4 Performance Features Connector Information, Introduction and Performance Features Introduction • • • • • Power Output The MC207 consists of seven Power Amplifier Channels, each capable of 200 watts into 4 ohm or 8 ohm Loudspeak- ers with less than 0.
5 Dimensions The following dimensions can assist in determining the best location for the MC207. There is additional informa- tion on the next page pertaining to installing the MC207 into cabinets. Dimensions 17- 1/2 " 44.45cm 8- 7/8 " 22.54cm Front View of the MC207 Rear View of the MC207 9- 7/16 " 23.
6 Inst allation The MC207 can be placed upright on a table or shelf, standing on its four feet. It also can be custom installed in a piece of furniture or cabinet of your choice. The four feet may be removed from the bottom of the MC207 when it is custom installed as outlined below .

15 How to Operate and Read the Power Output Meters How to Operate Power On W ith the POWER Switch set to the REMOTE Position, the MC207 will turn On or Off when an A/V Control Center turns On or Off. For manual operation, rotate the POWER Switch to the ON or OFF Position as desired.
16 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.
17 T echnical Description higher distortion of many non-feedback designs. All transistors are selected to have nearly constant cur- rent gain over the entire current range they must cover . Output transistors in par- ticular , have matched uniform current gain, high current-bandwidth product and large active region safe operating area.
18 Figure 17 The MC207 can easily drive 4 ohm speakers, with their high current demand. Additionally , the MC207 can be used with 8 ohm speakers, and deliver equal power . McIntosh’ s new DPM TM design enables it to run on higher voltage rails when connected to less current-hungry 8 ohm speakers and still deliver 200 watts.
19 T echnical Description, con’t but the inaudible ultrasonic dis- tortion is also undesirable, since it can damage valuable Loudspeaker System tweet- ers. Y ou will never experi- ence the harsh and damaging distortion due to clipping. The Power Guard circuit is a waveform comparator , monitoring both the input and output wave- forms.
20 Figure 23 Control Center . When the A/V Control Center is switched On a digital “1” (+5V) signal operates the power relay in the MC207. The MC207 also has a remote Power Control input for Zone B operation (two of the seven channels).
