Features
Clock Generation by High-Precision Crystal
Oscillator
The G-03X uses an internal high-precision crystal oscillator to
generate a word sync clock.
Equipped with OCXO
The master clock serving as the reference for this unit is
equipped with an oven-controlled crystal oscillator (OCXO)
offering superior temperature stability. This OCXO contains a
built-in crystal unit and oscillation circuit in an internal
temperature- controlled, compact constant-temperature bath,
resulting in the realization of an extremely high degree of
frequency stability (within ±0.1 ppm at –20°C to 70°C). The
central frequency when shipped from the factory is within
±0.1 ppm.
Up to 192 kHz Word Sync clock production
The G-03X can output following word clocks (sync signals):
44.1 kHz, 88.2 kHz, 176.4 kHz,
48 kHz, 96 kHz, 192 kHz,
Universal clock (100 kHz)
As an additional plus, the output circuitry consists of 3
separate channels with a total of 6 output terminals, thus
offering the capability of handling a variety of audio
equipment controlled by different word clocks. Also, each of
the 3 output channels is switch-selectable between 1xFs, 2xFs
and 4xFs, so you can, for example, get an 88.2 kHz and a
176.4 kHz machine synchronized by connecting them to the
single G-03X.
Universal Clock Output
A universal clock output (100 kHz) has been provided for
Esoteric’s original format. Connection with a universal clock-
compatible device makes it possible to support various
frequency sources.
Ready for connection to external oscillators
Clocks can also be generated by inputting an external 10
MHz reference signal. This system can be further upgraded by
connecting, for example, a rubidium oscillator or an ultra-
high-precision cesium atomic oscillator.
User-Friendly Front Panel for Easy Operation
All functions can be easily controlled simply by pressing a
button located on the front panel, and operating status can
be confirmed at a glance from the highly legible display unit.
Before Use
Read this before operation
< Be careful to avoid injury when moving the unit, on account
of its weight. Get someone to help you if necessary.
< To protect easily scratched furniture, you may stick the felt
supplied with the unit to the feet.
< As the unit may become warm during operation, always leave
sufficient space around the unit for ventilation.
< The voltage supplied to the unit should match the voltage as
printed on the rear panel. If you are in any doubt regarding
this matter, consult an electrician.
< Choose the installation location of your unit carefully. Avoid
placing it in direct sunlight or close to a source of heat. Also
avoid locations subject to vibrations and excessive dust, heat,
cold or moisture.
< Do not place the unit on the amplifier/receiver.
< Do not open the cabinet as this might result in damage to the
circuitry or electrical shock. If a foreign object should get into
the unit, contact your dealer or service company.
< When removing the power plug from the wall outlet, always
pull directly on the plug, never yank the cord.
< Do not attempt to clean the unit with chemical solvents as
this might damage the finish. Use a clean, dry cloth.
< Keep this manual in a safe place for future reference.
Maintenance
If the surface of the unit gets dirty, wipe with a soft cloth or
use diluted neutral cleaning liquid. Be sure to remove any
fluid completely. Do not use thinner, benzine (naphtha) or
alcohol as they may damage the surface of the unit.
