Amplification for your home theater system
must meet a stringent set of requirements. It
must have a dynamic range to suit the most
explosive action, the subtlest of tender
moments and all that lies between. It must not
distract with any intrusive distortion, and it
must deliver all of this with pinpoint timing and
accuracy.
Each Halcro Logic multi-channel amplifier is a
powerhouse that responds precisely to each
of these demands, utilizing LYRUS™
technology to ensure the maximum detail and
impact is drawn from all soundtracks.
LYRUS™ amplification technology was
developed by Bruce Candy, one of the
world's leading commercial physicists and a
passionate audiophile. LYRUS™ is the only
genuine high-performance Class D
amplification technology on the world market.
It delivers very low levels of Total Harmonic
Distortion (THD), the key feature of the Halcro
range of monoblock and stereo amplifiers.

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.
.
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 no
open the cover o
back, or remove any
panels, or try to
modify or repair the
MC20/30/50/70.
Opening the
MC20/30/50/70 may
expose you to
dangerous voltages
and will void the
warranty.
WARNING: The Standby/On
button 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 resul in a fire.t
Protection from fluids
The Halcro Logic MC20/30/50/70 units 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 MC20/30/50/70
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 on
page 27.
Cleaning
on
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 use
serviceable parts. Do not
attempt to open any of the
MC20/30/50/70
compartments as this may
expose you to dangerous
voltages and will void the
warranty.

Requires F 10A L 250V fuse for continued
protection against the risk of fire. Never
bypass or use any other type of fuse. The fuse
is located on the rear panel of the multichannel power amplifier (13).
WARNING: Always replace the
fuse with the same type and
rating as specified:
F10AL250V.
Always disconnect the unit
from the mains before
touching the loudspeaker
terminals or replacing the fuse.
Protection from overheating
The MC20/30/50/70 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.
The MC20/30/50/70 may be stacked on top
of a Halcro Logic SSP80/100 amplifier but
overheating may result if ventilation is
inadequate. Ensure there is at least 4 in
(10 cm) above the uppermost unit for
ventilation.
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.
• do not block the ventilation holes in the
top or bottom of the unit with any object,
including paper, cloths or curtains
• do not place the unit on a soft surface
such as a rug, or carpet with a thick pile,
into which it could sink
• avoid placing the unit in a built-in
installation place such as a bookcase or a
rack unless you can provide proper
ventilation
• do not operate the unit inside a cabinet
unless it has adequate ventilation (such
as an open back panel)
• allow at least 4 in (10 cm) on all sides of
the unit (except the bottom)
WARNING: Do not obstruct
ventilation slots in the chassis.

Installation
Ensure you have read the Important Safety
Information on page 5, before installing your
Halcro multi channel power amplifier.
If you require assistance in the unpacking and
installation of your Halcro multi channel power
amplifier, please contact your dealer.
Storing packaging
The packaging is custom designed to prevent
damage from occurring during transport.
Store the packaging in a dry location.
Unpacking
Unpack the unit carefully, noting that all
components are present and undamaged.
Your carton should contain the following
items:
• MC20, MC30, MC50 or MC70, as
ordered
• mains supply cable (USA and EU)
• three feet (for stacking)

Positioning
We suggest that the Halcro multi channel
power amplifier be positioned as near to your
front loudspeakers as practical. The unit
houses several heat sinks that are used to
dissipate heat. The airflow to these should not
be interrupted. Ensure there is at least four
inches (ten centimeters) clearance around the
vents.
Do not connect to mains power
until all the connections are
made and checked.
