All amplifier modules and the rest of the audio equipment connected to it (mixing consoles, processors, etc.) must be connected to

the AC power distribution in a properway, preserving AC line polarity and connecting earth ground such that all grounding points are

connected to a single node or common point using the same cable gauge as the neutral and line(s) cables. Bad grounding

connections between speakers and the rest of the audio system may produce noise, hum and/or serious damage to the input/output

stages in the system’s electronic equipment.

The KH4 or KS4 operates safely and without audio discontinuity if the AC voltage stays within either of two operating windows:
95-125 or 195-250 V, at 50 or 60 Hz.

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.

If the Display does not illuminate or the system does not respond to

audio input after ten seconds, remove AC power immediately. Verify that

the voltage is within the proper range. If the problem persists please

contact HP Sound Equipment or an authorized service center.

It is recommend that the supply be operated in the rated voltage windows, at

least a few volts away from the turn on/off points so that small AC voltage

variations do not cause the amplifier to cycle on and off.

NOTE

The main power supply slowly ramps on t he green display on the user panel lights up, and the green leds on the left side lights

up flashing, indicating that the system is enabled and ready to process audio signals
