Installation
The C45 can be placed upright on a table or shelf, standing
on its four feet. It also can be custom installed in a piece of
furniture or cabinet of your choice. The four feet may be
removed from the bottom of the C45 when it is custom installed as outlined below. The four feet together with the
mounting screws should be retained for possible future use
if the C45 is removed from the custom installation and used
free standing. The required panel cutout, ventilation cutout
and unit dimensions are
shown.
Always provide adequate
ventilation for
your C45. Cool
operation ensures the longest possible operating life for
any electronic
instrument. Do
not install the
C45 directly
above a heat
generating component such as
a high powered
amplifier. If all
the components
are installed in
a single cabinet,
a quiet running
ventilation fan
can be a definite asset in
maintaining all
the system components at the
coolest possible
operating temperature.
A custom

How to Optimize AM Reception
The McIntosh RAA1 Remote AM Antenna is designed to
provide the best in AM Reception especially if the C45 is
located in a noisy reception area. Locate the RAA1 away
from all electronic and electrical interference sources. Rotate the AM Antenna to reduce interference and receive
maximum signal strength.
Notes: The RAAI Remote AM Antenna of the TM1 has been
factory adjusted for optimum reception in a typical
urban location. If you wish to customize the AM
Antenna for the best possible performance in your
location, have your dealer perform the two adjustment
operations listed below. An additional long wire AM
antenna or external ground can be connected to the
GND and ANT terminals if desired.
1. Tune to a weak AM station near 600kHz on the AM
band. Using an appropriate NON - METALLIC tool,
adjust the 600kHz Transformer L1 for maximum signal
strength. Refer to figure 47.
2. Tune to a weak AM station near 1400kHz on the AM
band. Using an appropriate NON - METALLIC tool,
adjust the
1400kHz Trimmer Capacitor
C1 for maximum
signal strength.
3. Repeat steps 1
and 2 until no
further improvements can be obtained.
