CHAPTER 4: MM-10AC SUBWOOFER
The MM-10AC subwoofer includes an internal power supply
and locking AC PowerCon connectors. The MM-10AC
receives audio from an XLR female Audio In connector, and
also includes an XLR male Audio Loop Out connector for
daisy-chaining audio signals.

MM-10AC AC CONNECTORS
The MM-10AC subwoofer combines advanced loudspeaker
technology with equally advanced power capabilities.
Understanding voltage and current requirements, as well as
electrical safety issues, is critical to the safe operation of the
MM-10AC. The MM-10AC rear user panel includes the fol-
lowing PowerCon AC connectors:

AC Input Connector (Blue)
The blue AC Input connector supplies power to the
MM-10AC. The input is rated at 20 amps and uses a
PowerCon3 AC mains locking connector that prevents acci-
dental disconnections. A 10-foot AC power cable, rated at
15 amps, is included with each MM-10AC. If you replace the
included AC power cable, make sure to use a cable with the
appropriate power plug (on the other end) for the region in
which you will operate the unit.

The AC Input connector also supplies power to any addi-
tional subwoofers connected to the MM-10AC’s gray AC
Loop Output connector. Each MM-10AC requires approxi-
mately 0.9 A rms maximum at 115 V AC and 0.4 A rms max-
imum at 230 V AC.

CAUTION:
When using the included AC power
cable, do not loop more than 15 additional
MM-10ACs from the AC Loop Output connector at
115 V (16 total for the circuit), and not more than 36
at 230 V (37 total for the circuit).

AC Loop Output Connector (Gray)
The gray AC Loop Output connector allows multiple
MM-10AC subwoofers to be looped and powered from a
single power source. Connect the AC Loop Output of the
first MM-10AC to the AC Input of the second MM-10AC,
and so forth. The AC Loop Output uses a PowerCon3 AC
mains locking connector that prevents accidental discon-
nections.

and so forth. The AC Loop Output uses a PowerCon3 AC
mains locking connector that prevents accidental discon-

The maximum number of subwoofers that can be looped
from the AC Loop Output connector is determined by the
voltage of the power source, the current draw of the looped
subwoofers, the circuit breaker rating, and the rating of the
AC power cable connected to the MM-10AC.

subwoofers, the circuit breaker rating, and the rating of the
AC power cable connected to the MM-10AC.
NOTE:
The current draw for the MM-10AC is
dynamic and fluctuates as operating levels
change. The numbers in Table 4 assume that operat-
ing levels are normal and not such that the subwoof-
ers are constantly limiting.
