Congress Centrum Suhl has installed an Amadeus Active Acoustics System into its 2,350-seat Great Hall, and Renkus-Heinz loudspeakers were selected for the installation.
Congress Centrum Suhl, Germany, is a museum and art gallery in a lakeside complex.
The Amadeus System employs far more loudspeakers than microphones. CCS, built in the 1970s and remodelled in the 1990s after Germany’s reunification, had 74 wide-dispersion, ceiling-mounted loudspeakers already installed, but the Amadeus system called for additional speakers on the walls. MediasPro Medientechnik GmbH supplied 35 Renkus-Heinz CX61 compact two-way Complex Conic loudspeakers to complete the installation.
Complex Conic horns work with the spherical expansion of the acoustic pressure wave, instead of trying to force audio through a rectangular funnel, as with conventional designs. Complex Conic horns provide constant beamwidth, and as pattern control devices, they perform better over a wider frequency band than ordinary horns. The CX61’s wide 150-degree by 60-degree coverage provides proper dispersion of the reverberation signals.
CCS also installed a Dante network to carry all of the signals to and from the Amadeus Core processor at the heart of the system. Signals from the 14 Audio-Technica microphones run to an Attero Tech Synapse D16Mio Dante-networked audio interface, which puts the signals through 14 of its 16 mic preamplifiers before placing them on the network. Signal outputs from the Amadeus Core flow to the loudspeaker array across the network. The signals are converted to analogue by three Attero Tech unD32 Dante-networked interfaces, each of which features 32 analogue outputs. The unD32 outputs feed 10 Bittner 8X100 power amplifiers, each of which offers eight channels of amplification.
“The Congress Centrum is quite pleased with the performance of our new reverberation enhancement system,” stated CCS managing director Diana Schneider. “We have had many visitors tell us they had a special sound experience in the hall and thoroughly enjoyed hearing music there. I am grateful to everybody involved with the project for their very competent project design and implementation.”
