Caution: Do not connect the AC Power Cord to the
MC2152 Rear Panel until after the Loudspeaker
Connections are made. Failure to observe this
could result in Electric Shock.
The connection instructions below, together with the
MC2152 Connection Diagram located on the separate
folded sheet “ Mc1A ”, is an example of a typical audio
system. Your system may vary from this, however the
actual components would be connected in a similar
manner. For additional information refer to “Connec-
tor and Cable Information” on page 6.
1. For Remote Power Control, connect a power control
cable from the Audio Preamplifier Power Control
Main Output Jack to the Power Amplifier POWER
CONTROL IN Jack.
2. Connect XLR cables from the Balanced Main
Output connector of the Audio Preamplifier to the
Power Amplifier BALanced INPUTS. Place the
INPUT Switch in the BALanced Position.
Note: An optional hookup is to use unbalanced
cable and place the INPUT MODE Switch
in the UNBALanced Position.
This McIntosh MC2152 Power Amplifier is designed
for Loudspeakers with an impedance of 2 ohms, 4
ohms or 8 ohms. Connect a single Loudspeaker only
to the Output Terminals.
When connecting Loudspeakers to the MC2152
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 (American Wire
Gauge). The smaller the Gauge number, the larger the
wire size:

3. Prepare the Loudspeaker Hookup Cable for attach-
ment to the MC2152 Power Amplifier:
Bare wire cable ends:
Carefully remove sufficient insulation from the
cable ends, refer to figures 1, 2 & 3. If the cable
is stranded, carefully 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:
4. Attach the previously prepared
bare wire cable ends into the ba-
nana plugs and secure the connec-
tions. Refer to figure F.
5. Rotate the top of the Output Termi-
nal 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.
6. Referring to figure H, connect
the Loudspeaker hookup cables
with banana plugs into the hole
at the top of the MC2152 Nega-
tive (-) and Positive
(+) Output Termi-
nals. The Positive
Terminals are inden-
tified as 4Ω (ohms),
8Ω (ohms) or 16Ω

How to Connect for Stereo Operation
Output Terminals
When connecting the Loudspeaker Hookup Cables to
the MC2152 Power Amplifier Output Terminals please
follow the steps below:
1. Rotate the top of the Output Terminal Post coun-
terclockwise until an opening
appears. Refer to figures A and
B.
2. Insert the Loudspeaker hookup
cable into the Output Terminal
Post opening or the cable spade
lug around the center post of
the Output Terminal. Refer to
figure C.
3. Rotate the top of the Output
Terminal Post clockwise until it
is finger tight. Refer to figure D.
4. Place the supplied McIntosh
Wrench over the top of the Out-
put Terminal and rotate it one
quarter of a turn (90° ) to secure
the Loudspeaker Cable Connec-
tion.
Do not over tighten.
