How To Connect - McIntosh MC501 Owner's Manual

How to Connect

Caution: The supplied AC Power Cord should not be
connected to the Rear Panel of the MC501
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.
1. For Remote Power Control, connect a power control
cable from the Control Center or Preamplifier Power
Control Out to the MC501 Power Control In.
2. Connect cables from the Unbalanced Output of a McIn-
tosh Preamplifier or Control Center to the MC501
Unbalanced Input.
Note: An optional hookup is to use balanced cables.
3. Prepare the Loudspeaker Hookup Cables that attach to
the MC501 Power Amplifier by choosing one of the
methods below:
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.
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 prepared section of
the cable end into the terminal side access 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
terminal. Tighten the top portion of the terminal post
and the set screw to secure the banana plug in place.
Note: The use
of
Banana
Plugs is
for use in
the
United
States
and Canada only.
4. Connect the Loudspeaker hookup cables to the output
terminals that match the impedance of the Loudspeak-
er, being careful to observe the correct polarities. Out-
put impedance connections of 2 ohms, 4 ohms and 8
ohms are provided. If the Loudspeaker's impedance is
in-between the available connections, 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.
5. Attach the supplied Terminal Connections Cover with
the three Mounting Screws (6-32 x 1/4 inch Phillips
Head) to the Rear Panel of the MC501 Amplifier. Refer
to figure 9.
Note: There are two openings on the cover allowing for
the Loudspeaker's Cable to exit the MC501.
6. Connect the MC501 power cord to an active AC outlet.
