AC Loop Output Connector (Gray)
The gray AC Loop Output connector allows multiple
MM-10ACX subwoofers to be looped and powered from a
single power source. Connect the AC Loop Output of the
first MM-10ACX to the AC Input of the second MM-10ACX,
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

nections.
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 and any connected satellite loudspeakers, the
circuit breaker rating, and the rating of the AC power cable
connected to the MM-10ACX.

voltage of the power source, the current draw of the looped
subwoofers and any connected satellite loudspeakers, the
circuit breaker rating, and the rating of the AC power cable
connected to the MM-10ACX.
NOTE:
The current draw for the MM-10ACX is
dynamic and fluctuates as operating levels
change. The numbers in Table 5 assume that operat-
ing levels are normal and not such that the subwoof-
ers and satellite loudspeakers are constantly limiting.

Each MM-10ACX ships with one AC looping connector for
making AC looping cables. Assembled AC looping cables

CAUTION:
Do not exceed the current capabil-
ity of the 20-amp Input connector for the
MM-10ACX. When looping MM-10ACXs, consider
the total current draw for all subwoofers and satellite
loudspeakers on the circuit.

POWER CONNECTOR WIRING
The MM-10ACX requires a grounded outlet. To operate
safely and effectively, it is extremely important that the entire
system be properly grounded.

CAUTION:
When creating AC power cables, it
is important to preserve AC line polarity and
connect the earth ground on both ends of the cable.
The MM-10ACX requires a grounded connection.
Always use a grounded outlet and plug. It is
extremely important that the system be properly
grounded to operate safely and properly. Do not
ground-lift the AC cable.

MM-10ACX VOLTAGE REQUIREMENTS
The MM-10ACX operates safely and continuously when the
AC voltage stays within 100–240 V AC at 50 or 60 Hz. The
subwoofer allows any combination of voltage to GND (neu-
tral-line-ground or line-line-ground).
AC voltage stays within 100–240 V AC at 50 or 60 Hz. The
subwoofer allows any combination of voltage to GND (neu-
tral-line-ground or line-line-ground).
If the voltage drops below 90 V (brownout), the MM-10ACX
uses stored power to continue operating temporarily; the
subwoofer will shut down if the voltage does not rise above
the low boundary before the stored power is used.
