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.
·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
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 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.
