The Thalia Theater in Hamburg has chosen an Alcons QR36 system as its main sound reinforcement system.

After many tests and measurements, Florian Scheunemann, head of sound department and Tobias Wursthorn, planning-assistant of the theatre, decided to go for QR36 pro-ribbon loudspeakers. The QR36 is a line-source column, which combines the simple handling of a point-source system with the throw and coverage of a line-array.

The idea was to install a sound system for the coverage of the complete ground floor, that would have the features of a line-array, in order to be able to guarantee a smooth, coherent SPL coverage. On top of that, the system would have to be installed in the wall, virtually invisible. In the summer of 2007, extensive evaluation took place with among others Alcons QR36 line-source column as well as LR14 ultra-compact line-array.

Florian Scheunemann comments: „Already after the first tests it became clear what a remarkable resolution a pro-ribbon system has, as well as how exact the dispersion of the QR’s really is. The refined architecture of the venue does not allow for every sound system design, as the ground floor seating needs to be covered without any interference. The QR’s seemed to be the perfect fit.”

Scheunemann continues: „Absolutely convincing, however, was the throw of the brilliant ribbon highs, that made a delay line obsolete. For a further system extension, we have also planned QR36 columns in the three balconies to obtain the same obstruction-free sound projection.”

The QR36 modular pro-ribbon line-source column consists of two 18“ pro-ribbon drivers, with all-natural cylindrical radiation, and six 6.5“ woofers. The QR system offers, through an active frontal radiation of 94%, a very precise projection control with maximum side-lobe suppression.

For the low-end extension, the system is supported by two BF362 subwoofers. This deep-tuned subwoofer system with it’s realistic pressure-sub reproduction comes into play for music and effects. All Alcons systems are powered and controlled by the ALC Amplified Loudspeaker Controllers with Speaker Drive Processing circuit.

Says Carsten Albrecht of Alcons Audio Germany: “The decision to use Alcons systems throughout the house makes the Thalia Theater, whose rich history dates back as far as 1843 the first-ever theatre in Germany to apply the Q-series line-source columns. It’s another proof of the growing popularity of Alcons pro-ribbon systems in the theatre market in general and the quickly raising interest in the Q-series in specific.“
