Caution: Do not connect the AC Power Cord to the
MC1502 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
MC1502 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
“Connector 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 MC1502 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 MC1502
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
attachment to the MC1502 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
banana plugs and secure the
connections. Refer to figure F.
5. Rotate the top of the Output
Terminal Post clockwise until
it is nger tight. Refer to gure
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 gure E.
