AMIE-SUB OPERATING INSTRUCTIONS

230 V AC, 3-Phase Wye System (Single Line)
Line-Neutral-Earth/Ground
Figure 6 illustrates a basic 230 V AC, 3-phase Wye
distribution system with the loudspeaker load distributed
across all three phases, with each loudspeaker connected
to a single line and common neutral and earth/ground lines.
This system delivers 230 V AC to each loudspeaker.
CAUTION: For 230 V AC, 3-phase Wye sys -
tems, never connect two lines to the AC input
of Amie-Sub, as the resulting voltage would exceed
the upper voltage limit (275 V AC) and will damage
the loudspeaker.
AC CONNECTORS
The Amie-Sub user panel includes two powerCON 20
connectors (Figure 7), one for AC Input (blue) and one for AC
Loop Output (gray).
AC Input (Blue)
The blue AC Input connector supplies power to
Amie-Sub. 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 the included AC power
cable is replaced, make sure to use a cable with the
appropriate power plug (on the other end) for the region
where the unit will be operated. Amie-Sub 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
Amie
- Subs 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
Amie
- Subs, connect the AC Loop Output of the first
loudspeaker to the AC Input of the second loudspeaker and
so forth.
The maximum number of Amie - Subs 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 Amie-Sub
loudspeaker (Table 1).
NOTE: Current draw for Amie-Sub 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.
Amie-Sub ships with a gray powerCON 20 cable mount
connector, rated at 20 A, for assembling AC looping cables.
Assembled 1-meter AC looping cables (PN 28.115.032.03)
are also available from Meyer Sound.
