Convention Paper
2-Bus Conference System for the European Central Bank (ECB), Frankfurt
AES Convention 112 · Paper 5601 · April 2002
Abstract
In the European Central Bank (ECB) in Frankfurt, new conference and press conference rooms with audio and media-technical equipment will be outlined and described. Conference systems, with more than 150 delegate stations, spread over 3 rooms and including two separate audio buses can be used for e.g. presidential or participant positions. Using separate controls at the mixing desk, various frequency responses and separate limiters, each station is capable of individual settings. The operation procedure is carried out PC-controlled through a touch screen with the possibility of storing system configurations. In each conference room compact loudspeaker boxes with good frequency response are mounted above the perforated surface of the ceiling. Before installation, tests and verifications were carried out through the program Modeler to check the acoustical transmission of ceiling material and to calculate sound fields. Media technical installations were integrated with video projection, cable and glass fiber connections to ensure a link to O.B. Vans as well as to radio/TV stations over existing broadband fiber networks. Concepts, design, measurement results and experiences will be presented.
