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. Ro-
tate 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 Trim-
mer Capacitor
C1 for maximum
signal strength.
3. Repeat steps 1
and 2 until no
further improve-
ments can be ob-
tained.
