The MC 2200 can be housed in the Mclntosh L22 cabinet,
installed in a custom cabinet or, with the addition of RACK
MOUNTING ADAPTERS (RMA 7), mounted in a standard 19
inch rack panel. The MC 2200 weighs 85 pounds (38.6 kg).
In any installation it is necessary to provide proper support
for the weight. The mounting methods described and the
amplifier have been designed to accommodate the weight
so be sure that the panel and its mounting can also handle
the weight.
INSTALLATION IN MclNTOSH CABINET
Remove the instrument and hardware package from the
carton. Remove the MC 2200 from its plastic bag and place
it upside down on the shipping pallet; unscrew the four
plastic feet from the bottom of the chassis. Use the screws
from the plastic feet to secure the instrument to the cabi-
net. Do not substitute longer screws. Longer screws may
penetrate the electronic components in the chassis which
would cause severe damage. Do not overtighten the screws.
INSTALLATION IN A CUSTOM CABINET
The trouble-free life of an electronic instrument is
greatly extended by providing sufficient ventilation to pre-
vent the buildup of high internal temperatures that cause
deterioration. Allow enough clearance so that cool air can
enter at the bottom of the cabinet and be vented from the
top. With adequate ventilation the instrument can be
mounted in any position. The recommended minimum
space for installation is 15 inches (38.1 cm) deep, 17 inches
(43.2 cm) wide, and 8 inches (30.3 cm) high.
Vertical mounting the MC 2200 requires careful con-
sideration. The total weight is transmitted to the panel and
shelf on which the amplifier is to be mounted. Thought
should be given to providing a means for raising the MC
2200 out of the panel. More consideration should be given
to providing adequate ventilation at the panel in vertical
mounting. The heat sinks are at the rear of the chassis
permitting the heat to pass over the entire chassis. It is then
trapped behind the panel causing the overall temperature
to rise. In any case, air flow for cooling can be improved by
the use of a properly installed low noise fan. Adequate
cooling will extend the life of the components.
