A Harman BSS Audio Soundweb London system has been fitted to manage 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.
Playback is all through JBL loudspeakers. In the main hall eight JBL Control 29AV-1’s are driven by Crown XLS 1000 amplifiers, while two compact JBL Control 1 Pro loudspeakers, powered by Crown MA135 mixer amps, act as monitors for the speaker’s table.
In each of the six classrooms are four JBL Control 28 driven by a Crown XLS 1000 and two JBL Control 1 Pro operating with a Crown 135MA amplifier, as monitor speakers. Finally, in each of the 28 small classrooms either two or four JBL Control 25’s can be found — in all cases powered by a Crown XLS 1000 amplifier — with a pair of JBL Control 1 Pro, powered by a Crown 135MA, serving as monitors. Equalization of the large lecture hall and six classrooms has been carried out digitally in the Soundweb London processors, which also handle the automatic mixing of all signals and delay lines.
The six 150-seat classrooms share video and audio signals with the main hall through a central node with a video matrix, and by a Soundweb London BLU link ring consisting of six BSS Audio BLU-100 and six BLU-800 processors, with two BSS Audio BLU-BIB (8-input expander) and BLU-BOB (8-channel output expander) increasing the I/O capability.
The Soundweb London BLU-800 in the main hall shares audio with a Soundcraft Compact 16 via a CobraNet card so that all mic inputs normally handled automatically by the Soundweb London processor can 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.
