degrees Fahrenheit) and will remain below 0.2 ppm after decades of operation. Phase noise remains below -120 dBc/Hz at 1 Hz and below -167 dBc/Hz at 1000 Hz. An isolated, dual-linear power supply powers the 9.5 lb. unit, with optional rack ears for studio installation.

MAP is $6,499 and they are now available to order.
