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.

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.

*Measured at an offset frequency of 100 Hz

“Wide Range Clock Buffer Amplifier”

The unit adopts the “Wide Range Clock Buffer Amplifiers” developed for the Grandioso G1. These discrete circuits utilize high-speed transistors with excellent performance at high frequencies and are separated for each output terminal to contribute to improved sound quality.

“Adaptive Zero Ground” Mode

The G-02X has the “Adaptive Zero Ground” circuitry inherited from the Grandioso G1 between the internal OCXO 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.

Substantial Power Supply

A newly-designed power supply is adopted to maximize the performance of the new “Wide Range Clock Buffer Amplifiers”, with the amplifier and power supply divided into blocks to ensure drive that is both clean and powerful. A toroidal transformer is used as the main transformer and a dedicated El core transformer is used for control. A series of multiple capacitors are used for the ripple filter circuit and Schottky barrier diodes are used for quick response to support fast digital processing.

Eight Outputs

The G-02X can supply a clock signal to a maximum of eight devices. Output can be switched ON and OFF for each terminal. The unit has four 10 MHz sine wave clock output terminals. The other four output terminals (A x 2 and B x 2) enable clock signals to be output at 100 kHz, 10 MHz (square wave), and the basic frequency of 44.1 kHz/48 kHz, up to a maximum frequency of 22.5792 MHz/24.576 MHz, and separate output frequencies can be set for each terminal.

Since 1987, Esoteric has pursued a path dedicated to being a superior high-end audio/video brand focused on introducing components of the best value by merging innovative, proprietary recording and replay technologies. In order to meet the desires of musical and visual connoisseurs who are seeking new levels of excitement, Esoteric’s mission has been to continue to develop and release new products that improve upon the "state of the art", from highly acclaimed pure audio/video source devices to Super Audio CD and DVD components. Esoteric applied its no-compromise philosophy with the same intense consideration to its flagship Grandioso series to produce the next dimension of sound and audio immersion. With the Grandioso series, Esoteric sought to eradicate ANY distortions and colorations by taking a fresh look at entrenched norms and design elements, and by scrutinizing every last design detail – no matter how minute. All of the design tweaks, too numerous to elaborate here, yield an exceptional sonic purity that sweeps away distractions and enables listeners to experience an unprecedented level of musical detail and stunning visual presentation. Overture, as a provider of the “ultimate” audio/video products, is a select dealer for Esoteric and its Grandioso line. If you are interested in purchasing Esoteric or Esoteric's Grandioso components and have an electronic component or more that you would like to trade-in, please fill out Overture’s Trade-In Form.
