Beamforming Technology in “Mother Church” of Korea

The Saemoonan Presbyterian Church was founded in Korea in 1887 and is the first organized church. Since the beginning of their mission, 21 district churches have been established in Seoul and the Gyeonggi region. In this way, they have provided spiritual and social lifelines to the Protestant churches in Korea. For this reason, it is known as the “mother church” of Korea.

With the gigantic new construction project of the sixth church building new challenges were sought and an architectural masterpiece realized: 19 floors, 68m building height, 80m church tower and a capacity of 2,200 persons in the Great Chapel. The entire sound system was installed almost invisibly in the walls behind acoustic fleece. (more…)

hd HLS20-TourSys1 Test Report in Tools4Music

In issue 01/2019, the specialist magazine tools4music is testing the hd HLS20P-TourSys1 in a live test in three completely different events: Open-Air, town hall and Rock-Band. Due to the high speech intelligibility and range of the compact hd HLS20 top all disciplines are mastered with flying colors and the system can convince even in difficult rooms. The author concludes with the words:

The hd HLS20 TourSys1 system convinces all along the line. Sound quality, throw range, low-end and sound pressure – all this offers the test system at a high, probably even the highest level. Especially the speech intelligibility in acoustically difficult rooms and the range of the compact top part impressed me compared to conventional array solutions. The PA sounds mighty, but is compact in comparison to the output. A combination that is popular with ambitious touring bands and rental companies

Harmonic Design – new in the sales department of Laauser & Vohl GmbH

+++ Press release Stuttgart, 13.12.2018 +++
The older ones among us will know the brand from the 1990s, as it was already then for innovation and quality standards in professional speaker systems. A few years ago, Harmonic Design was taken over by a young team from the Swabian town of Steinheim an der Murr and developed into a technologically leading manufacturer within a very short time. At the beginning of the year 2019, Laauser & Vohl GmbH from Stuttgart will take over Germany’s distribution of Harmonic Design products. Harmonic Design is characterized by proprietary state-of-the-art technology in electronics and DSP, state-of-the-art loudspeaker design and manufacture, and exclusively in Germany. Outstanding here are in particular the two product lines HLS (HybridLineSource) high-performance loudspeakers and the DSP-controlled LineArray beamforming loudspeakers of the hd ML- and PL-Series. The performance characteristics of these systems go far beyond the previously available products of similar design. (more…)

EDM-Clubinstallation in Vietnam

The Peerage Bar is a newly opened premium club in the heart of Hai Phong, the booming metropolis of northern Vietnam. In line with the state-of-the-art lighting design with lasers, LED-Sceens and countless moving lights, an extremely powerful Harmonic Design loudspeaker system has been installed.

A total of 8x hd HLS24 in BI-AMP operation provide a disco feeling of the extra class. The high-frequency section integrated in the revolutionary HybridLineSource loudspeaker, each consisting of 4x 1.4″ drivers, enables the lowest possible distortion with extremely high listening volumes. As a result, hearing does not tire as quickly as is the case with conventional Club PA systems. The horny and powerful low center section of the hd HLS24 allows a fast and dry kick bass reproduction of EDM music styles in fullrange mode – without additional kick bass way. (more…)
