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-01X master clock generator is an external clock
device designed to supply atomic precision clock to digital devices
(such as a transport, D/A converter, Super Audio CD player, or network
audio player) equipped with dedicated input terminals. The G-01X 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 Rubidium Oscillator
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.
“Wide Range Clock Buffer Amplifier”
The “Wide Range Clock Buffer Amplifiers” developed for the Grandioso G1
flagship model are adopted to provide an even wider frequency range than
ever before. These discrete circuits using high-speed transistors with
excellent high frequency performance are separated for each output
terminal to greatly contribute to major improvements in sound quality by
providing an accurate and stable timing signal to audio devices.
“Adaptive Zero Ground” Mode
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.
Substantial Power Supply
A newly-designed power supply is adopted to maximize the performance of
the new “Wide Range Clock Buffer Amplifiers”, with a separate power
supply regulator assigned to each of the independent buffer amplifiers.
The amplifier and power supply are divided into blocks to ensure drive
that is both clean and powerful. A large toroidal transformer is used as
the main transformer and a dedicated El core transformer is used for
digital 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, which assists the accuracy of the
clock’s signal generation.
Eight Outputs
The G-01X 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 × 2 and B × 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.
External 10 MHz/1 pps Input
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.
Gold Plated BNC Terminals
The unit adopts milled brass BNC terminals to achieve a secure
connection. These allow high-end cables to be easily connected and
minimize loss of transmission to the utmost limit.
Preheat Function
The unit features a preheat mode, which shuts down the unit but
continues to supply power to the internal rubidium oscillator. Keeping
the rubidium warm reduces waiting time after the power is turned ON and
enables the unit to provide its full performance immediately.
