Being part of KELONIK GROUP, KCS division has a wide professional expertise in cinema sound systems, backed by fifteen years of experience and a large customer base worldwide. We are globally represented by our international KCS Distributor Network in the five continents.

Through continuous research and new product development for years, KCS has fulfilled customer demands in terms of optimised features, high performances, variety of models for any market needs, and efficient service.

With the advent of the new 3D digital projection formats, audio systems in movie theatres need to evolve so that the audience can be immersed in the sound field and enjoy a true 3D sound experience.

KCS is highly implicated in the development of such sound systems aimed for Dolby Atmos, Auro 11.1 or similar.


Three- way screen channel cinema sound system for medium capacity theaters.

K.C.S. S-7600 and S-7601 three-way speaker systems are designed for the screen channel in medium size auditoria. Their 47 cm depth makes them especially suitable where there is a space limitation behind the projection screen. S-7600 (passive) system has a passive crossover with cut frequency at 380 Hz between the low and mid ranges and 1.8 kHz between the mid and high ranges. S-7601-P (biamplified) system has a passive crossover with cut frequency at 1.8 kHz between the mid and high ranges. Between mid and low frequencies, this system is designed to operate with an external active crossover with cut frequency at 380 Hz.

The high dynamics demanded to screen channel speaker systems by current digital soundtracks requires the use of three-way systems in order to ensure high S.P.L. levels in the auditorium while keeping distortion at inaudible levels. Each of the three ways in S-7600 and S-7601 speaker systems is controlled by transducers which are specifically designed to operate in the required frequency range and ensure a precise and distortion-free reproduction. These speaker systems feature a bass cabinet with direct radiation technology, fitted with two 15” Ø speakers. Voice spectrum in this three-way design is reproduced by one 6.5” cone speaker and one 90º x 40º constant dispersion horn, improving intelligibility of dialogues as compared to conventional two-way speaker systems. Its high-frequency section consists of a
compression driver with titanium membrane and a constant directivity horn..
