Sydney Overseas Passenger Terminal installs Bosch Praesideo PA system
AUSTRALIA: Upon entering the cove bay into Australia's largest city, the heads of international cruise visitors are spinning in awe as they are greeted with views of the Sydney Opera House, Harbour Bridge and the city skyline. The three-storey Overseas Passenger Terminal is their interface between international waters, the large cruise liner they are on, and one of the most beautiful harbour cities in the world.
Following a total renovation of the OPT between 2014 and 2015, engineering consultant Umow Lai was called upon to design an effective public address solution that would ensure passengers would be processed quickly.
A Bosch Praesideo digital network PA system was selected as the audio solution for those arriving and departing Sydney via sea. Systems integrator CNG Systems installed a five-zone system in which the resultant loudspeakers optimise the ceiling heights and room spaces they serve.
Announcement desks on each level of the OPT combine Bosch PRS-CSR control stations, PRS-CSI call station interfaces and LBB-4432/00 keypads. Programmed and live announcements are amplified via PRS-1P500 single channel, PRS-2P250 2-channel and PRS-4P125 4-channel amplifiers to the loudspeaker network.
Incoming visitors walking down the ship gangplanks to the OPT are greeted by Bosch LH1-UC30E 30W two-way all-weather ABS horns. 'These models provide much higher intelligibility than standard horns,' confirmed CNG Systems manager Paul Corbett. 'This particular application required an extended frequency range and high sensitivity speaker solution to alert passengers to get their documents in order and join the correct queue.'
Elsewhere, the 4m ceilings in levels one and two are reinforced with equally spaced EV Evid C4.2 ceiling speakers, whilst the escalators are served by C8.2HC models. Bosch LBC3099 speakers have been added to back of house areas. A back of house ELV room combines a Bosch PRS NCO3 network controller and the Praesideo amplifiers, which creates the de-centralised network facilitating the five-zone daisy chain configurations. Fully programmed, the redundant network is also served by three channels of Shure ULXD4 wireless mic systems and a CD player.
A hearing loop has been installed on level two, whilst RF Systems promoting assistive listening are located on the levels above and below. 'Testing and commissioning the system was challenging,' confirmed Mr Corbett. 'We had to remain on site until after 3am on some evenings performing STI tests as there was continual construction taking place in this reverberant building. Once we had completed the tests, we were delighted with the results and the performance of the system. With the added functionality we have installed in the OPT, the building can now be used as a multi-functional space should the need arise.'
