DCC Series Digitally Controlled Column Loudspeakers Make UK Debut at PLASA
The new Renkus-Heinz DCC Series Digitally Controlled Column loudspeakers will make their UK début on the Beyerdynamic UK stand at PLASA 2005.
The DCC Series uses advanced technology to provide intelligible speech and musical sound in highly reverberant environments. Their slender “thin stick” vertical profile mounts flat to the wall, blending easily with both classical and contemporary architecture. The integrated system inside provides a powerful new solution for consultants, contractors and architects who need precisely controlled acoustic energy for intelligible, musical sound in houses of worship, transportation terminals and similar venues.
Systems are available in 8, 16, 24 and 32 channel sizes to suit different needs. All are constructed from the basic DCC8 8-channel module to simplify shipping and transportation. The modules are easily joined together in the field to form the DCC16, DCC24 and DCC32. Advanced DSP software and true digital amplification enables the designer or operator to define the shape and aiming of the vertical beam without moving the DCC columns from their installed position.
The 16-channel DCC16 measures just 6 x 6 x 74.5 inches (152 x 152 x 1892 mm). It delivers constant SPL over large distances (300 ft / 92 meters plus). Coverage is both controllable and consistent. This is due to meticulous acoustical engineering and the use of purpose-designed co-axial transducers. Windows-based Renkus-Heinz LobeWare software displays the pattern and aiming angle selected in the vertical plane. Beams can be symmetrical, asymmetrical or dual and can be custom shaped to fit specific applications. Horizontal dispersion is fixed at a nominal 150° between -6dB points. Additional DCC8 modules can easily be added to the basic DCC16 system to extend DCC Series’ vertical pattern control to even lower frequencies.
Each DCC Series driver is driven by an individually processed signal, delivered by an 8-channel processor/amplifier module specially developed for this purpose by D2 Audio. The D2 Audio design not only performs the complex digital signal processing required for controlled coverage, but it also converts a standard PCM (Pulse Code Modulation) input to eight PWM (Pulse Width Modulation) signals that drive the amplifiers. This eliminates the need to convert PCM to analog and analog to PWM, which would be required with ordinary Class D amplifiers. For seamless integration of the DCC8 into a complete digital solution, CobraNet connectivity can be specified as an option.
“We’re pleased that we’ve been able to develop a new loudspeaker design that can deliver the benefits of adaptable coverage through precisely controlled interference,” says Renkus-Heinz Vice President Ralph Heinz. “The integration of software with intelligent acoustical design and next-generation electronics that transmit the proper signals to each driver entirely in the digital domain results in a new level of accuracy and precision.
