Below is the Pin configuration for the XLR Balanced
Input, Input/Output Connectors on the MC2301. Refer
to the diagram for connection:

Power Control Connector
The MC2301 Power Control Input receives an On/
Off signal from +5 to +12 volts.
The Power Control Output will
in turn provide a +12 volt Out-
put Signal with a current up to
20mA. An additional connection
is for controlling the illumina-
tion of the MC2301 Power Output Meter. The 1/8 inch
stereo mini phone plug connects to a McIntosh A/V
Control Center Power Control Output.
Note: The Power Control Connecting Cable is available
from the McIntosh Parts Department:
Data and Power Control Cable Part No. 170-202
Six foot, shielded 2 conductor, with 1/8 inch stereo
mini phone plugs on each end.

Now you can take advantage of traditional McIntosh
standards of excellence in the MC2301 Tube Power
Amplifier. The 300 watt power output will drive
any high quality Loudspeaker System to its ultimate
performance. The MC2301 reproduction is sonically
transparent and absolutely accurate. The McIntosh
Sound is “The Sound of the Music Itself.”
• Power Output
The MC2301 is a Tube Power Amplifier with a capa-
bility of 300 watts into 2, 4 or 8 ohm speakers with
less than 0.5% distortion.
• Full Balanced Unity Coupled Circuitry
The MC2301 is fully balanced from input to output. It
consists of two matched Power Amplifiers operating
in push-pull using the famous McIntosh Patented Uni-
ty Coupled Circuit. The circuit outputs are combined
in a dual core McIntosh Multifilar Wound Output
Transformer for low distortion, extended frequency
response and cool operating output tubes.
• Balanced and Unbalanced Input
Balanced connections guard against induced noise and
allow long cable runs without compromising sound
quality.
• Sentry Monitor Tube and Thermal Protection
McIntosh Sentry Monitor Tube Protection Circuits
ensure the MC2301 will have a long and trouble free
operating life. Built-in Thermal Protection Circuits
guard against overheating.
• Illuminated Power Meter
The Illuminated Power Output Watt Meter on the
MC2301 is peak responding, and indicates the true
power output of the amplifier. The Peak Watt Hold
Mode allows the meter to temporarily stay at the high-
est power output and then slowly decay. The Front
Panel Meter Illumination may be switched Off at any
time.
• Gold Plated Connectors and Tube Socket Con
-
tacts
Gold Plated Input Jacks and Output Binding Posts
provide trouble free connections. Ceramic tube sock-
ets with gold plated contacts provide protection from
atmospheric contamination. Output Tube Sockets
include Air-Pipe cooling at their bases.
• Special Power Supply
A regulated Power Supply, a very large core Power
Transformer and large capacitors ensure stable noise
free operation even though the power line varies.
• Fiber Optic Solid State Front Panel Illumination
The even Illumination of the Front Panel is accom-
plished by the combination of custom designed Fiber
Optic Light Diffusers and extra long life Light Emit-
ting Diodes (LEDs).
• Glass Front Panel and Super Mirror Chassis Fin

ish
The famous McIntosh Illuminated Glass Front Panel
and the Stainless Steel Chassis with Super Mirror Fin-
ish ensure the pristine beauty of the MC2301 will be
retained for many years.
