CHAPTER 5: MM-10ACX SUBWOOFER
The MM-10ACX subwoofer includes onboard DC power and
audio routing for driving satellite loudspeakers: up to two
MM-4XPs, or a single UP-4XP (due to its higher power
requirements and current draw). Three independent XLR
female Audio In connectors are provided for the subwoofer
and satellite loudspeakers. Satellite Out connectors are
available as either Phoenix 5-pin male or EN3 5-pin female.
The MM-10ACX also includes locking AC PowerCon con-
nectors.
The MM-10ACX is extremely versatile. It can be used as a
standalone subwoofer or it can be connected to and used
with satellite loudspeakers in several different configura-
tions. For more information, see “MM-10ACX Satellite Con-
figurations” on page 34.
MM-10ACX AC CONNECTORS
The MM-10ACX subwoofer combines advanced loud-
speaker technology with equally advanced power capabili-
ties. Understanding voltage and current requirements, as
well as electrical safety issues, is critical to the safe opera-
tion of the MM-10ACX. The MM-10ACX rear user panel
includes the following PowerCon AC connectors:
AC Input Connector (Blue)
The blue AC Input connector supplies power to the
MM-10ACX. 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-10ACX. 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-10ACX’s gray AC
Loop Output connector, as well as any loudspeakers con-
nected to the Satellite Out connectors. Each MM-10ACX
requires approximately 3 A rms maximum at 115 V AC and
1.5 A rms maximum at 230 V AC.
CAUTION: When using the included AC power
cable, do not loop more than five additional
MM-10ACXs from the AC Loop Output connector at
115 V (six total for the circuit), and not more than 10
at 230 V (11 total for the circuit).
