12 Rear Panel Connections Rear Panel Connections The identification of Rear Panel Connections for the MC2KW Output Module and MC2KW Power Modules are located on separate folded sheets contained in the Owner ’ s Manual Packet.
13 These two pages contain information for connecting to- gether the McIntosh MC2KW Output Module and the MC2KW Power Modules; and that combination to the C1000 Preamplifier . McIntosh Power Control connections allow for unified audio system operations; one push-button press to switch the entire system On or Off.
14 How to Connect a Loudspeaker to the MC2KW Output Module Caution: The supplied AC Power Cords should not be connected to the Rear Panel of the MC2KW Output Module and both of the Power Modules until after the Loudspeaker Connections have been made and the supplied protective T erminal Connections Cover has been installed.

19 T echnical Description McIntosh Laboratory , the company who introduced the world’ s first amplifier that could be called “High Fidelity”, has done it again. The McIntosh engineering staf f has cre- ated a power amplifier without compromise, using the most advanced McIntosh circuit design concepts.
20 T echnical Description quencies is less than 0.002%. The true distortion readings on the MC2KW Power Amplifier are so low , it takes special measuring techniques to make accurate readings. The MC2KW Power Amplifier can deliver the best possible per- formance from any type of high quality Loudspeaker Sys- tem.
21 Autoformer All solid state power amplifier output circuits work best into what is called an optimum load. This optimum load may vary considerably from what a loudspeaker requires. In the case of more than one loudspeaker connected in parallel, the load to the power amplifier may drop to two ohms or even less.
22 T echnical Description, con’t tions. The dif ferent types of protection circuits incorporated in the MC2KW Power Amplifier insure a long and safe op- erating life. This is just one of the many characteristics of McIntosh Power Amplifiers that make them world famous.
23 music demands and guarantees an excellent signal to noise ratio. Refer to figure 27. The MC2KW Output Module contains the low voltage regulated power supplies for each of the MC2KW Power Modules and for the Input Audio circuitry located inside the MC2KW Output Module.
