General Information

Caution: The MC1.2KW Amplifier weight is 147 pounds (66.7 kilograms). It requires two or more persons to safely handle when moving the amplifier.

1.The following Connecting Cable is available from the McIn- tosh Parts Department:

Power Control Cable Part No. 170-202

Six foot, 2 conductor shielded, with two 1/8 inch stereo mini phone plugs.

2.For additional connection information, refer to the owner’s manual(s) for any component(s) connected to the MC1.2KW.

3.The MC1.2KW mutes the speaker output for approximately two seconds when first turned on.

4.It is very important that loudspeaker cables of adequate size be used, so that there will be no power loss. The size is speci- fied in Gauge Numbers or AWG, (American Wire Gauge). The smaller the Gauge number, the larger the wire size:

If your loudspeaker cables are 50 feet (38.1m) or less, use at least 14 Gauge.

If your loudspeaker cables are 100 feet (76.2m) or less, use at least 12 Gauge.

5.In the event the MC1.2KW over heats, due to improper ventilation and/or high ambient temperature, the protection circuits will activate. The Front Panel Power Guard LED will continuously indicate ON and the audio will be muted. When the MC1.2KW has returned to a safe operating temperature, normal operation will resume.

6.The MC1.2KW incorporates the very latest in Fully Double Balanced Circuitry. As a result, the Loudspeaker Negative Connections are above chassis ground. Do not combine any connections together, ground them or connect with another MC1.2KW.
