Ultrahigh Precision OCXO

^{* when shipped new}

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

本產品的核心配有由ESOTERIC新開發的特製OCXO（恆溫控制晶體振盪器），其內部由恆溫控制器、晶體振盪器和振盪電路組成。此OCXO是本著Grandioso系列的設計理念，為了產生更高品質的音樂，且提供出色的中心頻率精度（±0.01 ppm Typ），與以前的型號相比，將相位噪聲降低約3 dB。
＊測試頻率為100Hz。

"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.

「寬頻時脈緩衝放大器」
採用為Grandioso G1開發的「寬頻時脈緩衝放大器」。這些分離式電路配有在高頻下具有優異性能的高速晶體管，並且針對每個輸出端子個別分離，有助於改善音質。

"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.

「零接地電壓調整」模式
G-02X在內部OCXO和緩衝放大器之間配備承襲自Grandioso G1的「零接地電壓調整」電路。「零接地電壓調整」模式讓接地輸出的基準電位維持在0V，能有效發揮防止因為接地電壓變動而產生噪訊（隨機性時基誤差）的效果。用戶可以根據個人聆聽偏好在調整模式/一般模式之間選擇不同的聲音特性。

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.

重量級電源供給
採用新設計的電源以最大幅度地提高新型「寬頻時脈緩衝放大器」的性能，放大器和電源分為多個區塊，以確保乾淨強大的驅動力。使用環形變壓器作為主變壓器，並且搭配專用EI核心變壓器來進行控制。另外，紋波濾波器電路採用同一系列多組電容，且使用蕭基二極體以達到快速響應並支援快速數位處理。

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.

八組輸出
G-02X可以為最多8組設備提供時脈信號。 每個端子的輸出可以個別開啟和關閉。本產品有四個10 MHz正弦波時脈輸出端子。其他四個輸出端子（A×2和B×2）能使時脈信號以100 kHz，10MHz（方波）輸出，基本頻率為44.1 kHz / 48kHz，最高頻率為22.5792 MHz /24.576 MHz，並且可以為每個端子設置單獨的輸出頻率。
