General Information
1. The MI502 mutes the speaker output for approxi-
mately two seconds when rst turned on.
2. Included with the MI502 are two Side Rack
Mounted Brackets and screw fasteners. Refer to
page 5 for installing the Side Rack Mount Brackets.
3. For the best performance and safety it is important
to always attach a single Loudspeaker with an 8
Ohm or 4 Ohm impedance to the Right or Left
Channel output terminals. Refer to “How to
Connect” on page 8.
Note: The impedance of a Loudspeaker actually varies as
the Loudspeaker reproduces different frequencies.
As a result, the nominal impedance rating of the
Loudspeaker (usually measured at a midrange
frequency) might not always agree with the imped-
ance of the Loudspeaker at low frequencies where
the greatest amount of power is required. Contact the
Loudspeaker Manufacturer for additional informa-
tion about the actual impedance of the Loudspeaker
before connecting it to the McIntosh MI502.
4. In the event the MI502 Channel(s) over heat, due to
improper ventilation or Loudspeaker Impedance,
the protection circuits will activate. The Front
Panel Channel LED will change color and the audio
will be muted. Refer to page 9. When the MI502
has returned to a safe operating temperature,
Channel(s) normal operation will resume.
5. For additional information on the MI502 and
other McIntosh Products please visit the McIntosh

Introduction
Now you can take advantage of traditional
McIntosh standards of excellence in the MI502
Power Amplier. The Two Channel Power Amplier
produces high power output per channel and will
drive quality Loudspeakers to a high level of
performance. The MI502 reproduction is sonically
transparent and absolutely accurate. The McIntosh
Sound is “The Sound of the Music Itself.”

Connector and Cable Information
XLR Connectors
Below is the Pin conguration for the XLR
Balanced Input, Input/Output Connectors on the
MI502. Refer to the diagram for connection:
PIN 1: Shield/Ground
PIN 2: + Input/Output
PIN 3: - Input/Output
Power Control Connector
The MI502 Power Control Input receives an
On/O signal from +5 to +12 volts. The Power
Control Output will in turn
provide a +12 volt Output Signal
with a total current up to 50mA.
An additional connection is for
controlling the illumination of
the MI502 Meter Power Output Indicators. The
3.5mm stereo mini phone plug connects to a
McIntosh Preamplier or A/V Control Center
Power Control Output.
Output Terminal Connector
When cables with spade lugs are
used for Loudspeaker Connection,
the spade lugs need an opening of at
least 3/10 inch (7.6mm)

• Power Output
The MI502 consists of Two Power Amplier
Channels, each capable of 500 watts into 8
ohms 800 watts into 4 ohms Loudspeakers with
distortion less than 0.05%.
• Loudspeaker Guard
The McIntosh Loudspeaker Guard Circuit
prevents the amplier from being over driven
into clipping, with its harsh distorted sound that
can damage your valuable Loudspeakers.
• Balanced and Unbalanced Inputs
There are Balanced and Unbalanced
Connections for both Power Amplier Input
Channels.
• Sentry Monitor and Thermal Protection
McIntosh Sentry Monitor power output stage
protection circuits ensure the MI502 will have
a long and trouble free operating life. Built-in
Thermal Protection circuits guard against
overheating.
• Illuminated Power Meters
The Illuminated Power Output Watt Meters on
the MI502 are peak responding, and indicates
the Power Output of the ampliers.
• Power Control
The McIntosh Power Control Circuit allows for
remote turn-on of the MI502 Power Amplier
from a McIntosh A/V Control Center or
Preamplier for a single or dual Zone System.
• Special Power Supply
A regulated Power Supply ensures stable
noise free operation even though the power line
varies.
• LED Solid State Front Panel Illumination
The even Illumination of the Front Panel is
accomplished by extra long life Light Emitting
Diodes (LEDs). The Metal and Glass Front
Panel ensures the pristine beauty of the MI502
will be retained for many years.
