McIntosh MCC302M owner manual Introduction, Performance Features

Introduction

Now you can take advantage of traditional McIntosh stan- dards of excellence in the MCC302 Power Amplifier. Two 150 watt high current output channels will drive any high quality loudspeaker system to its ultimate performance.

The MCC302 reproduction is sonically transparent and ab- solutely accurate. The McIntosh Sound is “The Sound of the Music Itself.”

Performance Features

•Power Output

The MCC302 consists of two separate power amplifier channels, each capable of 150 watts into 4 ohm speakers with less than 0.005% distortion.

•Bridgeable Channels

The MCC302 includes two 150 watt amplifier channels. Both channels can be set in bridged configuration for 600 watts output into a 4 ohm loudspeaker with less than 0.008% distortion.

•High Current Output

A peak output current of 30 amperes ensures that the MCC302 will successfully drive high quality loudspeakers, such as McIntosh, for a truly exciting sound experience.

•Equalizer and Variable Crossover Filters

The one band equalizer has a center frequency that is vari- able from 40 Hz to 2,000 Hz which can be either cut or boosted ±12db. 12dB per octave high pass filters with vari- able corner frequencies from 50Hz to 120Hz and 12dB per octave low pass filters with variable corner frequencies from 50Hz to 120Hz.

•Power Guard and Sentry Monitor

All 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. McIntosh Sentry Monitor power output stage protection circuits are present on all channels to ensure the MCC302 will have a long and trouble free operating life.

•Speaker Protection

If for any reason, a DC (Direct Current) voltage appears at the speaker output terminals, a built-in circuit turns off the amplifier power supplies to prevent damage to your valu- able loudspeakers.

•Thermal Protection with Multi-Speed Cooling Fans Built-in thermal protection circuits guard against overheat- ing which could shorten the normal long life expectancy of your McIntosh Power Amplifier. Cooling fan speed is con- trolled by temperature sensors attached to the interior of the extruded aluminum cooling tunnel. The fans are nor- mally off. When needed, the fans will automatically switch on, and speed is increased as needed for additional cooling.

•Fully Discrete Design

The MCC302 has a fully complimentary double balanced amplifier design and is identical to that found in McIntosh’s leading home amplifiers.

•Balanced Inputs with Pass Through

The Balanced Inputs cancel out interference noise that is produced by other sources in the vehicle and can be di- rectly connected to the bridged speaker output of any head unit. The MCC302 provides two line level outputs, for the convenience of connecting multi-amplifier systems.

•Remote Subwoofer Control and Line Output

The subwoofer level can be controlled via an external ro- tary control, which can be remotely mounted in the vehicle. A line level summed output is provided to drive an external subwoofer power amplifier. The inputs to both channels are summed for this output.

•Gold Plated Terminals

McIntosh provides gold plated input and output terminals on the amplifiers for superior corrosion resistance. It is a very important feature in the automotive environment.

Speaker wires to 10 AWG and DC input wires to 4 AWG can be accommodated.
