WIRING FOR AC CONNECTIONS
The Acheron Designer requires a grounded outlet. To oper-
ate safely and effectively, it is extremely important that the
entire system be properly grounded.
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 Designer
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.
AC POWER DISTRIBUTION
All components in an audio system (self-powered loud-
speakers, mixing consoles, and processors) must be prop-
erly connected to an AC power distribution system to ensure
that AC line polarity is preserved, and that all grounding
points are connected to a single node or common point
using the same cable gauge as the neutral and line cables.
NOTE: Improper grounding of connections
between loudspeakers and the rest of the
audio system may produce noise or hum, or cause
serious damage to the input and output stages of the
system’s electronic components.
CAUTION: Before applying AC power to any
Meyer Sound self-powered loudspeaker, make
sure that the voltage potential difference between the
neutral and earth-ground lines is less than 5 V AC
when using single-phase AC wiring.
Figure 1 illustrates a basic three-phase AC distribution sys-
tem with the loudspeaker load distributed across the three
phases. All loudspeakers are connected to common neutral
and earth-ground lines.
