How to Connect the MC352
1. Connect the MC352 power cord to a live AC outlet.
2. Connect a power control cable from the control center
Power Control Out to the MC352 Power Control In.
3. Prepare the loudspeaker hookup cables as follows:
A. Carefully remove sufficient insulation from the
loudspeaker cable ends to just fit within the bind-
ing post with no exposed
wire accessible. Refer to
figure 1.
B. If the cable is stranded,
carefully twist the strands
together as tightly as pos-
sible. Refer to figures 2
& 3.
Note: If desired, the
twisted cable section
can be tinned with a
solder iron to keep
the strands together
and/or attach
appropriate
connector ends.
C. Insert the bare section of the cable end or connec-
tor into the access hole, and tighten the terminal
nut clockwise until the cable is firmly clamped
into the terminal so the wires cannot slip out. Re-
fer to figure 4.
D. Insert the bare section of the cable end or connec-
tor into the access hole, and tighten the terminal
nut clockwise until the cable is firmly clamped

into the terminal. Refer to figures 5 & 6.
Note: The bare sections of the cable ends or the non
insulated part of the connectors must not be exposed on
either side of the terminal access hole.
E. Repeats Steps A through D for each speaker cable
used with the amplifier.
4. Connect the loudspeaker cables to the appropriate termi-
nals for your loudspeakers, being careful to observe the
correct polarities. Output impedance connections of 2
ohms, 4 ohms and 8 ohms are provided.
If the impedance of your loudspeakers
is rated at other than the listed imped-
ance connections, use the nearest lower
connection.
5. Install the plastic protective loudspeaker
terminal covers that were supplied with
your amplifier. Refer to figure 7.
6. Connect a cable from the balanced outputs of a control
center to the MC352 balanced Input connectors for both
audio channels and power control.
Note: An optional hookup is to use unbalanced cables from a
McIntosh Control Center to Unbalanced Inputs of the
MC352.
