Powersoft drives high-profile Rome exhibition
- Details
Once the planning was complete, the exhibition’s creator and producer, Palzom Films, contacted Italian audio specialist, AudioFactory, to assist integrator AMP di Fabrizio Dovidio with the installation of a sound system that could live up to the expectations of such an important exhibition.
“The head of audio of Palzom Films, Alessandro Di Maio asked us an audio sound system with three main characteristics,” explained Oreste Parmentola, AudioFactory’s CEO. “It needed to be visually discreet, have high sound quality, and have the capability to be remote controlled. We were encouraged to design a state-of-the-art system using our own products. To do this, we chose to use our DESIGN product line, which has been conceived with this kind of venue and audio requirement in mind.”
As well as the quality of AudioFactory’s own speakers, Parmentola cited power amplifiers with built-in DSP as being key to answering the Vittoriano’s brief.
“Furthermore, using Dante audio streaming flux through the network was a substantial improvement in terms of reduce complexity of wiring and increase audio quality and reliability,” he said.
The system comprised of a number of AudioFactory’s DESIGN loudspeakers, including the D04 full-range 4-inch loudspeaker; the D06 full-range 6-inch loudspeaker with driver and differential horn; the D06 full-range 6-inch loudspeaker with driver and high directivity horn; and the DS10 10-inch subwoofer. This was driven by 2 Powersoft Ottocanali DSP + Dante, 5 Quattrocanali DSP + Dante, and 2 Duecanali DSP + Dante.
“We needed a lot of channels distribute along the exhibition, with five positions hidden from the visitors’ view,” said Alessandro Giuliani, AudioFactory’s R&D engineer “The Powersoft products were perfect to cover all the requirements of the project: high quality sound, low fan noise, adequate sound power, and overall remote control.”
Although sound power wasn’t the main challenge for this installation, the Powersoft amplifier platforms’ high voltage rail and low impedance driving capability were key to withstanding the 16-ohm D04 loudspeakers, which were used one per channel or in parallel (up to six per channel) according to the installation requirements.
“After the mounting phase we really appreciated setting up the system through the use of Powersoft’s ArmonìaPlus software, which allows us to tune the system smartly and quickly while walking through the exhibition path in the company of the composer and director,” explained Giuliani. “Dividing the exhibition in areas with ArmonìaPlus groups meant we could easily apply a custom EQ and level setup for each zone.”
