Performance Features

Introduction

·

Power Output

The MCC204 consists of four separate power amplifier

channels, each capable of 50 watts into 4 ohm speakers

with less than 0.005% distortion.

·

Four Bridgeable Channels

The MCC204 includes four 50 watt amplifier channels.

Each pair of channels can be set in bridged configuration

for 200 watts output into 4 ohm loudspeakers with less

than 0.01% distortion.

·

High Current Output

A peak output current of 15 amperes ensures that the

MCC204 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 MCC204 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.

Now you can take advantage of traditional McIntosh stan-

dards of excellence in the MCC204 Power Amplifier. Four

50 watt high current output channels will drive any high

quality loudspeaker system to its ultimate performance.

The MCC204 reproduction is sonically transparent and ab-

solutely accurate. The McIntosh Sound is “The Sound of

the Music Itself.”

·

Thermal Protection with Multi-Speed Cooling Fan

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 fan is normally

off. When needed, the fan will automatically switch on,

and speed is increased as needed for additional cooling.

·

Fully Discrete Design

The MCC204 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 MCC204 provides four 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.
