How to Connect the MC126 for Three
Channels
Caution: The supplied AC Power Cord should not be
connected to the Rear Panel of the MC126
Amplifier until after the Loudspeaker Connections
have been made and the supplied protective
Terminal Connection Covers have been installed.
Failure to observe this could result in Electric
Shock.
1. Connect a power control cable from the McIntosh A/V
Control Center Power Control Out to the McIntosh
MC126 POWER CONTROL IN.
2. Connect cables from the Audio Outputs of a McIntosh
A/V Control Center to the MC126 MONO INPUTS.
3. Prepare the Loudspeaker Hookup Cables that attach to
the MC126 Power Amplifier by choosing one of the
methods below:
Bare wire cable ends:
Carefully remove sufficient insulation from the cable
ends, refer to
figures 1, 2 &
3. If the cable
is stranded,
carefully twist
the strands to-
gether as tightly as possible.
Note: If desired, the twisted ends can be tinned with
solder to keep the strands together, or attach spade
lug and/or banana connector.
Spade lug or prepared wire connection:
Insert the spade lug connector or prepared section of
the cable end into the terminal side access hole, and
tighten
the termi-
nal cap
until the
cable is
firmly
clamped
into the terminal so the wires cannot slip out.
Refer to figures 4, 5 & 6.
Banana plug connection:
Insert the banana plug into the hole at the top of the
terminal. Tighten the top portion of the terminal post
and the set screw to secure the banana plug in place.
Note: The use of Banana Plugs s for use in the United
States and Canada only.
5. Connect the Loudspeaker Hookup Cables from the
MC126 MONO OUTPUT Terminals to the loudspeak-
ers, being careful to observe the correct polarities and
channel designation.
WARNING: Loudspeaker terminals are hazardous live
and present a risk of electric shock. For
additional instruction on making
Loudspeaker Connections contact your
McIntosh Dealer or McIntosh Technical
Support.
6. Attach each of the three supplied Terminal Connection
Covers with the four Pan Head
Mounting Screws (6-32 x 5/16
inch) to the Rear Panel of the
MC126 Amplifier. Refer to fig-
ures 7 and 8.
