Ko70 rev. B 9 for best performance, voltage drops should not exceed 10% at 115v or 5% at 230v. The minimum electrical service amperage required by a k-array loudspeakers system is the sum of their maximum continuous rms current. We recommend allowing an additional 30% above the minimum amperage to p...
