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
making Loudspeaker Connections con-
tact your McIntosh Dealer or McIn-
tosh Technical Support.
10. Connect the MC257 power cord to an active AC
outlet.
7. Referring to figure H, connect the Loudspeaker
hookup cables with
banana plugs into the
MC257 hole at the top
of the terminal to the
( ) Negative Output
Terminal and the ( ) Positive Output Terminal
indentified as 4Ω (ohms) or 8Ω (ohms) 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 MC257 to
either the 4 or 8 Ohm Setting, to match the imped-
ance of the majority of the loudspeakers connected.
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.

9. Connect the Loudspeaker hookup cables to the
MC257 COM (Negative) Output Terminal and
Positive Output Terminal indentified as 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
