Esoteric G-02X Master Clock Generator


View All Esoteric



The G-02X uses a high precision oven-controlled crystal oscillator (OCXO) that provides optimal stability as an audio clock. Featuring 4 x 10MHz outputs and 4 variable frequency outputs.

Master clock generator

 A 'clock' is a pulse signal that is used as a reference signal for all digital circuits. Every piece of digital gear has an on-board clock oscillator, and a high-quality clock is vital for precise, jitter-free signal processing. The G-02X is an external clock device designed to supply ultrahigh precision clock to digital devices (such as a transport, DAC, SACD player, or network audio player) equipped with dedicated input terminals. The G-02X can supply clock signals with a significantly higher degree of purity and stability than clocks generated by connected devices themselves, and thereby significantly improves the sound quality.
