Note: 1. If desired, the twisted
ends can be soldered to keep the strands together.
2. The prepared bare wire cable ends may also be
inserted into spade lug connectors.

sure to match up channel designation
with Loudspeaker location.

7. Connect the Loudspeaker hookup cables to the
MI502 Output Terminal being careful to observe
the correct polarities, making sure to match up
channel designation with Loudspeaker location.
8. Insert the spade lug connector or prepared
section of the cable end into the terminal side
access hole. Then tighten the terminal cap until
so the lugs or wire cannot slip out. Refer to
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 Technical
Support.
9. Connect the MI502 power cord to an active AC
outlet.

Caution: Do not connect the AC Power Cord
to the MI502 Rear Panel until after the
Loudspeaker Connections are made. Failure
to observe this could result in Electric Shock.
The connection instructions below, provide an
example of a typical Multi-channel System. Your
system may vary from this, however the actual
components would be connected in a similar man-
ner. For additional information refer to “Connec-
tor and Cable Information” on page 3.

between the MI502 and an A/V Control Center
or pre-amplifier, the AUTO OFF Signal Sensing
Circuitry is automatically disabled.

designed for Loudspeakers with an impedance of
4 ohms or 8 ohms. Connect a single Loudspeaker
only to the Channel Output Terminals.
When connecting Loudspeakers to the MI502 it
is very important to use cables of adequate size,
so there is little to no power loss in the cables.
