Know before you buy
The REF10 SE120 acts as a master reference clock that synchronizes your digital audio components. By providing an ultra-low-noise signal, it reduces jitter and timing errors, which results in improved clarity, better spatial imaging, and more natural dynamics in your music playback.
Your equipment must have a dedicated word clock or reference clock input, typically a BNC connector. If your device supports an external 10 MHz reference clock, it is likely compatible with the REF10 SE120.
Yes. The unit features eight BNC outputs that provide both 50 Ω and 75 Ω impedance options. Because these outputs are galvanically isolated and individually switchable, you can safely connect multiple devices with varying requirements at the same time.
The Oven-Controlled Quartz Oscillator (OCXO) is kept at a constant, precise temperature to ensure extreme stability. This specific version is hand-selected for its industry-leading low phase noise, which is critical for maintaining the integrity of the digital signal.
Absolutely. The REF10 SE120 is built to professional standards and can be integrated into a rack setup using optional 2RU mounting brackets. Its robust power supply and high-precision output make it well-suited for demanding studio mastering and recording applications.
Like most high-precision OCXO-based clocks, the unit performs best after it has reached its optimal operating temperature. It is recommended to leave the unit powered on or allow it a brief warm-up period before critical listening or recording sessions to ensure maximum stability.
