7 Caution: The Loudspeaker Negative Connections are above chassis ground. Do not combine any connections to- gether, ground them or connect with another MC1.2KW. Rear Panel Connections and Switch Connect the MC1.2KW power cord to a live AC outlet. Refer to the rear panel to determine the correct vol...

8 terminals so the lugs cannot slip out. Refer to figures 4, 5 & 6. 4. Connect the loud- speaker hookup ca- ble to the output terminals 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 pro...

13 electronically held to this power level until a higher power peak passes through the amplifier. The meter pointer will then rise to the newer higher indication. If no further power peaks are reached, the meter pointer will very slowly return to its rest position or lower power level. The decay ra...

14 Technical Description McIntosh Laboratory, the company who introduced the world’s first amplifier that could be called “High Fidel- ity”, has done it again. The McIntosh engineering staff has created a power amplifier without compromise, using the most advanced McIntosh circuit design concepts. A...

15 Technical Description cies is less than 0.002%. The true distortion readings on the MC1.2KW are so low, it takes special measuring techniques to make accurate readings. The MC1.2KW can deliver the best possible performance from any type of high quality loudspeaker system. Creating an amplifier wi...

16 Autoformers 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...
