Meyer Sound 80 ユーザーズマニュアル

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.

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.

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).

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.

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.
