Two and a half million people are believed to have flocked to the 2016 World Youth Day (WYD), which is billed as the biggest event in the world. The international Catholic event focuses on faith and youth, and this year took place at two sites in Kraków and Brzegi.
Pope Francis addressed large gatherings of pilgrims and given the scale of the event, the pressure on providing a suitable public address system and pristine signal delivery to all worshippers across the vast spaces was immense.
Considering the large number of sound towers and receivers deployed — and vast distances between them (the furthest was located almost 2km from FOH) — the only solution was to use fibre. Optocore and its OEM associate, BroaMan uniquely have this capability, and they set up a fully-redundant optical fibre network using the advanced, protocol-independent tools.
Both the principal sound rental companies — GigantSound-Letus and GMB Pro Sound — were charged with sourcing the inventory to implement this. They relied heavily on large multi-node redundant Optocore ring networks for the two main sites, Błonia Park in Kraków, which holds 600,000, and the nearby village of Brzegi, where the site could accommodate 2.5-3 million people. The latter location saw the biggest deployment of technical gear ever put out for a single event, according to Gigant’s Jurek Taborowski.
The person responsible for specifying the BroaMan / Optocore solution was Marek Kotomski, coordinator from the WYD Organising Committee and co-designer of the fibre infrastructure in Kraków.
In total, some 160 devices from the German company were deployed, with a large number of interfaces provided respectively by French partners, Lumière & Son and GB4D.
Meanwhile, another Polish company, 4Vision, was contracted to install and maintain these systems, with onsite support throughout from the Optocore technicians. 4Vision also had to manage the timetable in what proved to be a fast fit project, with challenging deadlines.
Brought in by the WYD Organising Committee, the 4Vision team received training from Optocore before taking delivery of the pre-configured rack systems at the two French bases. Stated Pawel Fila, who supervised the technical installation, “Aside from the distances we needed to cover, the advantages of using Optocore was that the system was so simple for installation and control.”
CAMPUS MISERICORDIAE, BRZEGI
The Brzegi Campus Misericordiae site comprised 67 audio towers (13 intercom equipped), 28 video walls and four rings; in total 84 cases of equipment were shipped to site.
Lumière & Son had designed and configured the set-up for delivery to Gigant Sound, constructing an Optocore plug and play system at their headquarters in Paris before inviting five 4Vision technicians to receive system induction and training. This enabled the Polish company to create three Optocore rings, along with 18 BroaMan Mux22 and two Route66, all supplied by Lumière & Son.
Each of the audio and video towers contained a single Optocore device providing analog out, AES out and LAN Ethernet to Powersoft amps, which in turn drove Outline loudspeakers. At FOH the system received direct inputs from the Yamaha mixing desk via Optocore’s Y3R-TP interface card.
In total 108 Optocore devices were deployed. The three rings were purpose-configured by Lumiere to meet the specific requirements; some racks containing X6R-FX devices only, some with BroaMan Mux22, Route66 and X6R-TP, while some were plugged with DD32R-FX interfaces and older X6P.
In addition three dedicated BroaMan systems were assembled — one ring with 10 Mux22 interfaces and two in a star topology, with a Route66 and four Mux22 in each. All devices provided program feed in HD-SDI format to the 27 LED screens supplied by Supervision Poland, and both BroaMan and Optocore systems used singlemode fibre infrastructure built especially for the event.
With this enormous requirement Lumière & Son also sourced equipment from fellow French-based Optocore houses, GB4D and De Préférence. In terms of scale Lumière & Son president, Pierre Heyligen, confirmed, “This project used more devices than for COP 21 [Climate Change Conference] and [Grand opening of the new] Suez Canal — although required fewer channels.”
In addition to the Optocore / BroaMan deployment, GigantSound also delivered loudspeakers, amps, mixing desks and intercom to this destination.
