out. Refer to figures 4, 5 & 6.
Banana plug connection:
Insert the banana plug into the hole at the top of the
termi-
nal.
Refer
to fig-
ures
A and
B.
Note: Banana Plugs are for use in the United States
and Canada only.
When making Loudspeaker Connections to the MA7000
refer to Connection Diagram located on the separate folded
sheet “Mc1B”. This an example of a typical audio system,
your system may vary from this, however the actual Loud-
speakers would be connected in a similar manner.
3. 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.
4. Connect the MA7000 Power Cord to a live AC outlet.
Caution: The supplied AC Power Cord should not be
connected to the Rear Panel of the MA7000
Amplifier until after the Loudspeaker Connec-
tions have been made. Failure to observe this
could result in Electric Shock. For additional
instruction on making Loudspeaker Connec-
tions contact your McIntosh Dealer or McIn-
tosh Technical Support.
When connecting Loudspeakers to the MA7000 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:
If your loudspeaker cables are 50 feet (38.1m) or less,
use at least 14 Gauge.
If your loudspeaker cables are 100 feet (76.2m) or less,
use at least 12 Gauge.
1. This McIntosh MA7000 Integrated Amplifier is de-
signed for the connection of a single Loudspeaker per
amplifier channel, 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.
2. 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,
carefully
twist the strands together as tightly as possible.
Note: If desired, the twisted ends can be tinned with
solder to keep the strands together, or attach spade
lug and/or banana connector.
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
