CHAPTER 2: POWER REQUIREMENTS
The Acheron loudspeaker combines advanced loudspeaker
technology with equally advanced power capabilities.
Understanding power distribution, voltage and current
requirements, and electrical safety guidelines is critical to
the safe operation of the Acheron.
AC CONNECTOR
The Acheron AC connector supplies AC power to the unit
and is located on its rear user panel. The Acheron can be
equipped with one of the following AC connectors:
■ IEC 309 male inlet connector.
■ NEMA L6-20 (twistlock) male inlet
The Acheron requires a grounded outlet. To operate safely
and effectively, it is extremely important that the entire sys-
tem be properly grounded.
If you replace the included AC power cable, make sure to
use a cable that is wired correctly and equipped with the
with the appropriate power plug (on the other end) for the
area in which you will operate the unit.
AC Power Cable with Edison Adapter
The Acheron can be powered from a standard three-prong
Edison outlet with an L6-20 to Edison adapter (available for
purchase from Meyer Sound; PN 27.033.024.03).
AC Connector Wiring
When wiring international or special-purpose AC power
cables and connectors, use the following wiring scheme:
■ Connect the blue wire to the black terminal, or the termi-
nal marked with an N.
■ Connect the brown wire to the red terminal, or the termi-
nal marked with an L.
■ Connect the yellow and green wire to the green (or green
and yellow) terminal, or the terminal marked with an E.
CAUTION: When creating AC power cables
and distribution systems, it is important to pre-
serve AC line polarity and connect the earth ground
on both ends of the cable. The Acheron 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.
