Performance Features
Introduction
Now you can take advantage of traditional McIntosh stan-
dards of excellence in the MCC301M Power Amplifier. A
300 watt high current output will drive any high quality
loudspeaker to its ultimate performance. The MCC301M
reproduction is sonically transparent and absolutely accu-
rate. The McIntosh Sound is The Sound of the Music It-
self.
· Power Output
The MCC301M consists of a power amplifier capable of
300 watts into 4 ohm speakers with less than 0.005% dis-
tortion.
· High Current Output
A peak output current of 50 amperes ensures that the
MCC301M will successfully drive high quality loudspeak-
ers, such as McIntosh, for a truly exciting sound experi-
ence.
· 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. 24dB per octave low pass filter with vari-
able corner frequencies from 40Hz to 120Hz.
· Subsonic Filter
The selectable frequency Subsonic Filter prevents the am-
plifier circuitry 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 loud-
speakers. 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 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 MCC301M has a fully complimentary double bal-
anced amplifier design and is identical to that found in
McIntoshs 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 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 ex-
ternal 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.
