General Notes

Caution: The MC1201 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 McIntosh 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 MC1201.

3.The MC1201 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 specified 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.Pin configuration for the XLR Balanced Input connectors on the MC1201: PIN 1: Shield or ground

PIN 2: + input

PIN 3: - input

6.In the event that the MC1201 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 MC1201 has returned to a safe operating temperature, normal operation will resume.

7.The MC1201 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 MC1201.

Introduction

Now you can take advantage of traditional McIntosh stan- dards of excellence in the MC1201 Power Amplifier.

Performance Features

·Power Output

The MC1201 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 Circuity

The MC1201 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 Autoformer. The double balanced configuration cancels virtually all distortion.

·Power Guard

The patented McIntosh Power Guard circuit that prevents the amplifier from being overdriven 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 MC1201 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.

·Illuminated Power Meter

The Illuminated Power Output Watt Meter on the MC1201 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.
