McIntosh MCC301M

Category: Mcintosh
Product Code: MCC301M

 The MCC301M consists of a power amplifier capable of 300 watts into 4 ohm speakers with less than 0.005% distortion.

A peak output current of 50 amperes ensures that the MCC301M will successfully drive high quality loudspeakers, such as McIntosh, for a truly exciting sound experience.

MCC301M Power Amplifier Features

Equalizer and Variable Crossover Filters
The one band equalizer has a center frequency that is variable from 40 Hz to 2,000 Hz which can be either cut or boosted ±12db. 24dB per octave low pass filter with variable corner frequencies from 40Hz to 120Hz.

Subsonic Filter
The selectable frequency Subsonic Filter prevents the amplifier ircuitry from amplifying non audible signals and thus wasting amplifier power.

Power Guard and Sentry Monitor
The Patented McIntosh Power Guard Circuit 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 circuit is present to ensure the MCC301M 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 valuable loudspeakers.

Thermal Protection with Multi-Speed Cooling Fans
Built-in thermal protection circuits guard against overheating which could shorten the normal long life expectancy of your McIntosh Power Amplifier. Cooling fan speed is controlled by temperature sensors attached to the interior of the extruded aluminum cooling tunnel. The fans are normally off. When needed, the fans will automatically switch on, and speed is increased as needed for additional cooling.

Fully Discrete Design
The MCC301M 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 directly connected to the bridged speaker output of any head unit. The MCC301M provides two line level outputs, for the convenience of connecting multi-amplifier systems.

Illuminated Power Meter
The Illuminated Power Output Watt Meter on the MCC301M is peak responding and almost ten times faster than a professional VU meter. It also indicates the true power output of the amplifier regardless of the loudspeaker impedance, as both the voltage and current are measured.

Remote Subwoofer Control and Line Output
The subwoofer level can be controlled via an optional external rotary control, which can be remotely mounted in the vehicle. A line level output is provided to drive an external subwoofer power amplifier.

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.
