How to Connect
Connecting Loudspeakers
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

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
WARNING: Loudspeaker terminals are hazardous live and present a risk of electric shock.
4.Connect the MA7000 Power Cord to a live AC outlet.
