PCI over IP at Evangel Seminary
Providing religious tuition to students, the Evangel Seminary recently located to a new facility in Kowloon, Hong Kong. Commissioned to design and install AV technology throughout the four-level building, Prime Connections International (PCI) Holding Co Ltd undertook a full survey of the premises in addition to evaluating the events being held in the class and lecture rooms. Based on the client’s budget and requirements, the Solutions Team proposed a flexible, ease-of-use and cost-effective design adopting a QSC Q-Sys AV-over-IP network at its heart.
With seating capacity for 280 congregants, the ground-floor chapel is mainly used for worship services, combining spoken word with charismatic musical performances. A powerful, yet unobtrusive, loudspeaker system has been integrated into the room’s design, adopting L-Acoustics dual Syva wall-mounted cabinets augmented by dual 12-inch Syva Low subwoofers. Operating within a 60Hz – 20kHz frequency range, five X8 coaxial bass-reflex cabinets have been adopted into the chapel. While two are used as stage monitors, three are ceiling-mounted towards the rear of the room as delays to provide an even 100° axisymmetric directivity output. Amplification and DSP settings are maintained by two LA4X four-channel amplified controllers.
Delivering sermons from the lectern, the pastor is equipped with dual DPA 4098 gooseneck microphones. The singers and worship leaders draw upon Sennheiser ew300 G4 UHF wireless handheld mics in combination with Mipro headsets, while the musicians are equipped with a combination of Shure Beta SM57 and SM87 models. Stereo mixing conducted on an Allen & Heath SQ-6 48-channel console is also routed to the Q-Sys Core 510i Core processor for audio broadcast to other rooms in the seminary.
Enhanced with AV technology, a ground-floor lecture theatre is equipped with Shure MX418 gooseneck and Raxikol wireless handheld microphones together with Mackie Pro FX4 v2 mixers. Wall-mounted QSC AD-S802T column speakers provide intelligible reinforced speech in the ground-level student and first-level lecture rooms, in addition to an outdoor zone. Silence is broken in the library when a pre-recorded announcement from the programmed Q-Sys Core 510i reminds visitors that the room will shortly close. Powered by four QSC CXD8.4Q amplifiers, the seminary’s public address system comprises 32 QSC AD-C4T 4.5-inch ceiling and 16 QSC AD-S802T column speakers.
Connected to the Q-Sys Core 510i platform, a series of Visionary Solutions Duet encoders and decoders route a selection of HDMI signals over the Cat-6A network for broadcasting to a selection of 4K-ready LED displays. In addition to serving as localised inputs and outputs, nine Q-Sys I/O-8 Flex channel expanders provide signal distribution over the Q-LAN network via the Core 510i. The video-over-IP streaming solution allows live events taking place in the chapel or main lecture theatre to be transmitted and broadcast to other rooms during peak demand. Each channel is remotely configured via software as a mic/line input and controlled from Q-Sys TSC-80W wall-mounted and table-top touchscreens.
‘With events already scheduled, the project had to be completed within a tight time frame between semesters,’ explained PCI’s application manager, Wilson Wai. ‘It was a challenge to complete the fit-out in all the rooms together with the system programming, audio level adjustments and end user training within the eight-week period. The flexibility provided by the Q-Sys Core backbone together with the ease-of-use Q-Sys touchscreen control interface ensures that trained novices can both operate and control a sophisticated AV system that is future-proofed for many years.’
