Connection Method
for use outside the
United States and Canada:
Attach the previously prepared bare wire cable ends into
the spade lug connectors and secure the connections. Insert
the spade lug connector or prepared section of the cable
end into the terminal side access hole, and tighten the ter
-
minal cap until the cable is firmly clamped into the termi-
nals so the lugs cannot slip out. Refer to figures 4, 5 & 6.
4. Connect the loudspeaker hookup cable to the output ter-
minals that match the impedance of your loudspeaker,
being careful to observe the correct polarities. Output
impedance connections of 2 ohms, 4 ohms and 8 ohms
are provided. If the impedance of your loudspeaker is
in-between the available connections, use the nearest
lower impedance connection.
WARNING: Loudspeaker terminals are hazardous live
and present a risk of electric shock. For ad-
ditional instruction on making Loudspeaker
Connections contact your McIntosh Dealer
or McIntosh Technical Support.
5. Attach the supplied Terminal Connections Cover with
the four Phillips Head Mounting Screws (10-32 x 1/2
inch) to the Rear Panel of the MC1.2KW Amplifier.
Refer to figures 7a and 7b ( on the next page).
Note: There are six openings on the bottom edge of the
cover to allow the Loudspeaker’s Cable to exit the
MC1.2KW. The Rear Chassis Handle has tapped
screw openings on both sides for securing the cover.
6. Connect the MC1.2KW power cord to an active AC
outlet.
Caution: The supplied AC Power Cord should not be con-
nected to the Rear Panel of the MC1.2KW Amplifier
until after the Loudspeaker Connections have been
made and the supplied protective Terminal Connec-
tions Cover has been installed. Failure to observe
this could result in Electric Shock.
1. For Remote Power Control, connect a power control
cable from the Control Center or Preamplifier Power
Control Out to the MC1.2KW (Amplifier One) POWER
CONTROL IN.
2. Connect a power control cable from MC1.2KW (Ampli-
fier One) POWER CONTROL OUT to the MC1.2KW
(Amplifier Two) POWER CONTROL IN.
3. Connect a cable from the Balanced Output of a McIn-
tosh Preamplifier or Control Center to the MC1.2KW
(Amplifier One) BALANCED INPUT. Place the IN-
PUT MODE Switch in the BALANCED Position.
Note: An optional hookup is to use an unbalanced cable
and place the INPUT MODE Switch in the UNBAL-
ANCED Position.
4. Connect a cable from
the BALANCED
INPUT/OUTPUT of
the MC1.2KW (Am-
plifier One) to the
MC1.2KW (Amplifier Two) BALANCED INPUT.
5. Prepare the Loudspeaker Hookup Cable for attachment
to the MC1.2KW Power Amplifier:
Bare wire cable ends:
Carefully remove sufficient insulation from the cable
ends, refer to figures 1, 2 & 3. If the cable is strand-
ed, carefully twist the strands together as tightly as
possible.
Notes: 1. If desired, the twisted ends can be tinned with
solder to keep the strands together.
2. Banana plugs are for use in the United States
and Canada
only. In
the United
States,
when using
the 8 ohm
loudspeaker
terminals, it is mandatory to use banana plugs
inserted into the top hole of the loudspeaker
terminals in order to comply with safety stan-
dard requirements.
Connection Method for use inside the United States and
Canada only:
Attach the previously prepared bare wire cable ends into
the banana plugs and secure the connections. Insert the
banana plug only into the hole at the top of the terminal.
