impedance of the Loudspeaker, being careful to
observe the correct polarities. Insert the spade
lug connector or prepared section of the cable end
into the terminal side access hole, and tighten the
terminal cap until the cable is firmly clamped into
the terminals so the lugs or wire cannot slip out.
Refer to figures 7 and 8.
Note: The illustration on separate sheet “Mc1B”is
connections for 8Ω (ohms) Loudspeakers.
If the Loudspeaker’s impedance is in-between
the available connections, use the nearest lower
impedance connection. Refer to “General Informa-
tion” Note 3 on page 2 for additional information.
WARNING: Loudspeaker terminals are hazard-
ous live and present a risk of electric
shock. For additional instruction on
making Loudspeaker Connections con-
tact your McIntosh Dealer or McIn-
tosh Technical Support.
11. Connect the MC312 power cord to an active AC
outlet.
7. Rotate the top of the Output Terminal
Post clockwise until it is nger tight.
Refer to gure G. Then using the Mc-
Intosh Wrench, rotate the top of the
Output Terminal one quarter of a turn
(90° ). Do not over tighten. Refer to
gure E on page 9.
8. Referring to figure H,
connect the Loudspeaker
hookup cables with ba-
nana plugs into the hole at
the top of the terminal to the MC312 COM (Nega-
tive) Output Terminal and Positive Output Ter-
minal indentified as 2Ω (ohms), 4Ω (ohms) or 8Ω
(ohms) connection to match the impedance of the
Loudspeaker, being careful to observe the correct
polarities.
Note: The illustration on separate sheet “Mc1B”is
connections for 8Ω (ohms) Loudspeakers.
If the Loudspeaker’s impedance is in-between the
available connections, use the nearest lower imped-
ance connection. Refer to “General Information”
Note 3 on page 2 for additional information.
