Introduction

• Power Guard

The patented McIntosh Power Guard circuit prevents the amplifier from being over driven into clipping, with its harsh distorted sound that can also damage your valuable loudspeakers.

• Sentry Monitor and Thermal Protection

McIntosh Sentry Monitor power output stage protection circuits ensure the MC1.2KW will have a long and trouble free operating life. Built-in Thermal Protection Circuits guard against overheating.

• Patented Autoformer

McIntosh designed and manufactured Output Autoformers provide an ideal match between the amplifier output stages and speaker loads of 2, 4 and 8 ohms. The Autoformers also provide perfect DC protection for your valuable loud- speakers.

• Special Power Supply

A regulated Power Supply, a very large Toroidal Wound Power Transformer and very large capacitors ensures sta- ble noise free operation even though the power line varies.

Now you can take advantage of traditional McIntosh standards of excellence in the MC1.2KW Power Ampli- fier. The 1,200 watt high current output will drive any high quality loudspeaker system to its ultimate performance. The MC1.2KW reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is “The Sound of the Music Itself.”

Performance Features

• Power Output

The MC1.2KW is a Power Amplifier with a capability of 1,200 watts into 2, 4 or 8 ohm speakers with less than 0.005% distortion.

• Full Balanced Quad-Differential Circuitry

The MC1.2KW is fully balanced from inputs to outputs. It consists of two matched power amplifiers operating in push-pull with their outputs combined in a McIntosh Auto- former. The double balanced configuration cancels virtu- ally all distortion.

• Balanced and Unbalanced Inputs

Balanced connections guard against induced noise and al- low long cable runs without compromising sound quality.

• Illuminated Power Meter

The Illuminated Power Output Watt Meter on the MC1.2KW is peak responding, and indicates the true power output of the amplifier. The Peak Watt Hold Mode allows the meter to temporarily stay at the highest power output and then slowly decay. The Front Panel Meter Il- lumination may be switched Off at any time.

Fiber Optic Solid State Front Panel Illumination The even Illumination of the Front Panel is accomplished by the combination of custom designed Fiber Optic Light Diffusers and extra long life Light Emitting Diodes (LEDs).

Glass Front Panel and Super Mirror Chassis Finish The famous McIntosh Illuminated Glass Front Panel and the Stainless Steel Chassis with Super Mirror Finish en- sures the pristine beauty of the MC1.2KW will be retained for many years.
