Allround PA-System

Revolutionary HybridLineSource technology.

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 12″ neodymium woofers, achieves an efficiency of 108 dB even in the low/mid range.

Powerful LineSource-Unit makes the Difference.

The exceedingly largedimensioned high frequency LineSource-section consists of four 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.

Efficiency new Defined.

The innovative and unique hybrid horn-loaded-, vented-, coaxial- and LineArray- enclosure design ensures seamless efficiency, most compact dimensions and undistorted high SPL larger 144 dB. The hd HLS24 HybridLineSource system sets new standards in all disciplines in the double 12″ 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 ensures a dynamic and broadband reproduction below 60 Hz without additional subwoofers in standalone full range mode.

Easily Combinable.

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.

Reliable and Audiophile.

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.

Sophisticated Accessories save Time and Money.

The hd HLS24-RF3 is a flying frame and tripod adapter at the same time, which can be used to carry a loudspeaker on a stand with precisely adjustable inclination in 1° increments from 0° – 15° as well as to fly a vertical array of up to five loudspeakers. This gives best flexibility for daily changing applications while reducing the accessories effort.

Sound with System.

The TourSys systems are available as perfectly tuned all-round sound reinforcement 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.
