hole, and tighten the terminal cap until the cable is
firmly clamped into the terminal so the wires cannot
slip out. Refer to figures 4, 5 & 6.

Banana plug connection:
Insert the banana plug into the hole at the top of the

Panel and Left Side. Retain these screws for later use.
Refer to figure 7.

5. Insert the Loudspeaker Hookup Cable Ends through

the openings of the supplied Terminal Connections
Cover and connect to the output terminals that match
the Loudspeakers’ Impedance, being careful to observe
the correct polarities. Output impedance connections of
2 ohms, 4 ohms and 8 ohms are provided. If the Loud-
speakers’ Impedance is in-between the available con-
nections, use the nearest lower impedance connection.

WARNING: Loudspeaker terminals are hazardous live

and present a risk of electric shock. For
additional instruction on making
Loudspeaker Connections contact your
McIntosh Dealer or McIntosh Technical
Support.

6. Attach the Terminal Connections Cover, with the five

previously removed screws, to the Rear Panel of the
MC402 Amplifier. Refer to figure 7.

7. Connect the MC402 power cord to an active AC outlet.

Caution: The supplied AC Power Cord should not be

connected to the Rear Panel of the MC402
Amplifier until after the Loudspeaker Connections
have been made and the supplied protective
Terminal Connections Cover has been installed.
Failure to observe this could result in Electric
Shock.

the MC402 Power Amplifier by choosing one of the
methods below:

Bare wire cable ends:

ends, refer to figures 1,
2 & 3. If the cable is
stranded, carefully twist
the strands together as
tightly as possible.

Note: If desired, the twisted ends can be tinned with

solder to keep the strands together, or attach spade
lug and/or banana connector.

Spade lug or prepared wire connection:
Insert the spade lug
connector or pre-
pared section of the
cable end into the
