The high precision G-01X master clock genenartor adopts new technologies such as "Wide Range Clock Buffer Amplifiers", "Adaptive Zero Ground" circuits, and a high precision rubidium oscillator to attain the very best in muscial expression from your digital audio system.
An extremely high precision American-made rubidium oscillator with a frequency precision of ±0.05 ppb or ±0.00005 ppm is used as the core of this extraordinarily accurate timing device. This oscillator module has been manufactured to ESOTERIC's demanding specifications with sound quality and stability being given top priority. The sound quality one would expect from a high end model has been achieved.
The G-01X has the "Adaptive Zero Ground" circuitry inherited from the Grandioso G1 between the internal rubidium unit and the buffer amplifiers. The "Adaptive Zero Ground" mode actively drives the ground signal to 0 volts and greatly reduces noise (random jitter) caused by variation in the ground voltage. The user can select between the adaptive mode and the normal mode, for different sound characteristics according to their listening preferences.
A 10 MHz or 1 pps reference signal can be input externally by connecting a device such as a GPS receiver to an external input terminal. The internal rubidium oscillator is synchronized with a higher center frequency precision clock received from a satellite, and this allows more stable rubidium oscillation than the crystal controlled oscillator built into the external GPS receiver, which makes the most of the advantages of a high precision GPS system.
