Installed in a control room, the iDR system comprises three iDR-8 matrix mixers and iDR-in and iDR-out expander units providing a total of 32 inputs/outputs of DSP. The five rack units are networked to provide control of all the system parameters and routing matrix, programmed using iDR System Manager software. Control can be accessed directly from the units, via two PL-10 rotary fader panels - one located in the control room and the other in the auditorium’s sound booth - or from inside the auditorium from WiFi networked laptops loaded with PL-Client software, which enables the installer to create tailor made control parameters and virtual wallplates.
The flexible control methods enable the user to mix audio and select sources, such as CD, mics, videoconference, satellite and other feeds, from a variety of locations. The two PL-10 controllers are provided for those operators who prefer a physical control surface to engineer events, rather than computer software.
Grisby’s design specialist, Luigi Locorotondo, said:
“The iDR’s capacity is astounding – the potential of this system even exceeds the vast number of functions it is currently assigned. Moreover, the preset features mean that engineers benefit from more time to create, produce and mix live events.”
A specific requirement of the new system was that it could manage a large number of microphones. The iDR’s 'Automatic Mic Mixer’ mode in particular is a great benefit to the conferences that are regularly hosted at the venue, where several microphones can contribute to the mix. Microphones are only opened when they are being spoken into and the overall gain is reduced as more microphones are opened.
The venue has been architecturally designed - including acoustic treatment - to best suit any kind of sound. There is a multi-channel playback system, and a FOH PA system in LCR format, two main subwoofers, plus surround sound loudspeakers.
“Thanks to the iDR system we have made an important technical upgrade to our auditorium. It is my job to accommodate many different activities every day, and with the iDR system I have gained flexibility, quality in sound, and a decrease in set up times,” concludes G d’Annunzio University’s technical director, Marcello Di Nino.
