Input Terminals
When connecting the Loudspeaker Hookup Cables to
the XR100 Loudspeaker Input Terminals please follow
the steps below:
1. Rotate the end of the Input Ter-
minal Post counterclockwise
until an opening appears. Refer
to figures A and B.
2. Insert the Loudspeaker hookup
cable into the Input Terminal
Post opening or the cable spade
lug around the center post of the
Input Terminal. Refer to figure
C.
3. Rotate the end of the Input Ter-
minal Post clockwise until it is
finger tight. Refer to figure D.
4. Place the supplied McIntosh
Wrench over the end of the
Input Terminal and rotate it one
quarter of a turn (90° ) to secure
the Loudspeaker Cable Connec-
tion. Do not over tighten. Refer
to figure E.
How to Connect using a single Amplifier
Caution: The AC Power Cord should not be connected to
the Amplifier until after the Loudspeaker Con-
nections have been made. Failure to observe
this could result in Electric Shock.
1. For illumination of the XR100 Loudspeaker McIn-
tosh Name Plate, connect a Power Control Cable
from the Power Amplifier (or Integrated Amplifier)
Power Control Output 1 to the XR100 POWER
CONTROL IN.
2. Connect a second Power Control Cable from the
first XR100 Loudspeaker POWER CONTROL
OUT to the next XR100 POWER CONTROL IN.

3. Connect any additional McIntosh Loudspeakers
with illuminated McIntosh Name Plates in a simi-
lar manner, as outlined in steps 1 and 2.
When connecting a XR100 Loudspeaker to an ampli-
fier it is very important to use cables of adequate size,
so there is little to no power loss in the cables. The
size is specified in Gauge Numbers or AWG (Ameri-
can Wire Gauge). The smaller the Gauge number, the
Opening
larger the wire size:

4. Prepare Loudspeaker cables by choosing one of the
methods below:
Bare wire cable ends:
Carefully remove sufficient insulation from
the cable ends, refer to figures 12, 13 & 14. If
Figure E
the cable is
stranded, care-
fully twist the
strands together
as tightly as
possible.
Notes: 1. If desired, the twisted ends can be tinned

with solder to keep the strands together.
2. The prepared bare wire cable ends may be
inserted into spade lug connectors.
3. Banana plugs are for use in the United
States and Canada only.

Canada only:
5. Attach the previously prepared bare wire cable
ends into the banana plugs and secure
the connections. Refer to figure F.
6. Rotate the top of the Output Terminal
Post clockwise until it is finger tight.
Refer to figure G. Then using the
McIntosh Wrench, rotate the top of
the Output Terminal one quarter of
a turn (90° ). Do not over tighten.
Refer to figure E.

7. Referring to figure H and the illus-
8AWG
tration on the next page,
connect the Loudspeaker
hookup cables with ba-
nana plugs into the hole
at the end of the terminal
to the XR100 Negative (-)
LOW Input Terminal and Positive (+) LOW Input
Terminal.
Note: It is important to maintain the correct polarity
at both ends of the Loudspeaker cables.
8. Connect the other end of the Loudspeaker cables
coming from the XR100 Negative (-) and Posi-
Figure 14
tive (+) LOW Input Terminals to the Left Channel
Negative (-) and Positive (+) 8 Ω Output Terminal
of the Amplifier.
9. Refer to steps 7 thru 8 to connect the second
XR100 Loudspeaker in a similar manner to the
Amplifiers.
