How To Operate The Mpc1500 - McIntosh MPC1500 Owner's Manual

How to Operate
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- OUTLETS
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

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
