Installation 17-1/16" Installation The MC205 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 MC205 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 MC205 is removed from the custom installation and used free standing.
Rear Panel Connections and Switch OUTPUT Connections for a 4 ohm or 8 ohm Loudspeaker for Channel 2 (Left Surround) or ZONE B Left Channel OUTPUT Connections for a 4 ohm or 8 ohm Loudspeaker for Channel 5 (Right Front) Selects the impedance (4 or 8 ohms) of the Loudspeakers connected to the MC205 POWER CONTROL ZA receives turn On/ Off signals from a McIntosh component for Zone A (Channels 1- 5). ZB receives turn On/Off signals from a McIntosh component for Zone B (Channels 2 and 4).
How to Connect for a Five Channel System Caution: Do not connect the AC Power Cord to the MC205 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 MC205 Connection Diagram located on the separate folded sheet “Mc1A”, is an example of a typical Multichannel System.

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 (or Seven Channel System) Caution: Do not connect the AC Power Cord to the MC205 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 MC205 Connection Diagram located on the separate folded sheet “Mc1B”.

How to Operate How to Operate Power With the POWER Switch set to the OFF/REMOTE Position, the MC205 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. Note: There must be a power control connection between the MC205 and the McIntosh A/V Control Center in Figure 9 order for the remote power turn-on to function.
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 15. The distortion limits for the MC205 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 Input Test Signal overdriven amplifier can produce both audible and inaudible distortion levels exceeding 40%. The audible distortion is unpleasant to hear, but the inaudible ultrasonic distortion is also undesirable, since it can damage valuable Loudspeaker System Figure 17 tweeters. You will never experience the harsh Without Power Guard and damaging distortion due to clipping. The Power Guard circuit is a waveform comparator, monitoring both the input and output waveforms.

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 - 20 x 2-1/2 inch screws and washers must be used to fasten the unit securely to the bottom pad and shipping skid. This will ensure the proper equipment location on the bottom pad. Failure to do this will result in shipping damage.
