HARMAN’s BSS Audio Backbone Networks Multiple Lecuture Halls at the University of Torino

TURIN, Italy — In order to allow lessons to be streamed via the Internet at the University of Torino in Italy, integrator Leading Technologies srl (LTech) recently designed a technical AV infrastructure for more than 30 classrooms (and main assembly hall) in the Law & Political Science faculty. At the heart of the network is a complete HARMAN BSS Audio Soundweb London system, which allows for seamless management of the classroom’s audio and video control.  The facilities include six lecture rooms, each containing approximately 150 seats, 28 classrooms — and a grand assembly hall with 300 seats, which is also occasionally used to stage small concerts.

LTech chose to place the system on a BSS Audio Soundweb London network, with its proprietary BLU link digital audio bus, to provide a powerful and rock solid backbone. “Ourreal achievement was the integration of the Soundweb London audio signals with videoand our supportfor the designand programming of these systems. It was vitally important to haveaudio, videoandweb control all from asingle brand of product,” explained Mauro Lavazza, Project Manager for LTech.

Playback is all through JBL loudspeakers. In the main halleightJBL Control29AV-1’s, chosen for their extremely flat, high-fidelity performance, extended bandwidth and well-controlleddefined coverage, are driven byCrownXLS1000 amplifiers,while two compact JBL Control 1Pro loudspeakers, powered by Crown MA135 mixer amps, act as monitors forthe speaker’s table.

Ineach of the sixclassroomsare four JBLControl28driven by aCrownXLS1000 andtwo JBLControl 1 Pro operating with a Crown 135MA amplifier, asmonitorspeakers. Finally, ineach of the 28smallclassroomseither two or four JBLControl 25’s can be found — in all cases powered by a Crown XLS1000 amplifier — with a pair of JBL Control 1 Pro, powered by a Crown 135MA, serving asmonitors.Equalization of thelargelecture hallandsixclassroomshas been carried out digitally in the Soundweb London processors, which also handle the automatic mixingof all signals anddelay lines.

The six 150-seat classroomssharevideo and audio signalswiththe main hallthrough a central node with a video matrix, and by a Soundweb London BLU link ringconsisting of six BSS AudioBLU-100and six BLU-800 processors, withtwoBSS Audio BLU-BIB (8-input expander) and BLU-BOB (8-channel output expander) increasing the I/O capability.


TheSoundweb LondonBLU-800inthe main hallshares audio witha SoundcraftCompact 16via a CobraNetcardso that all mic inputsnormallyhandledautomatically by the Soundweb London processorcan be mixed in manual mode (plus analogue inputs during live concert performance).

In the smaller rooms, mic EQ is handled from a series of Soundcraft EPM-6 mixers. These have been specified throughout the 28 classrooms to handle mic mixing and computer signals.

In conclusion Mauro Lavazza stated, “This has been a successful integration which fully meets the client’s requirements. They were particularly enthusiasticabout the performanceof theSoundweb Londonprocessorsthat make up theheart of the system,for their flexibilityand ease of programming. Without having any previous experience of this platform they have immediately created complete autonomy in the managementand maintenance of their audio systems.”
