CHAPTER 1: POWER REQUIREMENTS

The M2D and M2D-Sub loudspeakers represent advanced
technology with equally advanced power capabilities.
Understanding power distribution, voltage and current
requirements, as well as electrical safety issues, is critical
to their safe operation and deployment.

AC POWER

The M2D and M2D-Sub loudspeakers use a PowerCon
���
3-pole AC mains system with locking connectors to
�
����
prevent accidental disconnection or a multipin VEAM™
male power connector (Figures 1.1, 1.2 and 1.3).

CAUTION:
correct power plug for the AC power in the
area in which you use your loudspeaker.
When AC power is applied to the M2D or M2D-Sub
loudspeaker, the Intelligent AC power supply automatically
selects the correct operating voltage, allowing the
loudspeakers to be used internationally without manually
®
setting voltage switches. The Intelligent AC supply
performs the following protective functions to compensate
for hostile conditions on the AC mains:
 Suppresses high-voltage transients up to several
kilovolts
 Filters common mode and difference mode radio
frequencies (EMI)
 Sustains operation temporarily during low-voltage
periods
 Provides soft-start power-up, which eliminates high
inrush current

AC Power Distribution

All amplifier modules and directly associated audio
equipment (mixing consoles, processors, etc.) must
be connected to the AC power distribution in a proper
manner, preserving AC line polarity and connecting earth
ground such that all grounding points are connected to a
single node or common point using the same cable gauge
as the neutral and line(s) cable(s).
Improper grounding connections between loudspeakers
and the rest of the audio system may produce noise, hum
and/or serious damage to the input/output stages in the
system's electronic equipment.
CAUTION:
Meyer Sound self-powered loudspeaker, be
sure that the voltage potential difference between
neutral and earth ground is less than 5 volts AC.
Ensure that you select the
