The Danish Broadcasting Corporation's prestigious new venue was designed by French top architect Jean Nouvel, winner of the Pritzker Prize ("the Nobel Prize of architecture"). It contains four concert halls offering state-of-the-art acoustics to supreme world-class standards. The acoustics were designed by none other than Japanese acoustics specialists Nagata Acoustics, Inc.. KLOTZ a.i.s.' Danish partner, systems integrator AVIT Systems A/S, planned and installed the entire audio-visual infrastructure of the DR Byen complex, using KLOTZ cables exclusively throughout.

KLOTZ a.i.s. is proud to have worked with its Danish partner AVIT Systems on completing such a magnificent and prestigious project. Peter Klotz, member of the board, comments, "We have already successfully executed an array of international projects with our partner companies. Each project delivers a new challenge which we solve as a team with a high level of professionalism and even higher product quality. We are only truly satisfied when the results are convincing – and this was the case in Copenhagen.“

DR Byen Koncerthuset comprises a total of four concert halls, the main hall of which seats 1,800. The main hall is designed in tiers, with 15 balconies surrounding a central stage to ensure the audience is close to "where the action is". Together with the sophisticated architecture of the hall, this proximity to the artists on stage guarantees optimum acoustic conditions.

Studio 2, a smaller concert hall seating approximately 500, is decorated in dark colours with beechwood panels depicting Danish composers and conductors. Studio 3, the smallest auditorium, offers seating for up to 200 persons and features an interior in black and white like the keys of a piano. The proximity of audience and artists in Studio 3  creates an atmosphere of extreme intimacy. Studio 4 also seats an audience of 200. The hall has an all-red decor and a special acoustic design aimed at creating a unique atmosphere for chamber music, choral concerts and similar events.
