KV2 Audio EX26 - Manual (Page 6)

NOTE: It is recommended that the
voltage supply be within the rated
voltage window. This ensures that
AC voltage variations from the service entry -
or peak voltage drops due to cable runs - do
not cause the amplifier to cycle on and off or
cause damage to the power supply.
NOTE: For best performance, the AC
cable voltage drop should not exceed
10 volts, or 10 percent at 115 volts
and 5 percent at 230 volts.
Make sure that even with the AC voltage drop,
the AC voltage always stays within recommended
operating ranges. The minimum electrical service
amperage required by an EX26 speaker system
is the sum of each loudspeaker’s maximum
continuous rms current. An additional 50 percent
above that amperage is recommended to prevent
peak voltage drops at the service entry.
The Power Connector
The EX26 requires a grounded outlet. It is very
important that the loudspeaker AC supply be
properly grounded in order to operate safely
and properly. Use the PowerCon AC cable-
wiring diagram overleaf to create international
or special-purpose power connectors:

Chapter 1: AC Power Requirements
The EX26 is an advanced self-powered loud-
speaker with on-board amplification and con-
trol systems. Understanding power distribu-
tion, voltage and current requirements, as well
as electrical safety issues, is critical to the safe
operation of the EX26.
AC Power
The EX26 uses a PowerCon 3-pole AC main
system with locking connectors to prevent
accidental disconnection. The main AC
connector (blue) serves as the power input.
The EX26 operates in either 115V or 230V
modes. Although pre-configured at the facto-
ry, the unit’s operating voltage mode can be
changed in the field.
Voltage Requirements
The EX26 operates safely and without audio
discontinuity if the AC voltage stays within
the operating window of 100V-130V in 115V
mode and 200V-250V when working in 230V
mode, at 50 or 60Hz.
CAUTION: If the On LED does not
illuminate or the system does not
respond to audio input, remove AC
power immediately. Verify that the voltage is
within the proper range. If the problem
persists, please contact KV2 Audio or an
authorized service center.
If the voltage drops below the low boundary
of its safe operating range, the loudspeaker
will shut down if the voltage does not rise
above the low boundary before storage circuits
are depleted. How long the loudspeaker will
continue to function during brownout depends
on the amount of voltage drop and the audio
source level during the drop. If the voltage
increases above the upper boundary of the
range, the power supply can be damaged.
