    KR400S 6. SAFETY WARNING • It is important that loudspeaker systems are used in a safe manner. • Professional loudspeakers are capable of producing extremely high sound levels and should be used with care. Hearing loss is cumulative and can result from levels above 90dB if people are exposed for an extended period.

  • Page 13: Amplifier

    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.

  • Page 14: Rear Panel

    For best performance, the AC Cable voltage drop should not exceed 10% at 115V and 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 prevent peak voltage drops at the service entry.

  • Page 15: Power Connector Wiring

    KR400S 8.5 POWER CONNECTOR WIRING The KL21ma’s amplifiers receive DC power from the 3-pin blue PowerCon connector on their back panel. The white PowerCon connector is a parallel OUTPUT for supplying power to other devices (max 5A @110V supported). When AC power is applied to the speaker, the auto-range power supply automatically selects the correct operating voltage.

  • Page 16: Amplification And Protection Circuitry

    KR400S 8.7 AMPLIFICATION AND PROTECTION CIRCUITRY The KL21ma is powered by a 2-channel high power digital amplifier feeding the connected KR400 modules with a power output of 1800W in each channel. All the specific functions for the KL21ma, such as crossovers, frequency, phase response, and driver protection are determined by a DSP processor installed inside the amplifier.
