The lightning ash with arrowhead, within an equilateral
triangle, is intended to alert the user to the presence of
uninsulated “dangerous voltage” within the product’s en-
closure that may be of sufcient 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 REDUCE RISK
OF FIRE OR ELECTRICAL
SHOCK, DO NOT EXPOSE
THIS EQUIPMENT TO RAIN OR
MOISTURE.

8. Do not install near any heat sources such as
radiators, heat registers, stoves, or other appa-
ratus (including ampliers) that produce heat.
9. Do not defeat the safety purpose of the polar-
ized 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 t 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 specied by
the manufacturer.
12. Use only with the cart, stand, tripod, bracket,
or table specied by the manu-
facturer, or sold with the appa-
ratus. 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 qualied service person-
nel. 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.
15. Do not expose this equipment to dripping or
splashing and ensure that no objects lled
with liquids, such as vases, are placed on the
equipment.

IMPORTANT SAFETY

3
Six foot, 2 conductor shielded, with two 1/8 inch
stereo mini phone plugs.
2. For additional connection information, refer to the
owner’s manual(s) for any component(s) connected
to the MC452.
3. The MC452 mutes the speaker output for approxi-
mately two seconds when first turned on.
4. For the best performance and safety it is important
to always match the impedance of the loudspeaker
to the Power Amplifier connections. Refer to “How
to Connect” pages 8 thru 11.
Note: The impedance of a Loudspeaker actually var-
ies as the Loudspeaker reproduces different
frequencies. As a result, the nominal impedance
rating of the Loudspeaker (usually measured at
a midrange frequency) might not always agree
with the impedance of the Loudspeaker at low
frequencies where the greatest amount of power
is required. Contact the Loudspeaker Manufac-
turer for additional information about the actual
impedance of the Loudspeaker before connecting
it to the McIntosh MC452.
5. In the event the MC452 over heats, due to improper
ventilation and/or high ambient temperature, the
protection circuits will activate. The Front Panel
Power Guard LED will continuously indicate ON
and the audio will be muted. When the MC452 has
returned to a safe operating temperature, normal
operation will resume.
6. When discarding the unit, comply with local rules
or regulations. Batteries should never be
thrown away or incinerated but disposed
of in accordance with the local regulations
concerning battery disposal.
7. For additional information on the MC452
