Caution: The supplied AC Power Cord should not be con- nected to the Rear Panel of the MC1.2KW Amplifier until after the Loudspeaker Connections have been made and the supplied protective Terminal Connec- tions 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 MC1.2KW (Amplifier One) POWER CONTROL IN.

2.Connect a power control cable from MC1.2KW (Ampli- fier One) POWER CONTROL OUT to the MC1.2KW (Amplifier Two) POWER CONTROL IN.

3.Connect a cable from the Balanced Output of a McIn- tosh Preamplifier or Control Center to the MC1.2KW (Amplifier One) BALANCED INPUT. Place the IN- PUT MODE Switch in the BALANCED Position.

Note: An optional hookup is to use an unbalanced cable and place the INPUT MODE Switch in the UNBAL- ANCED Position.

4.Connect a cable from

the BALANCED

INPUT/OUTPUT of the MC1.2KW (Am-

plifier One) to the

MC1.2KW (Amplifier Two) BALANCED INPUT.

5.Prepare the Loudspeaker Hookup Cable for attachment to the MC1.2KW Power Amplifier:

Bare wire cable ends:

Carefully remove sufficient insulation from the cable ends, refer to figures 1, 2 & 3. If the cable is strand- ed, 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.Banana plugs are for use in the United States and Canada

only. In the United States, when using

the 8 ohm loudspeaker

terminals, it is mandatory to use banana plugs inserted into the top hole of the loudspeaker terminals in order to comply with safety stan- dard requirements.

Connection Method for use inside the United States and Canada only:

Attach the previously prepared bare wire cable ends into the banana plugs and secure the connections. Insert the banana plug only into the hole at the top of the terminal.

Refer to figures A and

Connection Method for use outside the United States and Canada:

Attach the previously prepared bare wire cable ends into the spade lug connectors and secure the connections. Insert the spade lug connector or prepared section of the cable end into the terminal side access hole, and tighten the ter- minal cap until the cable is firmly clamped into the termi- nals so the lugs cannot slip out. Refer to figures 4, 5 & 6.

4.Connect the loudspeaker hookup cable to the output ter- minals that match the impedance of your loudspeaker, 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 loudspeaker 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 ad- ditional instruction on making Loudspeaker Connections contact your McIntosh Dealer or McIntosh Technical Support.

5.Attach the supplied Terminal Connections Cover with the four Phillips Head Mounting Screws (10-32 x 1/2 inch) to the Rear Panel of the MC1.2KW Amplifier.

Refer to figures 7a and 7b ( on the next page).

Note: There are six openings on the bottom edge of the cover to allow the Loudspeaker’s Cable to exit the MC1.2KW. The Rear Chassis Handle has tapped screw openings on both sides for securing the cover.

6.Connect the MC1.2KW power cord to an active AC outlet.
