Precautions for use
- This unit is very heavy, so take care to avoid injury during installation.
- Do not install this unit in a location that could become hot. This includes places that are exposed to direct sunlight or near a radiator, heater, stove or other heating equipment. Moreover, do not place it on top of an amplifier or other equipment that generates heat. Doing so could cause discoloration, deformation or malfunction.
- When installing this unit, leave a little space (at least 20 cm or 8") between it and walls and other devices in order to allow good heat dissipation.
If you put it in a rack, take precautions to prevent overheating by leaving at least 5 cm (2") open above the top of the unit and at least 10 cm (4") open behind the unit. Failure to provide these gaps could cause heat to build up inside and result in fire.
- Place the unit in a stable location near the audio system that you will use with it.
- Do not move the unit during use.
- Be careful to avoid injury when moving the unit due to its weight. Get someone to help you if necessary.
- The voltage supplied to the unit should match the voltage printed on the rear panel. If you are in any doubt regarding this matter, consult an electrician.
- Do not open the body of the unit as this might result in damage to the circuitry or cause electric shock. If a foreign object should get into the unit, contact your dealer.
- Do not place anything, not even CDs, CD-Rs, LP records or cassette tapes, on top of the unit. Doing so could cause damage.
- When removing the power plug from an outlet, always pull directly on the plug; never yank on the cord itself.
The rubidium unit is attached loosely inside this equipment because this contributes to improving the sound quality.
For this reason, before shipment from the factory, transportation locking screws have been attached through the bottom of the G-01X to protect the rubidium unit from vibration during transportation.
- After removing the transportation locking screws, save them in a safe place because you will need to reattach them before transporting the unit in the future.

This unit uses a rubidium oscillator to generate its reference master clock.
Since rubidium oscillators have extremely high precision and high stability, they are used in GPS satellites and similar applications. In this master clock generator, we have incorporated a rubidium unit because it also features short-term stability and high waveform quality as well as the ability to be used for many years without calibration. These and other characteristics make it excellent for meeting the demands of a master clock generator in a high-end audio system.
When shipped new, this unit is set to Rubidium mode, and will use the built-in rubidium unit to generate the reference clock.
With a frequency precision of ±0.05 ppb (when shipped new) and a frequency stability of less than ±0.1 ppb at temperatures ranging from -20^ to +65^ , this rubidium unit is able to provide an extremely stable audio clock.
This master clock generator can also be connected to a GPS receiver for GPS-linked operation.
By inputting a GPS 1pps signal through the reference frequency input (EXT IN) connector and enabling 1pps mode, the built-in rubidium unit can be made to follow the GPS.
In most cases with GPS receiver output, the degree of short-term stability depends on the GPS receiver. However, since the degree of long-term stability depends on the GPS satellite, this mode allows this master clock generator to synchronize with the accuracy provided by the long-term stability of the GPS satellite (about 0.001 ppb) while utilizing the high quality of the rubidium unit.
In order for the rubidium unit to synchronize with a 1pps input signal, the signal must have accuracy and stability that are equivalent to GPS.
If you are using a GPS receiver that does not have 1pps output, this master clock generator can itself generate a 1pps signal from the GPS receiver's +10MHz output signal. To do this, use this unit's 10MHz mode to make the rubidium unit operate synchronized with the GPS.

When using the CLOCK OUT connectors
1) Set the clock reference frequency to 44.1 or 48 kHz.
Press the MENU button to open the FREQ menu and use the A and B buttons to set the frequency mode (pages 16–17).
MENU
A
B
44 (44.1 kHz)
Use for playback of CDs, Super Audio CDs and other 44.1kHz sources.
48 (48 kHz)
Use for playback of DVDs, DATs and other 48kHz sources. (Some DVDs and DATs are recorded at 44.1 kHz. In this case, use the 44.1kHz setting.)
- When using only universal clock (100 kHz or 10 MHz), either setting is fine.
- Only use 44EXP or 48EXP for frequencies that are not covered by the 44 and 48 modes (page 17).
2) Use the A and B buttons to set the frequencies sent to connected devices (page 13).
A
B
When setting 10MHz OUT connectors
Press the 10MHz button to turn output on and off.
Use the menu to set which 10MHz OUT connectors (1–4) to use (page 18).
- If you do nothing for five or more seconds, setting mode will end and ordinary display will resume. (If DISP is set to SHORT, this will happen after three seconds.)
10MHz
3 On the connected devices, turn clock sync ON (or set to slave mode).
Read the owner's manual for each device for instructions on how to set their clock sync status properly.
If you connect this unit to devices from other manufacturers, be sure to read the manuals of those devices to confirm the clock frequencies that they can receive.
Some devices require the clock frequency to be set to the same value as the audio signal sampling frequency.
Some dual AES connections might require that the clock frequency be set to half of the audio signal frequency.
- Due to the nature of the rubidium oscillator, continuous operation stabilizes the precision of operation, so we recommend turning the preheat (PrHEAT) setting ON (page 18).
●Settings are retained even when the power is turned off. - Once settings have been made, those settings can be used when the power is turned on again.
Set the frequency mode according to the type of disc to be played or device being used (page 17).
Clock output frequency setting
You can set the clock frequency output from the CLOCK OUT connectors.
- This unit has 2 pairs (A and B) of clock outputs that can be separated further into 4 individual outputs (A1, A2, B1 and B2). You can set the clock frequency independently for each of these outputs.
- By default, the A and B outputs are set to be used as pairs.
Setting A and B outputs by pair (default)
When you change the A setting, the output frequency is set for both A1 and A2 simultaneously. Follow the same procedure for B.
When "A >" or "B >" appears, pressing the A or B button changes the output frequency of that pair. Press repeatedly to cycle through the options.
- Press and hold the A or B button for at least two seconds to set A2 or B2, respectively (See "Setting A2 or B2").
- If you do nothing for five or more seconds, setting mode will end and ordinary display will resume. (If DISP is set to SHORT, this will happen after three seconds.)
Setting A1, A2, B1 or B2
Press the A button for at least two seconds until "A2>" appears. Then, press the A button to change the A2 setting. You can set different clock frequencies for A1 and A2. Follow the same procedure for B.
Setting A1 or B1
When A2 is set to any value that is not the same as the A1 setting, when "A1>" appears, press the A button to change just the A1 output frequency. Follow the same procedure for B.
Setting A2 or B2
Press the A or B button for at least two seconds to set A2 or B2.
When "A2>" appears, press the A button to change just the A2 output frequency. Follow the same procedure for B.
- To set A1 after setting A2, press the A button again after returning to the ordinary display.
- If you set A2 to the same value as A1, "A" will appear again, and you can set the output frequency used by both outputs in the A pair simultaneously. Follow the same procedure for B (See "Setting A and B outputs by pair (default)").

Display illumination time setting
DISP>***
You can set the amount of time that the clock frequency is shown on the display to ON, LONG or SHORT.
- We recommend setting this to LONG or SHORT because display brightness irregularities might occur if the same information is shown without change for a long time.
ON
In this mode, the display always stays lit.
Set the brightness of the display with the dimmer setting.
LONG
When ordinary display continues without any operation being conducted for about 20 seconds, the display will automatically turn off.
SHORT
When ordinary display continues without any operation being conducted for about three seconds, the display will automatically turn off.
Dimmer setting
DIMMER>***
When the display illumination time setting (DISP) is ON, you can adjust the brightness of the unit's display and indicators.
- You can also change this setting using the DIMMER button on a remote control that is included with another Esoteric product such as the P-02X, K-01X or K-03X.

- When set to "DIMMER>0", the display will not be lit.
- When unlit, pressing a button will cause the display to light for a few seconds.
- When set to a value other than "DIMMER>3", error messages and settings menu items will be shown at normal brightness ("DIMMER>2").
Preheating setting
PrHEAT>\*\*\*
Use to turn ON/OFF preheating when the unit is off.
OFF
The POWER button turns the rubidium oscillator on/off with the unit.
ON
This turns the power for the rubidium oscillator on regardless of the POWER button setting. This shortens the amount of time until the oscillator stabilizes after the unit is turned on.
- Due to the nature of the rubidium oscillator, continuous operation stabilizes the precision of operation, so we recommend turning this ON.
- When the unit power is off, clock is not output even though the rubidium oscillator is operating.
- If the rubidium oscillator is always on, the unit will consume considerably more power when the unit is off.
Reference clock setting
Rb>***
INT
The built-in rubidium unit is used for the reference clock.
+1pps
Use this mode when a GPS 1pps signal is input through the reference frequency input (EXT IN) connector to operate with the built-in rubidium unit synchronized to the GPS.
- Synchronization of the rubidium unit with a 1pps signal takes about ten minutes.
While synchronizing, the LOCK indicator blinks and "1ppsLCK-ING" appears on the display.
+10MHz
Use this mode when inputting the 10MHz output from a GPS receiver to the reference frequency input (EXT IN) connector. (Use when the GPS receiver does not have a 1pps output.) This unit will internally generate a 1pps signal and operate with the built-in rubidium unit synchronized to the GPS.
- When using +1pps or +10MHz mode, since synchronizing with the built-in rubidium oscillator takes a very long time, we strongly recommend setting PrHEAT (preheating) to ON.
10MHz OUT connector 1 output setting
10M_1>***
Use to set the output for the 10MHz OUT 1 connector.
ON
This enables it.
OFF
This disables it.
10MHz OUT connector 2 output setting
10M_2>***
Use to set the output for the 10MHz OUT 2 connector.
ON
This enables it.
OFF
This disables it.
10MHz OUT connector 3 output setting
10M_3>***
Use to set the output for the 10MHz OUT 3 connector.
ON
This enables it.
OFF
This disables it.
10MHz OUT connector 4 output setting
10M_4>***
Use to set the output for the 10MHz OUT 4 connector.
ON
This enables it.
OFF
This disables it.
Messages
Maintenance
PLL LCKING
The 10MHz reference clock from the built-in rubidium oscillator is being locked by the internal PLL circuit.
When locking completes, this message will disappear.
o Ordinarily, only a few seconds are needed until locking completes (PLL locking time), but it can take up to a minute depending on the operating temperature and other factors.
o If locking cannot be completed because input conditions are not met when set to +10MHz, the message will continue to be displayed.
Check the input reference clock.
Rb LOCKING
The output of the ruhidium unit is being stabilized (when preheating or changing the reference clock).
Use a soft dry cloth to wipe the surface of the unit clean.
For stubborn smudges, use a damp cloth that has been thoroughly wrung out to remove excess moisture.
For safety, disconnect the power plug from the outlet before cleaning.
o Never spray liquid directly on this unit.
Do not use chemically-treated wipes, thinner or similar substances because they could damage the surface of the unit.
o Avoid allowing rubber or plastic materials to touch the unit for long periods of time because they could damage the cabinet.
1ppsLCKING
This sometimes appears when the reference clock is set to +10MHz or +1pps.
This message appears during synchronization with a 1pps signal that has been converted by this unit from an input 10MHz clock (+10MHz) or with an input 1pps clock (+1pps).
o Synchronization sometimes takes a long time.
o If the input signal precision does not meet the requirements of this unit, synchronization will not occur even after ten minutes and "1ppsLCKING" will continue to appear on the display. Check the input signal precision. If it does not meet the requirements of this unit, set the reference clock to INT.
