McIntosh MC 2500 Owners Manual

VARIOUS REGULATORY AGENCIES REQUIRE THAT WE BRING THE FOLLOWING INFORMATION TO YOUR ATTENTION. PLEASE READ IT CAREFULLY. The Mclntosh MC 2500 is an ex­ tremely high power amplifier. Because of the high power available it is necessary to emphasize some prudent and safe operating condi­ tions. 1. Loudspeakers can be damaged or destroyed by the high power available from the MC 2500. Never connect or disconnect inputs or outputs while the amplifier is turn­ ed on. 2. Never operate the amplifier with the power cord plugged into an auxiliary AC power outlet on source equipment. The amplifier draws 15 amperes and can damage the source equipment. 3. Do not operate the instrument plug­ ged into an ordinary extension cord. A heavy duty extension cord (14 ga. or heavier) is required. 4. Be cautious when lifting the instru­ ment. It weighs 129 pounds. Make certain that what it is placed on can support the weight. 5. The amplifier cooling fans can be thermostatically controlled when the fan switch on the rear panel is placed in the thermally switched positions. When so operated, the fans will not run when the amplifier is cool, as when the amplifier is first turned on. As heat develops, one or both fans will automatically turn on as conditions require. This operating behavior is normal. WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE. The Mclntosh you have purchased is a Model MC 2500.
