1. Prepare the Loudspeaker Hookup Cable for attach-
ment to the MXA80:
Bare wire cable ends:
Carefully remove sufficient insulation from
the cable ends, refer to figures F, G & H. If the
cable is stranded,
carefully twist the
strands together as
tightly as possible.
Notes: 1. If desired, the twisted ends can be tinned
with solder to keep the strands together.
2. The prepared bare wire cable ends may be
inserted into spade lug connectors.
3. Banana plugs are for use in the United
States and Canada only.

into the banana plugs and secure the connections.
Refer to figure I.
Connecting Components
The MXA80 has the ability to automatically switch
power On/Off to McIntosh Source Components via
the Power Control connection.
The connection instructions below, together with
the MXA80 Connection Diagram on the next page
is an example of a typical audio system. Your system
may vary from this, however the actual components
would be connected in a similar manner. For addition-
al information refer to “Connector and Cable Informa-
tion” on page 4.
Note: When the MXA80 is being added to an existing
Audio (or Audio/Video) System, please proceed to
page 12. If the MXA80 will be used with an external
Power Amplifier, please refer to page 13.
