1. For additional connection information, refer to the
owner’s manual(s) for any component(s) connected to
the MPC1500 Power Controller.
2. The Main AC Power going to the MPC1500 and any
other McIntosh Component(s) should not be applied
until all the system components are connected together.
Failure to do so could result in malfunctioning of some
or all of the system’s normal operations.
3. In the event the MPC1500 Power Controller overheats
due to improper ventilation and/or high ambient tem-
perature, the Power Controller will switch off. When
the MPC1500 has returned to a safe operating tempera-
ture, normal operation will resume.
4. The MPC1500 is designed for connection of Audio/
Video Components with low energy consumption.
This would include components such as Preamplifiers,
A/V Control Centers, Source Components, Integrated
Amplifiers and Power Amplifiers with low to modest
power output.
The total amount of current drawn by all the compo-
nents connected to the MPC1500 should not exceed 11.2
Amps. Typically, components consuming low amounts
of energy are rated in watts. To calculate the total
energy consumed, it is usually easier to convert compo-
nents rated in Watts to a current rating and then add up
the total current consumed. To convert a wattage rating
into an approximate current rating take the watts rating
and divide it by 100. For example, if a component has a
rating of 65 watts divide it by 100, this would provide
an approximate rating of 0.65 Amps.

Connector Information, Introduction and Performance Features
Connector and Cable Information
Introduction
Performance Features
• Toroidal Isolation Power Transformer
The very large Toroidal Isolation Power Transformer
used in the MPC1500 occupies over three quarters of the
internal space in the chassis. It ensures stable noise free
operation for the audio/video components connected to the
MPC1500. It also isolates them from potential interference
produced from common household appliances that utilize
motors, compressors and electronic control devices.
• Stable Voltage
The MPC1500’s Large Isolation Power Transformer mini-
mizes variations in the voltage available to the connected
components as they draw more current, up to the 11.2 Amp
rating.
• Lono Technology
The LONOTM (Low Noise) Transformer Technology from
Plitron used in the MPC1500, eliminates audible noise
Now you can add to your system the advantage of tradi-
tional McIntosh standards of excellence in the MPC1500
Power Controller. It offers full transformer isolation from
the incoming AC Line for the components connected to it.
The MPC1500 helps to assure the sound and video repro-
duction from your McIntosh System is the best it can be,
totally transparent and absolutely accurate.
Power Control Connector
The MPC1500 Global Power Control Input and Local
Power Control Inputs receive On/Off signals from +5 to
+12 volts. The Global Power Control Output will provide
a +12 volt Output Signal with a current up to 20mA. The
Local Power Control Outputs will
in turn provide from +5 to +12 volt
Output Signal (Input Signal De-
pended). The Global Power Control
Input has an additional connection
for controlling the illumination of
the MPC1500 Voltage and Current Output Meters. The 1/8
inch stereo mini phone plug connects to a Preamplifier or
an 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

emanating from the Transformer and thus will not dis-
tract from musical enjoyment, even with varying AC Line
conditions.
• Superior Line Surge Protection
The McIntosh MPC1500 utilizes the finest, most sophis-
ticated surge suppression technology available. Unlike
most of the AC Line Surge protection devices available,
the MPC1500 doesn’t rely on commonly used inexpensive
MOV devices. The MOV’s can fail after just one surge thus
no longer providing protection and they can allow as much
as 300 volts through to the connected components allow-
ing substantial damage to occur. The MPC1500 incorpo-
rates TorusTM Surge Suppression Circuitry, which activates
around 2V above peak nominal voltage providing constant
long term protection.
• Illuminated Voltage and Current Meters
The Illuminated Voltage and Current Meters indicate at all
times the voltage available to your McIntosh Components
and the actual current consumed by them.
• Power Control
The Power Control Input connection provides convenient
Turn-On/Off of the McIntosh MPC1500 with your McIn-
tosh System.
• Extruded Side Panels
The sides of the MPC1500 are extruded aluminum panels
with a bead blast textured surface and a black anodized
finish.
• Fiber Optic Solid State Front Panel Illumination
The even Illumination of the Front Panel is accomplished
by the combination of custom designed Fiber Optic Light
Diffusers and extra long life Light Emitting Diodes
(LEDs). The glass Front Panel ensures the pristine beauty
of the MPC1500 will be retained for many years.

Installation
Installation
The MPC1500 can be placed upright on a table or shelf,
standing on its four feet. It also can be custom installed in
a piece of furniture or cabinet of your choice. The four feet
may be removed from the bottom of the MPC1500 when it
is custom installed as outlined below. The four feet togeth-
er with the mounting screws should be retained for possible
future use if the MPC1500 is removed from the custom
installation and used free standing. The required panel
cutout, ventilation cutout and unit dimensions are shown.
Always provide adequate ventilation for your MPC1500.
Cool operation en-
sures the longest pos-
sible operating life for
any electronic instru-
ment. Do not install
the MPC1500 directly
above a heat generat-
ing component such as
a high powered ampli-
fier. If all the compo-
nents are installed in a
single cabinet, a quiet
running ventilation
fan can be a definite
asset in maintaining
all the system com-
ponents at the coolest
possible operating
temperature.
A custom cabinet
installation should
provide the follow-
ing minimum spacing
dimensions for cool
operation.
Allow at least 4 inches
(10.16cm) above the
top, 2 inches (5.08cm)
below the bottom and 1 inch (2.54cm) on each side of the
Power Controller, so that airflow is not obstructed. Allow
20 inches (50.8cm) depth behind the front panel. Allow 2
inches (5.08cm) in front of the mounting panel for knobs.
Be sure to cut out a ventilation hole in the mounting shelf
according to the dimensions in the drawing.

Meter reading starts to drop more than several volts (from
the nominal voltage reading at lower current consumption)
when the MPC1500 AMPERES Meter indicates 6 Amps
of current or greater, it may be an indication of a condition
known as “AC Line Sag”. AC Line Sag is usually a result
of limitations in the AC Wiring in the walls due to small
wire size and/or long lengths of wire. For additional as-
sistance in this matter contact your McIntosh Dealer and/or
Electrical Contractor.
Current Meter
The AMPERES Meter indicates the total amount of cur-
rent being consumed by the components connected to the
MPC1500 AC Outlets. Refer to figure 4. It is normal for
the AMPERES Meter indication to fluctuate especially
when a Power Amplifier or Integrated Amplifier is con-
nected to the MPC1500 AC Outlets and music is being
played loudly.
Rear Panel Options
AC Outlets number 3 thru 6 can be individually config-
ured to become active via three different methods using
the Rear Panel Switches. The first way is using the default
configuration (the switch in the GLB position) where the
outlet is controlled to switch On or Off via the MPC1500
Global Power Control Input or the Front Panel Power Con-
trol Switch. Refer to figure 5 on the next page. The second
option is to have any one of the AC Outlets (number 3
thru 6) controlled independently On/Off via the MPC1500
Local Power Control Input for each outlet by placing the
The MPC1500 Power Controller is very versatile in its con-
nection and operation in an Audio, Video or Audio/Video
System. There are two examples of connecting and using
the MPC1500 on pages 8 and 9 of this Owner’s Manual.
By becoming familiar with the “How to Operate” section
of this Owner’s Manual many additional connection and
operation possibilities will become apparent.
Power Control
To have the MPC1500 automatically turn On or Off when a
Preamplifier or A/V Control Center turns on or off, rotate
the POWER CONTROL Switch to the REMOTE posi-
tion. For manual operation, rotate the POWER CONTROL
Switch to the ON or OFF position as
desired. Refer to figure 1.
Notes: 1. There must be a power con-
trol connection between the
MPC1500 Global Power Con-
trol Input and the Preamplifier
or A/V Control Center, in order
for the remote power turn-on to
function.
2. When the POWER CONTROL Switch is placed
in the ON the position, the Global Power Control
Input activation is overridden.
3. AC Outlets 3 thru 6 switch On in sequence with a
slight delay in time between each outlet activation.
Meter Illumination
Rotate the METER LIGHTS Switch to select the meter
operation mode you desire. Refer to
figure 2.
OFF - Meter lights are switched Off.
Note: The meters will
continue to indicate
the Input AC Line
Voltage and the con-
sumed Current.
AUTO - Meter lights are switched
On. When Global Power Control Input of the
MPC1500 is connected to a McIntosh Preampli-
fier or A/V Control Center with Remote Meter
Illumination Control, the Meter Illumination
will be remotely controlled (On/Off).
Volt Meter
The VOLTS Meter indicates the AC Voltage available at
the AC Outlets on the MPC1500 Rear Panel. Refer to fig-
ure 3. The MPC1500 utilizes a very large isolation power
transformer, so essentially the VOLTS Meter reading is a
reflection of the incoming AC Line Voltage. If the VOLTS
