General Notes

Caution: The MC602 Amplifier weight is 155 pounds (70.31 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 MC602.

3.The MC602 mutes the speaker outputs 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 MC602: PIN 1: Shield or ground

PIN 2: + input PIN 3: - input

6.In the event that the MC602 over heats, due to improper ventilation and/or high ambient temperature, the protection circuits will activate. The Front Panel Power Guard LEDs will continuously indicate ON and the audio will be muted. When the MC602 has returned to a safe operating temperature, normal operation will resume.

7.The MC602 incorporates the very latest in Fully Double

Balanced Circuitry. As a result, the Loudspeaker Negative Connections are above chassis ground and are not common between channels. Do not combine any connections together or ground them.

Introduction

Now you can take advantage of traditional McIntosh standards of excellence in the MC602 Power Amplifier. Two 600 watt high current output channels will drive any high quality loudspeaker system to its ultimate performance. The MC602 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is “The Sound of the Music Itself.”

Performance Features

· Power Output

The MC602 consists of two separate power amplifier channels, each capable of 600 watts into 2, 4 or 8 ohm speakers with less than 0.005% distortion.

· Full Balanced Circuity

The MC602 is fully balanced from inputs to outputs. Each channel 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

Both channels include 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 MC602 will have a long and trouble free operating life. Built-in Thermal Protection Circuits guard against overheating.

·Patented Autoformers

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 loudspeakers.

· Illuminated Power Meters

The Illuminated Power Output Watt Meters on the MC602 are peak responding, and indicate the true power output of the amplifier. The Peak Watt Hold Mode allows the meters to temporarily stay at the highest power output and then slowly decay.
