hd HLS 20

HybridLineSource technology is a worldwide unique speaker design developed by Harmonic Design that dramatically reduces the needed truck space and improves the quality of a public address system to a new level of uniformity and complete absence of distortions. The HybridLineSource system, which is equipped with two specially developed high-performance 10″ neodymium woofers, achieves already an efficiency of 107 dB even in the low/mid range.

 

The exceedingly largedimensioned high frequency LineSource-section consists of three 1.4“ neodymium compression drivers with a special polymer diaphragm that, when coupled to a waveguide, produce a cylindrical wavefront with a vertical coverage angle of 40°. Therefore the throw of a HybridLineSource-System is comparable with a LineArray. Due to the coaxial setup the horizontal coverage pattern is free of interference in the crossover area and perfectly consistent over an angle range of 100°. Double-Hangs become redundant.

The innovative and unique case design provides for tremendous efficiency, compact dimensions and undistorted maximum sound pressure greater than 143 dB. The hd HLS20 HybridLineSource system sets new standards in all disciplines in the double 10″ class. With the use of multiple 1.4“ compression drivers the typically occurring distortion of a single driver at higher levels, is dramatically reduced another advantage is the improved headroom to cover larger distances. The special SuperVentedDesign allows for standalone applications without additional subwoofer systems a dynamic and broadband playback up to 70 Hz in full-range mode.

The mechanical design allows applications on a tripod or flown vertical arrays of up to five elements. The angle between the individual loudspeakers can be precisely adjusted from 0° to 18° in 6° increments via the integrated FastRig rigging.

Operation takes place exclusively via Harmonic Design system amplifiers and guarantees outstanding performance and compatibility even under adverse conditions as well as highest efficiency in terms of power consumption, pack size and output. Up to two speakers can be operated per channel through the Harmonic Design system amplifiers. An optional passive phase-optimized crossover allows quick and easy operation on just one amplifier channel. The 2-way BI-AMP mode provides unique neutrality and uncompromising high-end sound and is recommended for all maximum-level requirements.

The hd HLS20-RF3 is a flying frame and tripod adapter at the same time, which can be used to carry a loudspeaker on a speaker stand with precisely adjustable inclination in 1° increments from 0° – 15° as well as for flying a vertical array of up to five speakers. This gives best flexibility for daily changing applications while reducing the accessories effort.

The TourSys systems are available as perfectly tuned all-round full sound systems consisting of top speakers, subwoofers and system amplifiers. Several TourSys systems can be extended to a large system to realize sound reinforcement with up to 15,000 listeners.
