Features

Up to 192 kHz Word Sync clock production

With the advent of digital equipment using higher sampling
frequencies than ever, 176.4 kHz and 192 kHz word clocks
(sync signals) are made available in addition to conventional

44.1 kHz, 48 kHz, 88.2 kHz and 96 kHz clocks.
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-0Rb.

Clocks Generated by Internal High-precision
Oscillator

The G-0Rb uses an advanced rubidium oscillator (monthly
precision variation: projected within ±0.05ppb) that generates
astonishingly super-accurate clocks.

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, an ultra-high-precision cesium
atomic oscillator used in special applications.

Universal Clock Output

A universal clock output (100 kHz) has been provided for
Esoteric’s original format (96 kHz in the case of PAL-FILM
operation). Connection with a universal clock-compatible
device makes it possible to support various frequency sources.

PAL Film Source-capable Clock Frequencies

The PAL (European TV format) film source is a better image
quality than NTSC discs provide. However, PAL video system is
standardized at 25 frames per second while the PAL film
source discs use the rate of 24 frames per second. So, if these
discs are played back without inserting one additional frame
per second in the process of conversion, the sound pitch may
be higher than is expected. To play PAL film source material
correctly, it is necessary to reduce the play speed by 4% and
play at 24 frames per second. To meet this requirement, the
G-0Rb is designed to output clock frequencies of 96% of
48/96/192 kHz (i.e., 46.08/92.16/184.32 kHz).

To play PAL film source material, connect the Esoteric UX-1 Pi
or any other Universal Player that is equipped to accept 96%
clock frequencies.

Super-rigid Chassis to Ensure
Uncompromised Sound Quality

A rigid chassis featuring a total weight of 18 kg (40 pounds)
helps to provide a stabilized platform for the clock operation.

< 5-mm thick steel base plate completely eliminates external

vibrations.

< Triangular pinpoint feet composed of case-hardened tool

steel ensures enhanced stability against vibration.

Employs carefully selected highest quality
components

Tight-tolerance components are carefully hand-picked and
secured to the rugged chassis to support the high-precision
clock operation.

Before Use

Placement of the unit

High-quality hardened tool steel is used for the pin-point feet,
securely attached to the bottom of the player. Although the
cover feet may appear loose, the weight of the unit causes
them to be firm and secure, and the design effectively damps
and reduces vibration.

< 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

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.

< Each of the A, B, and C channels is switch-selectable between 1xFs, 2xFs, and 4xFs. So you can,

for example, connect an 88.2 kHz and a 176.4 kHz machine to the single G-0Rb and synchronize
them. Three buttons (A, B, and C) are provided on the front panel for each channel.

UNIVERSAL CLOCK OUT terminal

Universal clock signal is an original synchronization format developed by Esoteric.
These terminals output universal clock signals. Connect these OUT terminals to the WORD SYNC
IN terminals of the other matched equipment (UX-1 Pi, P-01,etc.), using a commercially available
BNC coaxial cable (75 ohms).

< 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.

< 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)

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.

< 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.

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

e Check 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.

e Turn on the POWER switch on the rear panel.

Not synchronized

e Check 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.

e If you are using the PAL FILM mode, check to see whether

the connected player supports the PAL FILM frequency (-4%
of the standard frequency).

e Check to see whether the sync outputs on the rear panel are

connected to the acceptable sync inputs of the individual
players.

Desired frequency not selectable with A, B, and C buttons

e Select the proper fundamental frequency in FREQUENCY

MODE before operating the buttons.

Odd sound pitch

e Do not use the PAL FILM mode for NTSC discs or PAL discs

other than film source discs.

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.

< Settings are stored even when power is turned off and the

unit is unplugged.

< When not in use turn off the power switch on the back of the

unit.

< 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.

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.
