Introduction
Congratulations –You have purchased one of the
very finest audio components ever made. This bold
statement is not only measurable, but immediately
apparent from the very first note.
Halcro designs and manufactures the only Super
Fidelity amplifiers in the world. This Super Fidelity
amplifier reproduces with better than 99.9997%
purity of all tones across the entire audio range.
The concept behind the electronic design was to
create an amplifier that did not color the sound with
its own electronic characteristics —to recreate the
original sound as it was at the time of recording.
Please enjoy the Halcro audio experience.
Halcro has enjoyed creating perfect audio
reproduction for the world's music connoisseurs.

Important Safety Information
Symbols
The following symbols are used on this equipment:
The lightning flash with arrowhead
symbol, within an equilateral
triangle, is intended to alert the
user to the presence of
uninsulated ‘hazardous voltage’
that may be of sufficient
magnitude to constitute a risk of
electric shock to a person if
exposed or contacted.
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 following pages.
The ‘CE’ symbol indicates
compliance of this device with the
relevant directives of the
European community including
the EMC (Electromagnetic
Compatibility) and LVD (Low
Voltage Directive) standards.
Warning of electrical shock
hazard. Do not open cover
(or back). There are no user
serviceable parts inside.
Refer servicing to qualified
service personnel.
This symbol is to indicate
that the unit is heavy and
that precautions are
required when lifting or
moving the unit.

Electrical safety
WARNING: This product must
always be connected to a mains
socket outlet with a protective
earth connection.
Only use a suitable approved mains cord complying
with European individual country requirements in
the CE Low Voltage Directive Scheme.
DANGER: Do not open
the cover or back, or
remove any panels, or try
to modify or repair the
Eclipse. Opening the
Eclipse may expose you
to dangerous voltages
and will void the
warranty.
WARNING: The Standby/On mode
switch does not disconnect the unit
from the mains power.
To disconnect the unit from the
mains, switch off the unit at the
mains socket outlet and withdraw
the mains plug from the socket
outlet.
The unit should be installed in a position where the
mains plug is easily accessible. Disconnect the unit
from the mains if it is to be left unused for a long
period.
WARNING: No naked flame sources,
such as lighted candles, should be
placed on the unit.
If naked flame sources tip over they
could result in a fire.

5
Protection from fluids
The Halcro Eclipse amplifiers are designed for indoor
use only and are not protected against liquids. They
must not be exposed to dripping or splashing and no
objects filled with liquids, such as vases, should be
placed on them.
If liquid is accidentally spilled on the device,
immediately disconnect the unit from the mains.
Allow sufficient time for complete evaporation
before using the Eclipse again. If the liquid is
anything other than water, do not use the device
before a qualified service technician has examined it.
Cleaning may be performed with a slightly damp
cloth that has been wrung until nearly dry. Refer to
the section Cleaning on page 26.
WARNING: To reduce the risk of
fire or electric shock, do not
expose this equipment to rain or
moisture.
Do not allow liquids to enter the
unit or contact electrical
terminals.
Service warnings
All compartments are sealed at the factory. If the
seals are broken, the warranty will be void and all
service costs will be charged to the owner.
DANGER: Contains no user
serviceable parts. Do not attempt
to open any of the Eclipse
compartments as this may
expose you to dangerous voltages
and will void the warranty.
Requires an appropriate fuse for continued
protection against the risk of fire (F 10A L 250V or F
15A L 110V). Never bypass or use any other type of
fuse. The fuse is located on the bottom of the lower
panel of the power supply compartment (p13, fig C,
7).
WARNING: Always replace the
fuse with the same type and
rating as specified: F 10A L 250V
or F 15A L 110V as appropriate.
Always disconnect the unit from
the mains before touching the
loudspeaker terminals or
replacing the fuse.

6
Protection from overheating
The Eclipse generates a certain amount of heat and
requires ventilation. Slots and ventilation holes are
provided for ventilation purposes, and to ensure
reliable operation of the product. To prevent fire
hazards, these openings must never be blocked or
covered.
Follow the precautions listed below. If these
precautions are not followed, overheating or failure
may result. Overheating also shortens the working
life of all components.
oDo not block the ventilation slots in the sides
of the unit with any object, including paper,
cloths or curtains
oAvoid placing the unit in a built-in installation
place such as a bookcase or a rack unless you
can provide proper ventilation
oDo not operate the unit inside a cabinet unless
it has adequate ventilation (such as an open
back panel)
oAllow at least 12 in (300mm) clearance around
the unit
WARNING: Do not obstruct
ventilation slots in the chassis.
Lifting or moving
WARNING: Weighs 67kg (148 lb)
per unit. Shipping weight is 88kg
(195 lb) per amplifier crate. Never
lift the amplifier by yourself.
Always use two people to unpack
or move the amplifier. Always
bend at the knees when lifting. Do
not strain your back.
Wiring to the Loudspeaker Terminals to
Class 2 Wiring (US Wiring Regulations)
This equipment has been classified as having a Class
2 loudspeaker output requiring wiring to connect
the output terminals to class 2 according to the
National Electrical Code. Consult a qualified installer
or electrical contractor for further information.

Interference warning - US FCC Regulations
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,
