G 02 Master clock generator equipped with high precision crystal oscillator Digital audio synchronized to one high precision master clock

Talk of the flawless sound produced by an audio system connected together with a high precision master clock has been circulating between high-end audiophiles in various forms.

The three dimensional effect of the sound stage gives the listener an actual feel of, say, the high ceiling of a concert hall in addition to the width and depth of original performance.

The listener is treated to a pure and focused image of the playback sound that gives a sense of reality as if one could reach out and touch it. When the final note of the musical instrument fades away, you almost perceive the gradual silence like the color of a dark veil. This is truly an ultimate achievement of audio playback that “conveys music” so close to the original sound it leaves an unforgettable impression on the listener.

With the aim of enhancing the true potential of ESOTERIC digital players, the clock generator “G Series” was redesigned as a new generation of devices with improved functionality, power and flexibility.

G 02 uses a high precision oven-controlled crystal oscillator (OCXO) that provides optimal stability as an audio clock.

This next generation clock generator can output a master clock of 10 MHz and 22.5792 MHz, perfect for controlling both audio and computer based devices.

Master clock generator

Every digital audio device operates with an internal circuit generating the clock signals, or heartbeat, required to operate that device.

This master generator is an extremely stable oscillator that supplies external clocks to digital devices (such as a transport, D/A convertor, Super Audio CD player) equipped with clock input terminals.

The G 02 master clock generator supplies clock signals with a higher degree of purity and stability than clocks generated internally by digital devices and vastly improves the sound quality.

By operating connected devices off the same highly stable master clock, timing errors called jitter are virtually eliminated greatly improving imaging and dimensionality while darkening the background.

Ultrahigh precision OCXO installed as the heart of the unit

The master clock generator uses a high precision crystal oscillator with a frequency precision of +/-0.01 ppm (parts per million) that is provided with custom tuning designed specifically for ESOTERIC.

G 02 has a built-in, oven-controlled crystal oscillator (OCXO) that generates stable oscillation under varying conditions. This is made possible by assembling a quartz crystal resonator and oscillation circuit in an oven that maintains the internal crystal and critical circuitry at a constant temperature.

G 02 achieves a very high frequency stability of +/-0.01 ppm under external temperature conditions of –20 °C to 70°C.

Newly designed discrete clock output driver circuit configuration

G 02 has adopted a newly designed discrete clock output driver circuit configuration. The discrete circuit uses a high-speed transistor that is optimal for generating digital waveforms for which ultrafast speed and a high degree of accuracy are required. Combined with a heavy-duty power supply, this discrete circuit contributes to major improvement of the sound quality by providing an accurate, stable timing signal to audio devices.

Heavy-duty power supply unit

The master clock generator is equipped with a heavy-duty power supply unit that fully supports its high level of performance.

A large R-core transformer featuring low loss magnetic flux leakage has been selected for the G-02.

A series of several capacitors and Schottky barrier diodes are used as a smoothing circuit for quick response to support fast digital processing, contributing to the generation of highly accurate clock signals.

For the display, an independent power transformer and a dedicated power supply circuit have been installed for each circuit block to minimize mutual interference between blocks.

Support for 10 MHz clock and 22.5792 MHz master clock outputs

G 02 can output a 10 MHz clock and 22.5792 and 24.576 MHz master clocks that are compatible with ESOTERIC’ s original “Direct Master Clock Link.”

Three separate A/B/C output systems

G 02 can output 100 kHz and 10 MHz in addition to clock signals of 1x, 2x, 4x, and 512x multiples (22.5792 MHz/24.576 MHz) of the base frequency (44.1 kHz or 48 kHz).

Moreover, in frequency expansion (EXP) mode, G-02 can output 8x, 16x, 32x, 64x, 128x, and 256x multiples of the clock frequency that enables it to supply clock signals to a wide range of devices, including professional equipment.

Each of these systems has two output ports supplying clock signals to a maximum of six devices.

The output frequency can be set individually for each of the six ports from A1 to C2.

If a single device is connected, all output ports other than the A1 port can be turned off.

External 10 MHz input port

G 02 is equipped with an input port that is capable of receiving a 10 MHz reference signal from an external device. This port can be connected to devices such as the Rubidium clock and GPS clock to further upgrade the system.

ESOTERIC’s original gold-plated BNC ports

g02rearG 02 uses ESOTERIC’ s original BNC ports that provide highly reliable contact. These durable and secure ports can handle even heavy and thick high-end cables.

Pride and Mission of "ESOTERIC" They are to reproduce the Original Master Sound,

"The joy of the highest levels of musical elation." Their corporate philosophy, as their foundation, has been unremittingly developing excellent audio products to reproduce the original sound performed by musicians in studio or concert hall. Since the inception of TEAC corporation in 1953, audio equipment has gone through various phases of development. From analogue vinyl records to analogue tapes, CDs to Super Audio CDs in digital era, then streaming audio in nowadays, there have been undergoing several transitions and technical innovations in auditory media. ESOTERIC COMPANY, which was born in the midst of such transition, shall pursue a unique path as a high-end audio brand, by deploying Super Audio CD players equipped with the VRDS mechanism that has sublimated its original mechatronics technology, as well as D/A converters, network players, amplifiers, and clock generators. Despite changing times and whirlwind markets, there remain musical connoisseurs who are seeking true excitement. As long as there are such people, we shall with great care, develop and actively release new products, that improve upon the "state of the art," within each business category that we pursue. We believe this is our mission
