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.
