FEATURES AND APPLICATION
| Self-powered Integrated DSP and remote control Onboard touch screen with matrix control RS485 and USB connectivity for remote control Digital acoustic steering |
Medium scale events |
DESCRIPTION
– Research conducted over 10 years which was used to develop the next generation of touring systems, the Firenze Series, has also been applied to the new line of K-array speakers, the Concert Series.
– This groundwork led to significant advancements including the ability to digitally steer the sound, the use of an onboard touch screen and an intelligent integration of capabilities such as various stacking and hanging positions, weather resistance and integrated DSP multiple analog and digital inputs. And with the K-dante accessory, the system can be used in Dante network. The company’s signature compact design, Slim Array technology, is also implemented.
– The KH3 in the K-array Concert Series was designed with larger scale events in stadiums, arenas, concert halls and theatres in mind. The unique performance-to-size ratio measures up two large 12” neodymium magnet woofers with a 2.5” voice coil each and two 1.4” compression drivers with a 2.5” voice coil each. The medium to large format speaker has the ability to drive sound farther.
All KH3 components are designed by K-array and custom-made under K-array’s quality control system.
