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.

WORD CLOCK OUT terminals
These terminals output precise word synchronization signals. Connect these OUT terminals to the
WORD SYNC IN terminals of the other digital equipment (CD player, D/A converter, etc.), using a
commercially available BNC coaxial cable (75 ohms).
<Each of the A, B, and C channels is switch-selectable between 1xFs, 2xFs, 4xFs and 100 kHz. So
you can, for example, connect an 88.2 kHz and a 176.4 kHz machine to the single G-03X and
synchronize them. Three buttons (A, B, and C) are provided on the front panel for each channel.
10MHz IN terminal
You can use the input of external 10MHz reference frequency. Connect this terminal to the
output terminal of the external 10MHz oscillator. Use a commercially available BNC coaxial cable
for connection.
When a 10 MHz signal is input to this terminal, the unit automatically generates a clock using an
external 10 MHz oscillator (instead of the internal crystal oscillator).
<If the output level of the oscillator is outside the allowable input range of this unit, the oscillator
cannot be used. Refer to the oscillator manual for information on the output level and accuracy
of the oscillator.
SIGNAL GND connection
Audio quality might be slightly improved by connecting the SIGNAL GND terminal of another
device using commercially available vinyl-coated wire.
<Note that this is NOT an electrical safety ground (earth).
Power cord receptacle
After all other connections have been made, insert the supplied AC power cord into this
receptacle, then connect the other end of the power cord into the wall socket.
<Ensure that your AC voltage corresponds to the voltage marked on the rear panel of the unit.
Consult a qualified electrician if you are in doubt.
<Use only the supplied Esoteric power cord. Use of other power cords may result in fire or electric
shock. Unplug the power cord when you are not going to use the unit for an extended period of
time.

few minutes before the oscillator is ready for operation.
During the process of pre-heating, “44.1 kHz” or “48 kHz”
indicator blinks on the display.
Select the appropriate frequency mode using the
FREQUENCY MODE button.
44.1kHz:
Select this for playback of CD, Super Audio CD, etc.
48kHz:
Select this for playback of DVD, DAT, etc.
<When you intend to select 100 kHz in step 3, either 44.1 kHz
or 48 kHz may be selected.

Select the frequency of the word clock for each line by
pressing the A, B or C button.
When the connected device is compatible with a universal
clock (100 kHz):
“100 kHz” is recommended.
Although the CD and Super Audio CD frequencies are
multiples of 44.1 kHz while the DVD frequency is a multiple
of 48 kHz, the universal clock (100 kHz) enables
compatibility with any disc. The lack of the need to switch
the frequency mode for each disc results in considerable
convenience.
<Please refer to the manual or other references in advance to
determine whether or not the connected device is
compatible with a universal clock (100 kHz).
The following models are not compatible with a universal
clock:
P-0, P-0s, P-70, P-70 (upgraded), D-70, D-70 (upgraded)
When the connected device is NOT compatible with a
universal clock (100 kHz):
Set the frequency as high as the connected units will allow for
synchronization.
Note:
Select 44.1 kHz for the P-0 or P-0s.
Select 88.2 kHz for the P-70.
Set the connected units to the slave mode (word
synchronization input mode).
Read the instructions of each component to turn Word Sync
on.
Example:
D-01: select “Rb IN” using the WORD button.
D-70 upgraded: select “WORD+RAM” using the CLOCK
MODE switch (front panel), then select “IN M1” using the
remote control unit.
P-01: select “Rb IN” using the WORD button.
P-70/P-70 upgraded: turn ON the WORD SYNC switch (front
panel), then set the PLL filter switch (back panel) to
“MODE2”.
X-01: select “Word M1 ON” using the CLOCK MODE button.

<When you turn on the power or you operate other buttons,
the display temporarily lights at full brightness. It is dimmed
after the clock signal is stabilized (after “44.1 kHz” or “48
kHz” indicator stops blinking and lights steadily).
NOTE:
If you connect this unit to other manufacturers units, be sure
to read the manuals of those devices to confirm the frequency
range of synchronization.
Dual AES connection will require you to set the clock
frequency at one half of the audio signal frequency.
<Settings are stored even when power is turned off and the
unit is unplugged.
<When not in use, turn the G-03X off.
<Once settings have been made, those settings can be used
simply by turning on the power the next time the unit is used.
Switch the frequency mode using the FREQUENCY MODE
button depending on the disc to be played or device.
<Although the CD and Super Audio CD frequencies are
multiples of 44.1 kHz while the DVD frequency is a multiple
of 48 kHz, the universal clock enables compatibility with any
disc. The lack of the need to switch the frequency mode for
each disc results in considerable convenience.

Troubleshooting
In case you experience any problem with this unit, please take
the time to look through this chart and see if you can solve the
problem yourself before you call your dealer.
No power
eCheck the connection to the AC power supply. Check and
make sure the AC source is not a switched outlet and that,
if it is, the switch is turned on. Make sure there is power to
the AC outlet by plugging another item such as a lamp or
fan.
eTurn on the POWER switch.
Not synchronized
eCheck to see if the current word clock output is supported
by the connected players. If necessary, select a word clock
frequency that is appropriate for the individual players.
There are occasions where the word clock available for
synchronization varies depending on the connection and
settings of the individual players. For details, consult the
manual for each player.
Desired frequency not selectable with A, B, and C buttons
eSelect the proper fundamental frequency in FREQUENCY
MODE before operating the buttons.
If normal operation cannot be obtained, unplug the power
cord from the outlet and plug it again. This resets the
internal micro-computer which can be disturbed during
electrical storms, power interruptions, et cetera.
