Spade lug or prepared wire connection:
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
terminal so the
wires cannot slip
out. Refer to fig-
ures 4, 5 & 6.
Banana plug connection:
Insert the banana plug into the hole at the top of the
terminal. Refer to figures A and B.
Note: Banana
Plugs are
for use in
the United
States and
Canada
only.
When making Loudspeaker Connections to the MC2301
refer to the Connection Diagram on the next page. This
is an example of a typical audio system, your system may
vary from this, however the actual Loudspeaker would be
connected in a similar manner.
5. Connect the Loudspeaker hookup cables from a single
Loudspeaker to the output terminals that match the im-
pedance of the Loudspeaker, being careful to observe
the correct polarities. Output impedance connections
of 2 ohms, 4 ohms and 8 ohms are provided. If the
Loudspeaker’s impedance is in-between the available
connections, use the nearest lower impedance connec-
tion.
WARNING: Loudspeaker terminals are hazardous live
and present a risk of electric shock.
6. Connect the MC2301 Power Cord to a live AC outlet.
Caution: The supplied AC Power Cord should not be
connected to the Rear Panel of the MC2301
Tube Power Amplifier until after the Loud-
speaker Connections have been made. Failure
to observe this could result in Electric Shock.
For additional instruction on making Loud-
speaker Connections contact your McIntosh
Dealer or McIntosh Technical Support.
1. For Remote Power Control, connect a power control
cable from the Control Center or Preamplifier Power
Control Out to the MC2301 POWER CONTROL IN.
2. Connect a cable from the Balanced Output of a Mc-
Intosh Preamplifier or Control Center to the MC2301
BALANCED INPUT. Place the INPUT MODE Switch
in the BALANCED Position.
Note: An optional hookup is to use an unbalanced cable
and place the INPUT MODE Switch in the UNBAL-
ANCED Position.
When connecting Loudspeakers to the MC2301 it is very
important to use cables of adequate size, so there is little to
no power loss in the cables. The size is specified in Gauge
Numbers or AWG (American Wire Gauge). The smaller
the Gauge number, the larger the wire size:
3. This McIntosh MC2301 Tube Power Amplifier is de-
signed for the connection of a single Loudspeaker with
an impedance of 2 ohms, 4 ohms or 8 ohms.
Note: The remaining Loudspeaker Terminals on the
Amplifier should not be connected to another
Loudspeaker.
4. Prepare the Loudspeaker Hookup Cables that attach to
the Amplifier by choosing one of the methods below:
Bare wire cable ends:
Carefully remove sufficient insulation from the
cable ends, refer to figures 1, 2 & 3. If the cable is
stranded, care-
fully twist the
strands together
as tightly as pos-
sible.
Note: If desired,
the twisted ends can be tinned with solder to keep
the strands together, or attach spade lug and/or
banana connector.
