How to Connect for Bi-Amp
14. Connect the Loudspeaker hookup cables to the
MC1.25KW Negative Output Terminal and Posi-
tive Output Terminal indentified as 2Ω (ohms),
4Ω (ohms) or 8Ω (ohms) connection to match the
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 in figure 6 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 3 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.
15. Attach the Terminal Connections Cover to the
MC1.25KW Rear Panel with the previously re-
moved Screws. Refer to figure 6.
16. Connect the MC1.25KW power cord to an active
AC outlet.
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 3 for additional information.
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 Techni-
cal Support.
11. Attach the Terminal Connections Cover to the
MC1.25KW Rear Panel with the previously re-
moved Screws. Refer to figure 5.
12. Connect the MC1.25KW power cord to an active
AC outlet.
Spade Lug or Wire Connections:
13. Locate the Terminal Connections Cover from the
inside of the MC1.25KW shipping carton. Insert
the just prepared Loudspeaker hookup cables
thru the cover opening on the right side. Refer to
figure 6.
8. Attach the previously prepared bare wire cable
ends into the banana plugs and secure
the connections. Refer to figure F.
9. 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.
10. Referring to figure H, connect the
Loudspeaker hookup
cables with banana plugs
into the hole at the top of
the MC1.25KW Nega-
tive and Positive Output
Terminals. The terminals
are 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 in figure 5 is connections for
8Ω (ohms) Loudspeakers.
