The Aune S1c is a high-performance external clock with an optimized audio architecture, including an OCXO oscillator and an FS-1 frequency synthesizer designed by Titans Audio Lab, with efficient power supply and signal isolation. It provides three 10M and three WCK independent outputs and can be powered by DC or AC. The 10M outputs take advantage of Adaptive-Z technology and are therefore compatible with devices with 50Ω, 75Ω and even 10k input impedance. The WCK outputs are perfectly adapted to the 75Ω standard.
