AC Cable Color Coding
If the colours referred to in the diagram don’t
correspond to the terminals in your plug, use
the following guidelines: Connect the blue wire
to the terminal marked with a N or coloured
black. Connect the brown wire to the terminal
marked with an L or coloured red. Connect
the green and yellow wire to the terminal marked
with an E or coloured green or green and yellow.
Safety Summary
To reduce the risk of electric shock, disconnect
the loudspeaker from the AC mains before
installing audio cable. Reconnect the power
cord only after making all signal connections.
Connect the loudspeaker to a two pole,
three-wire grounding mains receptacle.
The receptacle must be connected to a
fuse or circuit breaker. Connection to any
other type of receptacle poses a shock
hazard and may violate local electrical codes.
Do not allow water or any foreign object
to get inside the loudspeaker. Do not put
objects containing liquid on or near the
unit. To reduce the risk of overheating the
loudspeaker, avoid exposing it to direct
sunlight. Do not install the unit near heat-
emitting appliances, such as a room heater
or stove. This loudspeaker contains potentially
hazardous voltages. Do not attempt to
disassemble the unit. The unit contains no user
serviceable parts, repairs should be performed
only by factory trained service personnel.

Current Requirements
Each EX6 requires approximately 2.5 Amps
max at 115V AC for proper operation.
This allows up to six EX6’s to be powered
from one 15 A breaker at 115V and up to
twelve EX6’s at 230V.
The EX6 presents a dynamic load to the
AC mains, which causes the amount of current
to fluctuate depending on quiet or loud
operating levels. Since different cables and
circuit breakers heat up at varying rates, it is
essential to understand the types of current
ratings and how they correspond to circuit
breaker and cable specifications.
The maximum long-term continuous current
is the maximum rms current during a period
of at least ten seconds. It is used to calculate
the temperature rise in cables, in order to select
a cable size and gauge that conforms to
electrical code standards. It is also used to select
the rating for slow-reacting thermal breakers.
The burst current is the maximum rms current
during a period of approximately one second,
used to select the rating of most magnetic
breakers and to calculate the peak voltage
drop in long AC cables according to the formula:
V pk (drop)= I pk x R (cable total)
The ultimate short-term peak current is used
to select the rating of fast reacting magnetic
breakers. Use the table below as a guide
when selecting cable gauge size and circuit
breaker ratings for your operating voltage.
