KHARKIV Kharkiv sits in the east of Ukraine, close to the border with Russia. The second largest city in the country is home to the Metalist Stadium, which has been nicknamed ‘spider’ because of the 24 roof supports that arch like spider’s legs from the bowl to the ground outside. The new architectural appearance is the result of an upgrade to the Kharkiv Arena, which was designed to not only make the venue viable for Euro 2012, but to create a modern, multi-functional sports complex and entertainment facility. The modernisation has touched all parts of the complex: the south grandstand was added, the eastern one was rebuilt, and the northern and western - were reconstructed. In turn, the employees saved the facility’s objects that are monuments of architecture. The arena itself can hold 38,633 seated spectators. Kompeks-V, which represents Bose in the Ukraine, took charge of the audio infrastructure at the stadium. Using Bose’s Modeler software, the company created a 3D model of the sports venue. That model was then used to pinpoint optimal speaker points. Using a computer-based 3D model of the acoustic space and advanced acoustic ray tracing algorithms, Modeler can be used to predict a sound system’s performance. It uses full STI prediction - a measure of speech transmission quality. The software takes into account the acoustic characteristics of building materials that were used during construction, and automatically takes into account the sound absorption coefficient. Other parameters, such as background noise are also fed into the model. One of the key factors that needed to be considered was the distance from speaker to seat, which was calculated at a maximum of 20 metres. It was formulated that over that distance, a 26dB drop off would be incurred, thus to achieve the nominal level of sound, a system that produced 138dB at one metre would be required. Kompek-V’s line of enquiry arrived at Bose Panaray LT speakers, which are recognised for their strengths in open outdoor areas and large, echoing rooms. Based on the calculations, a system of distributed clusters was decided on. These clusters come in five different formations and are used in differing volumes. The first cluster, which consists of three

Bose LT MB24 subwoofers, has been used 22 times around the stadium, evenly spaced under the roof. The second comprises a Bose LT 9402 speaker aimed at the upper part of the stadium and a Bose LT 4402 speaker aimed at the lower. A total of 16 of this second cluster type are located under the roof of the east and west zones. Two different speakers have also been used for the third cluster, which are found in the north and south zones - 22 in all. This time a Bose LT 9702 speaker is aimed at the middle section of the seating and a Bose LT 4402 is again pointed at the lower part of the stadium. The upper parts of these zones are serviced by 16 of the fourth cluster, which is a single Bose LT 9400. And the very top zone of the north and south sections are taken care of by the fifth cluster, which is made up a of Bose LT 6400. Again, 16 were needed across the two zones. Amplification for the system comes from a combination of Bittner and MC² units. The subwoofers are powered by 35 MC² Ti-3500 amplifiers and the other speakers by 30 Bittner XR2500 amplifiers. All of the amps and audio processing is taken care of by Bose Control Space ESP-88 processors that are situated in rooms located on the north, south, east and west stands. All of the audio signals are passed through a fibre optic CobraNet network. The visual aspect of the stadium, including two large entertainment screens and the digital advertising boards that boarder the field of play, are manufactured by Barco.
