What is in the box
Here is what is in the box besides all the shipping foam:
One MC901 Dual Mono Amplifier
One manual package including this manual
Two Terminal Connection Covers
One AC Power Cord
One McIntosh Output Terminal Wrench
Where to put it
First, you must acknowledge that the MC901 is VERY
HEAVY. When moving the unit, have enough help to
lift the MC901. This will ensure the safety of both you
and the MC901.
The MC901 should be installed upright on the floor
or amplifier stand. Adequate ventilation is important
and will aid in a long trouble-free life of the MC901.
Enclosures are not recommended, but if you wish to
enclose the MC901, you must ensure proper airflow
and allow at least 19 inches (48.3cm) above the unit
and 6 inches (15.2cm) for the front, rear and sides. Do
not remove the feet and make sure there is nothing
obstructing the airflow beneath the MC901. There
must be openings for the warm air to escape above the
unit and a fan would aid in this regard.
Removal of Foam Inserts over
Vacuum Tubes
IMPORTANT!
REMOVE THE FOAM INSERTS OVER THE
VACUUM TUBES PRIOR TO CONNECTING
THE A.C. POWER SUPPLY CORD
.
• To prevent damage to the Tubes during
shipping, there are special foam inserts
surrounding the Tubes of the Power Amplifier
• The Foam Inserts must be removed
from
the MC901 before connecting the AC Power
Supply Cord to the Power Amplifier
• Failure to do so has the potential of a Fire
Hazard, resulting in damage to the MC901
and the surrounding environment
• Follow these instructions for removal of
the packing foam
before connecting the AC
Power Supply Cord to the MC901
To remove the protective foam, it is necessary to
temporarily remove the two Tube Covers. To remove
each Tube Cover:
• Use a Phillips Head #2 screw driver to remove
the two screws that hold each of the Tube
Covers (Figure 01)
• Pull the Tube Cover slightly outward from the
center of the MC901 to clear the lip covering
the top edge of the Tube Cover, and then lift
upward (Figure 02)
• Pull the protective foam straight up off the
Vacuum Tubes (Figure 02)
• Replace the Tube Cover
• Replace the two screws to secure the cover
(Figure 01)
• Do this procedure for each of the two Tube
Covers
Save the protective foam and warning label for
possible future use.
