I Can Hear Clearly Now QFlex Has Come

The town hall of Mid-Berlin has installed a Tannoy QFlex system. The main hall where meetings are held previously suffered from high reverberation times, with large windows and solid surfaces leading to poor intelligibility. Consultants Krämer and Stegmaier decided to use digital beam-steering to solve the problem, and used available data to simulate different approaches with CATT-Acoustic. Based on the results the decision was made to use the QFlex24. The QFlex are used in an arrangement with three Kling und Freitag CA 106 for monitoring.
