WARNING: TO PREVENT FIRE OR SHOCK
HAZARD, DO NOT EXPOSE THIS APPLIANCE
TO RAIN OR MOISTURE.

IMPORTANT SAFETY INSTRUCTIONS

1) Read these instructions.

2) Keep these instructions.

3) Heed all warnings.

4) Follow all instructions.

5) Do not use this apparatus near water.

6) Clean only with dry cloth.

7) Do not block any ventilation openings. Install in accordance
with the manufacturer’s instructions.

8) Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers) that
produce heat.

9) Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades with
one wider than the other. A grounding type plug has two
blades and a third grounding prong. The wide blade or the
third prong are provided for your safety. If the provided plug
does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.

10) Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.

11) Only use attachments/accessories specified by the
manufacturer.

12) Use only with the cart, stand, tripod,
bracket, or table specified by the
manufacturer, or sold with the apparatus.
When a cart is used, use caution when
moving the cart/apparatus combination to
avoid injury from tip-over.

13) Unplug this apparatus during lightning storms or when
unused for long periods of time.

14) Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way,
such as power-supply cord or plug is damaged, liquid has
been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER (OR BACK). NO USER­SERVICEABLE PARTS INSIDE. REFER SERVICING TO
QUALIFIED SERVICE PERSONNEL.

The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated “dangerous voltage” within
the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to
persons.

The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in
the literature accompanying the appliance.

< Do not expose this apparatus to drips or splashes.

< Do not place any objects filled with liquids, such as vases, on

the apparatus.

< Do not install this apparatus in a confined space such as a

book case or similar unit.

< The apparatus draws nominal non-operating power from the

AC outlet with its STANDBY/ON switch in the standby
position.

< The apparatus should be located close enough to the AC

outlet so that you can easily grasp the power cord plug at any
time.

< An apparatus with Class

!

construction shall be connected to

an AC outlet with a protective grounding connection.

< Batteries (battery pack or batteries installed) shall not be

exposed to excessive heat such as sunshine, fire or the like.

< Excessive sound pressure from earphones and headphones

can cause hearing loss.

This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. However, there is no
guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following
measures:

• Reorient or relocate the equipment and/or the receiving
antenna.

• Increase the separation between the equipment and
receiver.

• Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician
for help.

CAUTION

Changes or modifications to this equipments not expressly
approved by TEAC CORPORATION for compliance will void the
user’s warranty.

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.
