CAUTION:
To prevent the risk of electric
shock, first remove the AC Power
Cord from the MA6700 Rear Panel
before in-
stalling the
TM Mod-
ule into the
MA6700.
1. The semiconductor
devices used in the
TM Module are inherently sensitive to static
electricity even when connected in a circuit,
and can be permanently
damaged by a static
electricity discharge.
When handling the TM
Module follow the pro-
cedures below to insure
against static electricity
damage.
A. Make sure the MA6700 is properly
grounded.
B. Use an approved wrist strap that is
grounded.
C. Remove the TM Module from the Anti-
Static Bag and work with it only after the
above conditions have been met.
General Information
The McIntosh TM2 or TM3 Tuner Module
together with the McIntosh RAA2 AM Antenna
adds AM and FM Radio Broadcast Reception to
the MA6700 Integrated Amplifier. The instruc-
tions in this guide are for installing the TM2 or
TM3 into the MA6700.
The TM2 and TM3 Tuner Modules are not a
user installable product. It must be installed by
the Technical Professionals at a McIntosh Dealer
only.
Installing the Tuner Module
1. If the MA6700 Integrated Amplifier is con-
nected to AC Power, remove the AC Cord
from the Rear Panel.
2. Remove two screws from the MA6700 Rear
Cover and retain the two screws as they will
be used later to secure the Tuner Module.
Refer to figure 1 and 2.
Note: Retain the cover for possible future use.
3. Using the safe handling procedure outlined,
in the “General Information”, remove the
Tuner Module from the Anti-Static Bag.
4. Orient the Tuner Module so the electronic
component parts on the PC Board are facing
upwards and line up the side edges of the
tuner module with the PC Board Guides lo-
cated inside the MA6700 Metal Cage. Refer
to figures 2, 3A (TM2) or 3B (TM3).
5. Insert the Tuner Module all the way into
the MA6700 and secure the Tuner Module
Metal Plate to the rear panel of the MA6700
with the two previously removed screws. Re-
fer to figures 4A (TM2) or 4B (TM3).
6. Proceed to “Connecting the Tuner Module”
to the external Antennas.

Tune to a station with the weakest signal and ori-
ent the RAA2 Antenna for maximum signal with
minimum noise and
distortion. After the
location is determined,
the RAA2 AM An-
tenna may be secured
to a suitable surface by
using two #6 1-3/4 to 2
inches (4.44 to 5.08cm)
long screws, refer to the illustration to the right.
Mounting the RAA2 AM Antenna
1. Using the supplied AM Antenna Shielded
Cable, connect one end into the RAA2 AM
Antenna jack and the other end of the same
cable into the MA6700 Tuner jack labeled
RAA2 AM ANT. Refer to figure 5A with
a TM2 installed and figure 5B with a TM3
installed.
Note: If a longer AM Antenna Cable is needed,
refer to page 5 “Connector and Cable
Information”.
2. Connect a FM Dipole Antenna to the
MA6700 75 Ohm FM ANT Connector. Refer
to figure 5A for a TM2 installed and figure
5B for a TM3.
Note: Optionally, connect a 75 ohm coax
cable from a FM Antenna or cable sys-
tem. For more information about a FM
Dipole Antenna, refer to page 5.
3. Proceed to “Connecting Loudspeakers” in
the MA6700 Owner’s Manual page 14.
Tune to a station with the weakest signal and ori-
ent the top of the “T” shaped Dipole Antenna for
maximum signal with
minimum noise and
distortion. After the
location is determined,
the FM Dipole An-
tenna may be secured
to a suitable surface
by using push pins, refer to the illustration to the
right.
