For best performance, voltage drops should not exceed 10% at 100V or 10% at 230V. The minimum electrical service amperage required by a K-array loudspeaker system is the sum of their Maximum Continuous RMS Current. K-array recommends allowing an additional 30% above the minimum amperage... -
Page 10: Protection Circuitry
Ver. 1.2 7.4 PRoTeCTIon CIRCUITRY Both the Power supply and the amplifier sections are equipped with several protection circuits. Power supply protections aim to isolate a faulty section in electrical power system from the rest of the device in order to prevent the propagation of the fault and limit device damages. They comprise overcurrent, overvoltage and thermal protections. -

9. ConfIGURaTIons 9.1 hoRn oRIenTaTIon KH7 features four loudspeakers, each composed of a 12” woofer coupled to an asymmetric horn which produced a different sound dispersion pattern in respect to its axes. The sound dispersion is wide along the axis labeled FLOOD and narrow along the axis labeled SPOT. -
Page 16: Single Unit Configurations
As shown in the figures below, the coverage angle of a single KH7 can be digitally adjusted along the axis of the four loudspeakers . Along this axis, KH7 behaves like a line array and can be digitally steered since each loudspeaker is controlled by a dedicated DSP channel of the amplifier (see Chapter 10). - Page 17 Ver. 1.2 A vertical KH7 with A vertical KH7 with vertically horizontally oriented horns oriented horns FLOOD SPOT Coverage 100° + Coverage 30° + digital adjustment digital adjustment SPOT FLOOD Coverage 30° Coverage 100°...

Ver. 1.2 11. ReMoTe ConTRol - aRMonIa All DSP functions, including system EQ, delay and the loading of FIR filters calculated with EASE Focus, can be controlled with Armonia software. Please refer to Armonia User Guide downloadable from the Powersoft website for detailed instructions. -
Page 22: Rigging
Ensure that the rubber feet are resting on the floor. To place a single unit in vertical position or to ground stack a KH7 cluster, use the accessory shown in the picture below. Up to 3 units can be stacked in horizontal position and up to two units can be stacked in vertical position. -
Page 23: Hanging Points
Ver. 1.2 12.2 hanGInG PoInTs Fasten at least four standard M8 eyebolts to hang a KH7 unit from the dedicated threaded points on the chassis (see the picture). Then use appropriate steel cables sturdy enough to hold KH7’s weight. K-array is not responsible for any rigging equipment and accessories that are not manufactured by K-array. -
