7. Referring to figure H, connect the Loudspeaker
hookup cables with
banana plugs into the
MC255 hole at the top
of the terminal to the
Negative Output Termi-
nal and the Positive Output Terminal indenti-
fied as 4Ω (ohm) or 8Ω (ohm) connection to match
the impedance of the Loudspeaker, being careful
to observe the correct polarities. Place the LOAD
Switch on the rear panel of the MC255 to either
the 4 or 8 Ohm Setting, to match the impedance of
the majority of the loudspeakers connected.
If the Loudspeaker’s impedance is in-between the
available connections, use the nearest lower im-
pedance 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.
8. Connect the MC255 power cord to an active AC
outlet.
Spade Lug or Wire Connections:
9. Connect the Loudspeaker hookup cables to the
MC255 COM (Negative) Output Terminal and
Positive Output Terminal indentified as 4Ω (ohm)
or 8Ω (ohm) 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.
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

tact your McIntosh Dealer or McIn-
tosh Technical Support.
10. Connect the MC255 power cord to an active AC
outlet.
