SPEAKER AND SUBWOOFER CONNECTIONS

Diagram 6 shows a typical application for connecting a pair of speakers to the M40 Speaker A Terminals and, if used, typical con-
nections for adding an optional subwoofer to the Sub Out A.
Note: Do not connect more than one pair of 4Ω speakers directly to the M40. Do not connect more than one pair of 8Ω speakers
directly to the Speaker A and B Terminals at the same time. This will cause the M40 to shut down and can damage the unit. This
type of damage is not covered by the Warranty.
To connect multiple speaker pair to the M40, see Page 18.
Speaker A Connections
1. Use 16AWG (min) 2-conductor stranded speaker wire for speaker connection. (Refer to the Speaker Wire Length Chart on Page
18 for wire runs over 150' . )
2. Strip approximately 1/2 to 3/4 of an inch off the ends and twist the strands together so there are no loose ends that can cause
shorts.
3. Loosen the Speaker A Terminals as shown in Diagram 7 so there is enough room between the post and the collar to feed the
striped wire through without damaging the strands.
4. Tighten the post to secure the wire.
5. Repeat for all Speaker A Left and Right, + and –.
6. Confirm connection and polarity.
7. Connect the speaker wires to the appropriate left and right + and – terminals on the speakers.
8. Confirm connection and polarity.
