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.
<
Do not expose this apparatus to dripps 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 POWER switch in the off position.
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER (OR BACK). NO USER-
SERVICEABLE 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.
WARNING : TO PREVENT FIRE OR SHOCK
HAZARD, DO NOT EXPOSE THIS APPLIANCE

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.
For U.S.A.
This product has been designed and manufactured according to FDA
regulations "title 21, CFR, chapter 1, subchapter J, based on the
Radiation Control for Health and Safety Act of 1968", and is
classified as class 1 laser product. There is not hazardous invisible
laser radiation during operation because invisible laser radiation
emitted inside of this product is completely confined in the
protective housings.
The label required in this regulation is shown .
CAUTION
The product shall not be exposed to dripping or splashing and
that no object filled with liquids, such as vases, shall be placed
on the product.

Before Use
Read this before operation
<
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.
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 floors, etc. you may stick the felt supplied with the
unit to the bottom of the cover feet.

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-0s.
Clocks Generated by Internal High-precision
Oscillator
The G-0s uses an advanced rubidium oscillator (monthly
precision variation: projected within ±0.05ppb) that generates
astonishingly super-accurate clocks.
Ready for connection to external oscillators
It is also possible to connect external reference frequency
oscillators to the G-0s. Using this capability, you can, for
example, readily bring in a higher precision oscillator when
made available in the future.
Universal Clock Output
Some universal players use clocks different from the ones
used by CD players to process both the video and audio
signals at the same time.
The G-0s comes with a 100 kHz clock output intended for
universal players (in PAL FILM mode, the output is switched to
96 kHz). If your universal players are 100 kHz-capable, you
can control them by this high-precision clock.
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-0s 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 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.
