CHAPTER 2: POWER REQUIREMENTS
The Acheron Designer 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 Designer.
AC CONNECTORS
The Acheron Designer user panel includes 3-pole, Power-
Con AC connectors.
AC Input Connector (Blue)
The blue AC Input connector supplies power to the
Acheron Designer loudspeaker. The connector is rated at
20 amps and uses a PowerCon3 AC mains locking connec-
tor that prevents accidental disconnections. A 10-foot AC
power cable, rated at 15 amps, is included with each
Acheron Designer. If you replace the included AC power
cable, make sure to use a cable with the appropriate power
plug (on the other end) for the region in which you will oper-
ate the unit.
The AC Input connector also supplies power to any addi-
tional loudspeakers connected to the Acheron Designer’s
gray Loop Output connector. Each Acheron Designer loud-
speaker requires approximately 3.24 A rms maximum at
115 V AC and 1.74 A rms maximum at 230 V AC for proper
operation.
CAUTION: When using the included AC power
cable, do not loop more than three additional
Acheron Designers from the AC Loop Output con-
nector at 115 V (four total for the circuit), and not
more than seven at 230 V (eight total for the circuit).
AC Loop Output Connector (Gray)
The gray AC Loop Output connector allows multiple
Acheron Designers to be looped and powered from a single
power source. Connect the AC Loop Output of the first
Acheron Designer to the AC Input of the second unit, and so
forth. The AC Loop Output uses a PowerCon3 AC mains lock-
ing connector that prevents accidental disconnections.
The maximum number of loudspeakers that can be looped
from the Loop Output connector is determined by the volt-
age 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 Acheron Designer.
NOTE: The Acheron Designer current draw is
dynamic and fluctuates as operating levels
change. The numbers in Table 1 assume that operat-
ing levels are normal and not such that the loud-
speakers are constantly limiting.
Each Acheron Designer ships with one AC looping connec-
tor for making AC looping cables. Assembled AC looping
cables are available from Meyer Sound.
CAUTION: Do not exceed the current capabil-
ity of the 20-amp Input connector for the
Acheron Designer. When looping loudspeakers, con-
sider the total current draw for all loudspeakers on
the circuit, including the first loudspeaker.
