CAUTION:
For 230 V AC, 3-phase Wye sys-
tems, never connect two lines to the AC input
of LEOPARD, as the resulting voltage would exceed
the upper voltage limit (275 V AC) and will damage
the loudspeaker.
AC CONNECTORS
The LEOPARD user panel includes two powerCON 20
connectors (Figure 10), one for AC Input (blue) and one for
AC Loop Output (gray).
Figure 10: AC Input (Left) and AC Loop Output (Right) Connectors
AC Input (Blue)
The blue AC Input connector supplies power to LEOPARD.
The 3-conductor powerCON 20 is rated at 20 A and uses a
locking connector that prevents accidental disconnections.
A 10-foot AC power cable, rated at 15 A, is included with
each loudspeaker. 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 area in which you will operate
the loudspeaker. LEOPARD requires a grounded outlet. To
operate safely and effectively, it is extremely important that
the entire system be properly grounded.
The AC Input connector also supplies power to any
additional loudspeakers connected to the loudspeaker's
gray Loop Output connector.
CAUTION:
When looping AC power for loud-
speakers, do not exceed the current capability
of the AC Input connector (20 A) or the included AC
power cable (15 A). Consider the total current draw for

all loudspeakers on the circuit, including the first loud-
speaker (Table 1).
AC Loop Output (Gray)
The gray AC Loop Output connector allows multiple
LEOPARDs to be looped and powered from a single power
source. The 3-conductor powerCON 20 is rated at 20 A and
uses a locking connector that prevents accidental
disconnections. For applications that require multiple
LEOPARDs, connect the AC Loop Output of the first
loudspeaker to the AC Input of the second loudspeaker, and
so forth.
The maximum number of loudspeakers 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
loudspeakers, the circuit breaker rating, and the rating of the
AC power cable connected to the first LEOPARD
loudspeaker (Table 1).

NOTE:
Current draw for LEOPARD is dynamic
and fluctuates as operating levels change. The
indicated number of loudspeakers that can be looped
assumes that operating levels are normal and not
such that loudspeakers are constantly limiting.
LEOPARD ships with a gray powerCON 20 cable mount
connector, rated at 20 A, for assembling AC looping cables.
Assembled AC looping cables are also available from Meyer
Sound.
CAUTION:
When looping AC power for loud-
speakers, do not exceed the current capability
of the AC Input connector (20 A) or the included AC
power cable (15 A). Consider the total current draw for
all loudspeakers on the circuit, including the first loud-
speaker (Table 1).
