Renkus-Heinz delivers steerable sound to Istanbul town hall

Üsküdar's Town Hall in Istanbul has been fitted with sound systems based on Renkus-Heinz digitally steered line arrays by Eramita, the integrators that designed and installed the AV systems for the entire facility.

Üsküdar was founded in the 7th century BC and is one of Instanbul’s oldest residential areas with a high concentration of historic buildings and religious sites.

The town hall, however, is new and entirely modern serving as a multipurpose community centre, which includes two auditoriums, a multi-purpose hall, a cocktail hall, and a basketball arena.

The two pizza-slice-shaped auditoriums, dubbed Red Hall and Blue Hall, each seat 442 people, although the Blue Hall is slightly larger. Each features a 7m ceiling and a balcony without seats that wraps around the room from one side of the stage to the other. The mostly plasterboard ceiling includes four metal acoustic panels in the middle, and the walls are half wooden panels and half fabric-covered acoustic panels.

The Red and Blue Hall sound systems each use a pair of Renkus-Heinz IC Live Gen5-series IC-F-RN arrays, mounted to the outer face of the balcony, left and right of the stage. A pair of Renkus-Heinz PN61R self-powered two-way Complex Conic loudspeakers serves as front fills, and two Renkus-Heinz CF121M-2 powered two-way Complex Conic loudspeakers provide stage monitoring. Two PN212-SUB dual 12in subwoofers deliver plenty of natural sounding low end. In each auditorium, a Roland M-200i 32-channel digital console handles mixing and routing duties.

“With Renkus-Heinz’ steerable beam technology, we were able to cover the Red Hall and Blue Hall with the best sound, using the minimum number of loudspeakers,” explained Burcin Cakin of Eramita. “The beams deliver the sound to the seats and keep it off the walls and the face of the balcony. The IC Live Gen5 series is suitable for a wide variety of music and other programming, especially when paired with PN-series subwoofers, which made it the right choice for these halls.”

The Cocktail Hall, which is also pizza-slice-shaped, is replete with rich, red drapery and has a sloped ceiling that rises from 4.5 to 4.7m. Here, too, the main system features a pair of Renkus-Heinz IC-F-RN arrays, which match the wall colour between sets of drapery. Neither subwoofers nor fills are needed but the wide, low stage is served by two Renkus-Heinz CF121M-2 stage monitors. The Roland M-200i console in this space is conveniently rack-mounted.

The rectangular Multi-Purpose Hall features extensive glass façades covered with royal blue curtains. The sound system in this space again employs two Renkus-Heinz IC-F-RN arrays, two Renkus-Heinz CF121M-2 stage monitors, and a rack-mounted M-200i console. “In the Multi-Purpose Hall and the Cocktail Hall, Renkus-Heinz beam steering enables us to provide intelligible, very high quality sound for both speech and music throughout the room, without overpowering any area,” stated Cakin. “Patrons enjoy clear, accurate sound without feeling overwhelmed. Yet the system easily has all the power we need.”

The indoor basketball arena seats 800, including bleacher-type lower seating and balconies on both sides. With ceilings that vary from 12.65 to 15.95m and painted plaster walls, intelligibility and high reverberation times were major issues. For this more challenging space, the Eramita team chose a pair of Renkus-Heinz ICONYX Gen5-series IC32-RN digitally steerable arrays, each which enables up to 16 beams to be individually shaped and aimed. These main arrays are mounted to the left and right of the court, at the end of the seating areas. A pair of ICONYX IC8-RD arrays, each of which can deliver up to four steerable beams, series serves the entrance area.

Two Renkus-Heinz CF121-2 powered two-way Complex Conic loudspeakers serve as fills for the left and right balconies. The CF121-2 is similar to the CF121M-2 but the latter is primarily used for stage wedges and foldback systems, while the CF121-2 is more often employed as unobtrusive mains or as fills in a larger system, as in the Üsküdar basketball arena.
