McIntosh MCC404

Category: Mcintosh
Product Code: MCC404
MCC404 Power Amplifier

The McIntosh MCC404 may not have those famous blue meters under it's glass top plate, but it does have a potent 4-channel amplifier whose high quality construction and jaw dropping performance are pure McIntosh. Rated at 100 watt x 4, 20-20KHz, 0.005%THD, the MCC404 is powered by a highly regulated Pulse Width Modulated power supply. The amps are configurable as either a four, three, or two channel system. Bridging a pair of channel will provide an awesome 400 watts of power, also at 20-20KHz, 0.005%THD.

The fully discrete design has balanced noise canceling inputs and a pass through for use with additional amplifiers. What kind of system would need additional amplifiers with this thing on-line? A built-in variable crossover lets you sort the music out to the various drivers, and selectable high and low pass filters keep the power focused in the appropriate operating ranges. A one-band equalizer with an adjustable center frequency helps to further tune your system.

MCC404 Power Amplifier Features

Power Output
The MCC404 consists of foru separate power amplifier channels, each capable of 100 watts into 4 ohm speakers with less than 0.005% distortion.

4 Bridgeable Channels
The MCC404 includes four 100 watt amplifier channels. Each pair of channels can be set in bridged configuration for 400 watts output into 4 ohm loudspeakers with less than 0.007% distortion.

High Current Output
A peak output current of 20 amperes ensures that the MCC404 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 variable from 40Hz to 2,000Hz that  can be either cut or boosted +/- 12dB. 12dB per octave high pass filters with variable corner frequencies from 5Hz to 5,000Hz and 12dB per octave low pass filters with variable corner frequencies from 50Hz to 5,000Hz.

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 theMCC404 will have a long and trouble free operating life.

Speaker Protection
If for any reason, a DC voltage appears at the speaker output terminal, a built-in circuit turns off the amplifier power supplies to prevent damage to your valuable loudspeakers.
