7.9 AMPLIFICATION AND PROTECTION CIRCUITRY

The KO40 is powered by the K-array digital power amplifier with a total power of 3000 watts.
All the specific functions for the KO40 such as crossovers, frequency, phase response, and loudspeakers
protection are determined by a DSP processor installed inside the amplifier.
All K-array speakers are shipped with the cone drivers in correct alignment. However, if a loudspeaker needs
to be replaced, make sure the replacement is reinstalled with the correct polarity. Incorrect cone driver polarity
impairs the system performance and may damage the component.
