MUTEC REF10 Silver – 10 MHz Reference Master Clock for Audiophiles

The Mutec REF10 Silver is a high-end 10 MHz reference master clock, engineered for the most discerning audio professionals and enthusiasts. Built around a handcrafted, oven-controlled OCXO oscillator, it delivers outstanding phase noise suppression and ultra-low jitter performance. It enhances sound quality across digital systems including DACs, music servers, re-clockers, and master clocks. The Silver version features a refined anodized aluminum front panel, combining elegant aesthetics with precise German engineering.

Key Features

• Handcrafted OCXO oscillator with ultra-low phase noise
• Eight galvanically isolated BNC outputs (2 x 50 Ω, 6 x 75 Ω)
• High slew-rate square wave 10 MHz signal
• Multi-stage linear power supply with isolated OCXO supply
• Sub-Hz optimized, ultra-low noise voltage regulation
• Rack-mountable (2U) with optional brackets

Digital precision that elevates every note

The REF10 Silver achieves exceptional short-term timing stability—essential for premium digital audio. Unlike atomic clocks that emphasize long-term stability, the REF10 is optimized for minimal phase noise and jitter (~22 fs @ 1–100 Hz), delivering clearer imaging, more realism, and sonic purity free from digital haze.

Applications

• High-end DACs and audio converters
• Music streamers and re-clockers
• Digital master clocks and audio synchronizers
• Mastering studios and reference-grade audio setups
