Installation 17" Installation The MC8207 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 MC8207 when it is custom installed as outlined below. The four feet together with the mounting screws should be retained for possible future use if the MC8207 is removed from the custom installation and used free standing.

How to Connect for Seven Channel System Caution: Do not connect the AC Power Cord to the MC8207 Rear Panel until after the Loudspeaker Connections are made and the protective Terminal Connections Cover is installed. Failure to observe this could result in Electric Shock. The connection instructions below, together with the MC8207 Connection Diagram located on the separate folded sheet “Mc1A”, is an example of a typical Multichannel System.
How to Connect for a Seven Channel System Figure 6 Figure 7 Figure 8 9. Place the IMPEDANCE Switch to the position (4 ohm or 8 ohm) to match the impedance of the connected Loudspeakers. In the event that some of the Loudspeakers in the system are different impedance, use the impedance of the Front Loudspeakers. If the Loudspeaker’s impedance is 6 ohms, select the 4 ohms setting. Refer to “General Information” Note 4 on page 3 for additional information.
How to Connect for a Five Channel and Zone B System Caution: Do not connect the AC Power Cord to the MC8207 Rear Panel until after the Loudspeaker Connections are made and the protective Terminal Connections Cover is installed. Failure to observe this could result in Electric Shock. The connection instructions below, together with the MC8207 Connection Diagram located on the separate folded sheet “Mc1B”. Below is an example of a typical Five Channel and Zone B System.
How to Connect for a Five Channel and Zone B System 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. 8. Connect the MC8207 power cord to an active AC outlet. WARNING: Loudspeaker terminals are hazardous live and present a risk of electric shock.

How to Operate How to Operate Power With the POWER Switch set to the OFF/REMOTE Position, the MC8207 will turn On or Off when an A/V Control Center turns On or Off. For manual operation, place the POWER Switch to the ON Position as desired. Refer to figure 9. Notes: 1. There must be a power control connection between the MC8207 and the McIntosh A/V Control Figure 9 Center in order for the remote power turn-on to function. 2.
Technical Description A continuous average power output rating of 200 watts and an output current of greater than 25 amperes per channel, makes this one of the most advanced and powerful amplifiers McIntosh has ever manufactured. Refer to figures 14 and 16. The distortion limits for the MC8207 are no more than 0.005% at rated power output for all frequencies from 20Hz to 20,000Hz. Typical performance at mid frequencies is less than 0.002%.
Technical Description The high efficiency circuit design of the MC8207 contributes to low operating temperatures. More than 2100 square inches of heat sink area occupies almost half of the MC8207’s chassis space and keeps the amplifier operating safely with convection cooling. No fans are needed.

Packing Instructions Packing Instructions In the event it is necessary to repack the equipment for shipment, the equipment must be packed exactly as shown below. It is very important that the four plastic feet are attached to the bottom of the equipment. Four 1/4 - 20x2-1/4 inch screws and washers must be used to fasten the unit securely to the bottom pad and wood skid. This will ensure the proper equipment location on the bottom pad. Failure to do this will result in shipping damage.
