A multifunctional space to host various types of events: from sports team training sessions to press conferences, conventions, concerts, and even village festivals. This is the goal behind the creation of the audio-video system in the Multipurpose Hall of the municipality of Salgareda, Treviso.
The system was completed in February 2023 by the system integrator Auditec, with design consultation from Prase Media Technologies. The technologies utilized include Atlona, Biamp, Epson, Muxlab, Netgear, Powersoft, Screenint, and Shure.
To ensure uniform audio coverage across the entire 800 square meters of space, a suspended ceiling diffusion configuration was chosen, creating a grid of 7 rows with 3 Biamp Community DP8B model speakers, featuring a 125° conical dispersion.
The sound distribution system is managed through the Tesira Forté DAN CI DSP, the core of the system that allows for various configurations and adapts the audio-video setup to the multipurpose nature of the hall.
For a press conference or convention, for example, with a speaker table facing an audience, Tesira enables adjustment of the audio for the front rows of speakers and the first rows of seating, gradually increasing the volume as one moves away from the speaker.
Tesira also allows for the division of audio in the hall in case different configurations are needed, providing more flexible management of the space. The BIAMP TEC1-S control panel can program and preset multiple audio scenarios based on the different uses of the hall.
The capabilities of the Tesira DSP go beyond audio processing and also allow integration with third-party devices, such as the two Epson projectors with 10,000 and 8,500 lumens installed in the multipurpose hall (EB-PU2010W and EB-PU1008B models), using two motorized screens with Screenint Major model casings as projection support.
The six configurations recalled by the TEC1-S panel also allow for cross-referencing of video signals depending on the selected scenario. Video processing is managed by an Atlona UHD matrix that, responding to commands sent by Tesira, cross-references the incoming and outgoing video signals based on the desired scenarios.
“The use of Tesira as a control system allows for the prediction of the power on and power off sequences for all devices. In this installation, Tesira represents the heart of the entire system as both the DSP and the audio and user interface,” commented Luigi Schiavone and Sonny Laurano, Application Engineers at Prase Media Technologies.
In terms of microphones, a Dante audio interface was added to the second partition of the hall, complementing the audio inputs of the Tesira DSP and allowing for the use of a wireless system in line with the project’s flexibility. The choice fell on a kit with a handheld transmitter and receiver, the Shure BLX2/SM58, ensuring complete intelligibility in any configuration.
The audio distribution over IP functions of the Tesira DSP via Dante allow for flexible and rapid utilization and modification of the audio distribution over IP based on the needs of the event.
In addition to the Shure BLX2/SM58 kit, the installation is completed with Shure CVG18DRS-B/C tabletop gooseneck models, used for front-facing conferences.
