7.2 VOLTAGE REQUIREMENT
7.3 CURRENT REQUIREMENT
The amplifier module and any audio equipment connected to it (mixing consoles, processors, etc.) must be
properly connected to the AC power distribution, preserving AC line polarity. All grounding points should be
connected to a single node or common point, using the same cable gauge as the neutral and line cables. Bad
grounding connections within an audio system can produce noise, hum and/or serious damage to the input/
output stages in the system’s electronic equipment.
Before applying AC to any K-array self-powered speaker, be sure that the voltage
potential difference between neutral and earth ground is less than 5 VAC.
the Ko70’s switching power supply accommodates AC mains operating at either 115V or 230V.
The amplifier will continue to operate safely, without interruption, provided the AC voltage remains
within 85 - 270V, at 50 or 60 Hz. Please verify that your AC mains connection is capable of satisfy-
ing the power ratings for the device.
CAUTION
Do not connect the system to AC power mains exceeding 270V. Doing so will
cause significant damage to the device and create serious risk for users!
the Ko70 present a dynamic load to the AC mains, drawing additional current as operating levels increase.
Different cables and circuit breakers heat up at varying rates, so it is essential to understand current ratings
and how they correspond to circuit breaker and cable specifications. Maximum continuous RMS current -
measured over a period of at least ten seconds - is used to calculate the temperature increase in cables,
which drives the proper size and gauge cable and rating for slow-reacting thermal breakers. Maximum burst
RMS current - measured over a period of approximately one second - is used to select the rating for fast
reacting magnetic breakers.
