"Große Halle" with modern sound reinforcement system
The Great Hall in the sports forum Berlin offers space for about 1700 spectators and is used today mainly for training and competition of the 2nd Bundesliga team of the volleyball club Olympia Berlin. Other outstanding events take place in the sports judo, archery, badminton and gymnastics in the Great Hall. Thus, the hall was the venue for the junior team cup in gymnastics, the European Cadet Cup U17 and the U21 in judo.
From the existing and future requirements, the operators decided for a high-performance sound system from K.M.E. A homogeneous sound distribution with absolute speech intelligibility in the stands and the playing field was the proviso. These could be achieved by a combination of Pano Line Arrays, flown Pano Subwoofers and Fisco installation loudspeakers. For the stands four line arrays with 4x Pano QL 906 and 2x Pano QL 1215 as downfill as well as two subwoofer hangs with 3x Pano QLB 118X each are used. The central positioning allows for perfect sound reinforcement with a maximum amount of direct sound. For the sides hybrid loudspeakers QF 5045 V2 from the Pano series are used. Four Fisco IPS 10 cover the field.
The entire set-up is powered by digital power amplifiers DA 230 and DA 428. Two Dante cards installed in the DA 428 take over the signal routing to the sound system. The network-capable digital power amplifiers can be remotely controlled and thus integrate seamlessly into the building technology.
This project was implemented in cooperation with B.I.N.S.S. Media Technology GmbH.

Line Source Element QL 906 90° x 6°
The 2-way line source unit QL 906 is equipped with two 1“ drivers coupled to a waveformer and two 8“ neodymium speakers combined with outstanding AQF acoustic filters. This filters, compounds of reticulated aminoplastic foams, dampen standing waves inside the speaker system and cancel parasetical side-lobars within the working direction, creating a wide while smooth horizontal dispersion and a perfect vertical scalability.
Line Source Element QL 1215 120° x 15° (Downfill)
The 2-way line source unit QL 1215 is equipped with two 1“ drivers coupled to a waveformer and two 8“ neodymium speakers combined with outstanding AQF acoustic filters. This filters, compounds of reticulated aminoplastic foams, dampen standing waves inside the speaker system and cancel parasetical side-lobars within the working direction, creating a wide while smooth horizontal dispersion and a perfect vertical scalability.
High Power Subwoofer QLB 118 X Flying Version
The direct-radiating high-performance subwoofer is equipped with a new developed 18” subwoofer with tetra coil & dual voice coil. The tunnel design of the bass reflex casing has been optimized to minimize air flow noise. These innovations distinctly increase the sound and reproduction quality. Hence the QLB 118 X sound tight and feature a proper impulse response without loosing the deep bass reproduction of a 18“ subwoofer. It is recommended as a universal subwoofer for creating powerful bass arrays in combination with the line array and hybrid elements of the PANO series. Its mechanical construction provides the KME typical stability. Functional details set new standards – perfectly placed handles, stacking elements and the QLB 118X with the integrated Quick Release Hardware system which enables flying and groundstacking in combination with the PANO line array elements.
Hybrid Source Element QF 5045 V2
The single hybrid array element QF 5045 V2 (newly developed high frequency unit) with a dispersion of 50° horizontal and 45° vertical is an absolute novelty in the combination of line source and point source technologies. The QF 5045 V2 contains a high frequency unit with 4 x 1“ HF drivers which are coherently working on a waveguide guaranteeing a precise dispersion and seamless transition of the high frequencies between the array elements. The mid range system is a direct radiating 12“ neodymium speaker. In this system the requirements for compact dimensions, high SPL and defined dispersion of a line array are combined in a symbiosis. The tonal tuning enables the operation of the 2-way system as full-range system or as mid/high system within a powerful PA combination. The QF 5045 V2 is optimized for clustering of maximum three units both in groundstacking and flying mode. Furthermore, thanks to the integrated flange, the operation on a high stand is possible.
