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.
Ultrahigh Precision OCXO
The core of the unit features a custom OCXO (Oven Controlled Crystal Oscillator) newly developed by ESOTERIC that is comprised of an oven that maintains a constant internal temperature, a crystal oscillator, and an oscillating circuit. This OCXO was designed for high audio quality based on the wisdom of the Grandioso series to provide an excellent center frequency precision (±0.01 ppm Typ), and reduces phase noise by approximately 3 dB* compared to previous model.
