13. In a similar manner, connect the other Jumper Bar
between the two (+) Positive 16Ω Output Termi-
nals for connecting a 8Ω (ohm) Loudspeaker (or
between the 8Ω Terminals for a 4Ω (ohm) Loud-
speaker, or between the 4Ω Terminals for a 2Ω
(ohm) Loudspeaker). It is important to match the
impedance of the Loudspeaker, being careful to
observe the correct polarities. If the Loudspeaker’s
impedance is in-between the available connections,
use the nearest lower impedance connection. Refer
to “General Information” Note 3 on page 6 for ad-
ditional information.
14. Connect the Loudspeaker hookup cables to the
MC275 LEFT OUTPUT Negative (-) Terminal and
Positive Output (+) Terminal (which has the previ-
ously installed Jumper Bars).
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. Connect the MC275 Power Cord to an active AC
outlet.
McIntosh 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 MC275 LEFT
OUTPUT Negative
(-) Terminal and the
Positive Output (+) Terminal (which has the previ-
ously installed Jumper Bars).
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. Connect the MC275 Power Cord to an active AC
outlet.
Spade Lug or Wire Connections:
12. For the MC275 MONO Mode of operation, use the
supplied Jumper Bars for connecting the Output of
the Left and Right Amplifier Channels in parallel.
Insert the Jumper Bar into the terminal side access
hole of the LEFT OUTPUT (-) Negative Termi-
nal post and the other end of the Jumper Bar into
the RIGHT OUTPUT (-) Negative Terminal post.
Tighten the terminal caps until the Jumper Bar is
firmly clamped into the terminals so the Jumper
Bar cannot slip out nor touch the chassis. Refer
to Connection Diagram located on the separate
folded sheet “Mc1B”. Also refer to figures 4, 5 and
figure E.
Note: Refer to “Output Terminals” step 4 on
page 12 for important information.
Banana Plugs are for use in the United States and
Canada only:
6. Attach the previously prepared bare wire cable ends
into the banana plugs and secure
the connections. Refer to figure F.
7. For the MC275 MONO Mode of
operation, use the supplied Jumper
Bars to connect the Output of the
Left and Right Amplifier Channels
in parallel.
Insert a Jumper Bar into the terminal side access
hole of the LEFT OUTPUT (-) Negative Termi-
nal post and the other end of the Jumper Bar into
the RIGHT OUTPUT (-) Negative Terminal post.
Tighten the terminal caps until the Jumper Bar is
firmly clamped into the terminals so the Jumper
Bar cannot slip out nor touch the chassis. Refer to
Connection Diagram located on the separate folded
sheet “Mc1B”.
8. In a similar manner, connect the other Jumper Bar

mation.
9. Rotate the top of the Output
Terminal Posts clockwise until
they are all nger tight. Refer
to gure G. Then using the
