k-array KH4 音乐会音箱 有源扩声音箱
KH4是有源2分频线阵列音箱单元，外观设计非常现代优雅。KH4具有非常充足的功率储备，能够在120度的宽阔水平面上实现高声压级输出，并且保持音质优美。KH4具有坚固的铝质箱体，厚度为6″（16cm），重量也只有47kg（100lbs）。垂直覆盖角度可调，调节范围从7°到37°。这样在多用途的应用时就增加了灵活性。
KH4适合在大中型场馆做长距离扩声使用，比如在剧院、音乐厅或者教堂。KH4在设计阶段就考虑了和K-array其它产品的配合问题，比如与KS4低音线阵列音箱的配合，与KO70或KO40配合可以有效地延展系统的低频特性。
KH4采用六路功放通道驱动12只2.5″音圈的8″锥盆单元重放中低频信号，中高频信号的重播则使用5只1.75″音圈的压缩驱动单元，前端加载1″*4″的恒指向波导。高频驱动单元在箱体中间形成阵列。利用吊挂系统可调节垂直覆盖角度，调节范围从7°-37°。

The K-array KH4 is a high performance self-powered, 2-way line array speaker system. At just over 51 Kg (113.32 lb) and 16 cm deep (6 inches), its ultra-compact aluminum enclosure contains an incredible reserve of power.that ensures very high sound pressure, with wide consistent (120°) horizontal coverage. It has the unique capability for varying the vertical coverage from 7° (line array applications) to 37° (stand alone). The KH4 is suited for medium to long throw applications in theaters, stadiums, houses of worship and concert halls. The KH4 integrated with the KS4 self-powered dipole subwoofer, creates a high performance large scale solution. The KH4 can also companion with the KH15 satellite, and KO70 , KO40 self powered sub bass elements. The KH4 uses twelve 8-inch cone drivers with 2.5” voice coils for low-mid frequencies, powered by six power amplifier channels. The mid-high frequency section uses five 1.75” voice coil compression drivers mounted on 1”x 4” constant directivity waveguides. The drivers form an array exactly in the centre of the speaker. A mechanical system can provide different vertical coverage from 7° to 37° on each KH4. An internal DSP module provides configuration presets. Dedicated remote control software allows for control of the speaker from a computer. All KH4 components are designed by the K-array R&D department and custom made under the K-array quality control system in Italy.
