Pan Intellecom delivers three projects in one at the largest convention centre in Goa. Reece Webb reports.
Located in Goa, the ONGC Convention Centre is the region’s newest and largest convention centre. Spanning three buildings and four floors, the campus features a 5,000-seater auditorium; exhibition hall; and Management Development Facility (MDF) with classrooms, conference rooms and a 120-seater multipurpose hall.
Long seen as a tourism hub without a permanent exhibition venue, Goa is now changing. Having hosted India Energy Week 2024 in temporary structures, ONGC set out to deliver a permanent facility in time for
the 2026 edition, appointing Pan Intellecom to design and deliver the AV systems across all three buildings. A remote site and compressed timeline meant that would be no small feat.
Project Management Consultant Engineers India Limited (EIL) created a tender for the convention centre and the MDF projects. Pan Intellecom entered the process with previous experience on ONGC projects and was brought on board to deliver both projects through competitive bidding in March 2025. Ranbir Singh, director, Pan Intellecom, explains: “ONGC wanted to make a world-class facility for domestic and international events. They wanted a state-of-the-art auditorium equipped with advanced technology that event management companies could operate. The primary objective was to make the world-class convention centre and to develop the MDF from there. This is a space where ONGC can send top level executives to get management, safety, and operational training. The objective of the MDF building was to have the best training environment. If a lecturer walks in, the system should require no technician, just easy to use, best-in-class technology.”
Jewel in the crown
The star of the show is the 5,000-seater auditorium, a massive event space stretching across four floors. Pan Intellecom delivered a BGM and PA system for the auditorium, installing 450 QSC ceiling speakers which are integrated with a network-based QSC paging station.
Spanning approximately 90m in length, 50m in width, with a ceiling height of 22m, the ONGC Convention Centre Goa auditorium is designed to host a wide spectrum of events, ranging from corporate conferences to large-scale musical performances. “The system is integrated with the fire alarm. If an evacuation is triggered, the BGM/PA system links directly with the fire alarm system,” says Ranbir.
A defining feature of the space is one of the world’s largest movable partitions, measuring 50m by 22m, allowing the auditorium to be seamlessly divided into two independent venues capable of hosting parallel seminars or conferences simultaneously.
To complement this flexibility, the audio system has been designed with multiple presets, enabling seamless adaptation to varying audience sizes and room configurations, ensuring consistent coverage, clarity, and performance across all operating modes.
Dominating the space is a Christie LED videowall with a 4mm pixel pitch, measuring 30m x 8.64m. Offering 8K resolution, it allows the client to show 8K content, two 4K content streams, or custom layouts using the tvONE Calico Pro videowall processor. Ranbir says: “The screen can be clearly seen from 75m away. The viewing distance for presentations and video is optimal but isn’t perfect for reading text. To address this, we have installed repeater panels, five Samsung 98-in displays on the second-floor balcony as well as four 75-in Samsung displays on the ground floor balcony for the audience.”
Pan Intellecom supplied two Christie E600 LED controllers to control the videowall which are connected to a tvONE Calico processor with eight 4K inputs and four 4K outputs. The auditorium’s beating heart is a Q-SYS control system, bringing all systems onto a single network for maximum flexibility and minimal technician involvement.
“All of this is connected to the network through the Q-SYS ecosystem,” says Ranbir. “The entire convention centre runs on the platform with Cores, QSC amplifiers, NV21 encoders and decoders, all of which are I/O integrated.
“The system is driven by Q-SYS Core X10 processors. We have installed two in the server room, one primary and one redundant.” Eight Lumens VCTR61 cameras are installed throughout the auditorium, featuring AI tracking and 30x zoom. Pan Intellecom supplied a network joystick controller to manually control the cameras and created camera presets via QSC for the in-room touchpanels so that users can switch the view easily.
Two podiums are available in the auditorium with BYOD functionality, complete with dedicated PCs in the server room for playing content. For audio, Pan Intellecom supplied a TW Audio loudspeaker system. At the front of the auditorium are eight TW Audio line array clusters. The left and right arrays feature a line array of 16 Vera 36 loudspeakers with two subwoofer clusters of seven Vera S 33 subwoofers on each side. In the centre, there is one cluster of 16 Vera 36 loudspeakers and five Vera S 33 subwoofers.
“TW Audio stage monitors, front fills, and front subwoofers have been deployed to ensure consistent balance and impact across the performance area,” explains Ranbir. “To address coverage uniformity in the upper tiers, delay speakers have been positioned at the second balcony and ground floor balcony levels.
“The system has been engineered to achieve performance targets across the audience area from 100 Hz to 10 kHz, delivering an average SPL of 94.79 dB(A) with a standard deviation of 1.37 dB, ensuring uniformity. The measured levels range from a minimum of 88.04 dB to a maximum of 98.86 dB, maintaining clarity, intelligibility, and consistent listener experience across all seating zones.”
The integrator also supplied Sennheiser microphones, running primarily on the EW-D wireless system. The system includes
lapel, headworn, handheld, and gooseneck microphones. Instrument microphones, including a drum kit microphone, cover all bases for bands and performers in the auditorium. Ranbir says: “The auditorium was primarily designed for speech and conferencing. It runs through an Allen & Heath SQ7 mixer on Dante. Networked stage boxes on either side allow microphones to be patched in.”
The convention centre also has multiple green rooms operating with preview displays on Q-SYS decoders, so that upcoming presenters can keep tabs on proceedings within the auditorium.
For interpretation, Pan Intellecom supplied Televic Unite 750 wireless transmitters and headphones with eight Televic access points throughout the auditorium. Ranbir explains: “If there is an international conference going on with multiple delegates in various languages, we can accommodate that. We also have eight Televic interpreter consoles in the interpreter room The auditorium has a complete solution with the necessary redundancy, including analogue paths in case Dante fails.”
Executive decisions
Moving to the first floor of the convention centre, Pan Intellecom installed a technology-rich CEO conference room, designed for high-level executive meetings. This space features a CEO round table with 53 seats.
The integrator supplied a 6m x 3.3m Samsung COB LED videowall as the main display, offering 4K capability, as well as four 98-in 4K side displays. Pan Intellecom supplied a dedicated display for the chairman: an Arthur Holm 17-in 4K retractable monitor, capable of annotation and highlighting for executive use.
Fifty-three Televic fully retractable gooseneck microphones were installed, using Arthur Holm microphone lifts to discreetly hide the microphones when not in use. Providing a true senior level experience, Pan Intellecom also supplied Televic name plates which can be electronically configured for each individual participant and meeting.
A Televic interpretation system is also in place with 50 transmitters and two access points. For content management, a tvONE CorioMaster C3 multiviewer presenter drives presentation across the Samsung displays and videowall.
For videoconferencing, a Poly G7500 codec has been deployed in conjunction with six QSC NC-20x60 PTZ cameras. The multi-camera setup enables dynamic framing and seamless switching between viewpoints, ensuring an engaging and equitable experience for remote participants.
Ranbir explains: “This is the most advanced conference room in the entire facility. The CorioMaster distributes multiview content to both the displays and the videowall. We also installed ten cable management points, which can be controlled through a dedicated server or be used in a BYOD setup. A Barco C10 ClickShare enables wireless presentation, while two Q-SYS 10-in touch- panels were installed for control.”
Pan Intellecom also delivered a bilateral talks room. This is a more intimate, private space for confidential conversations. Ranbir says: “We installed a Samsung LED 1.5mm COB display with
a 25-unit Televic wireless interpretation system with Sennheiser wireless lapel microphones for full flexibility.”
The second-floor AV control room houses three racks containing Dynacord amplifiers, which power the TW Audio line arrays in the auditorium, alongside Q-SYS Core processors. There are four racks in the auditorium, with three located on the top floor and another located next to the stage.
This stage-side rack allowed Pan Intellecom to use shorter cable runs for the auditorium’s video systems. Netgear PoE++ switches support the network infrastructure across the facility.
The second building on site consists of a 120m x 60m exhibition hall. Pan Intellecom was tasked with delivering a BGM/PA system consisting of 53 surface mount speakers which were installed on the ceiling of the exhibition hall for BGM and announcements.
“The client wanted the management development facility to be the prime focus as that is what ONGC is going to use heavily. The conference centre was built not just for them, but
for Goa too,” says Ranbir.
Trained to succeed
The final building delivered by Pan Intellecom is the Management Development Facility (MDF), a comprehensive learning environment for management executives and trainees for advanced technical training.
As in the auditorium, the facility’s BGM system is integrated with the fire alarm, with 200 QSC speakers across both floors. “The building can be localised,” explains Ranbir. “There are dining halls, VIP halls, and we have Bluetooth wall plates and 5-in touchpanels where you can control the audio.”
On the first floor, the facility features eight syndicate rooms, each seating eight to ten people and equipped with three cable managers for content sharing, a QSC camera, and an 85-in Samsung interactive display. Audio is handled by a Sennheiser TCC2 microphone.
In four of the facility’s syndicate rooms a divisible partition is included to bring the spaces together for larger events, creating two larger rooms. This is enabled by a separate Q-SYS Core DSP.
There are also eight classrooms, each equipped with a 135-in Samsung COB LED videowall. Ranbir continues: “The videowall ensures clear text visibility for everyone in the room. We also installed two cameras, one for the presenter and one for the audience, tracked via Sennheiser ceiling microphones in each space. The microphones are integrated with a voice lift system to ensure even audio coverage.”
Eight digital podiums have been supplied, connected to the QSC encoders. The entire building is running on the Q-SYS system, with all classrooms and syndicate rooms linked via encoders.
“There are three classrooms that can be merged as one,” adds Ranbir. “We have two collapsible partitions with another DSP from QSC.”
On the ground floor of the MDF facility, a 120-seat auditorium is designed for seminars and multipurpose events. It features two Samsung IAB series COB videowalls, six Sennheiser ceiling microphones with voice lift for full coverage, two digital podiums with touch controllers, and 20 ceiling speakers with ceiling subs.
The final space in the facility is the executive conference room, which features a 1.5mm COB Samsung 150-in videowall, two Sennheiser ceiling microphones, five cable managers, and three QSC cameras.
Ranbir continues: “The system is fully scalable and modular. If they want to shift any input anywhere, they can do it. If they want to add another room or scale down, then they can do it. It’s the most modern training building that ONGC has built.”
Time proved to be the biggest challenge during the installation process. Facing a looming deadline brought on by India Energy Week, Pan Intellecom had only 35 days to deliver the entire project, working in a hectic, dusty environment to complete the project on time to the highest possible standard.
Ranbir says: “This was three projects in one, delivered in 35 days. We installed the videowall in a dusty environment and had to put a lot of equipment in place while dust was still present. We took protective measures, including wrapping the products after installation. They remained covered for a period of time before being unwrapped, tested and commissioned. We had 30 people on site working day and night.”
To make matters more complicated, the work site itself was also in a remote location, meaning that sourcing critical components was constrained due to accessibility issues.
Ranbir adds: “Goa has a fourmonth rain season, reducing the 13-month project timeline to just eight months, as construction had to pause.”
Pan Intellecom worked closely with TW Audio on the design and execution of the system on site, as well as the QSC team due to the size of the deployment.
“The Q-SYS software was pre-programmed before getting to site,” says Ranbir. “With control programs completed ahead of India Energy Week, commissioning was much smoother. We also provided dedicated to ensure theteam could operate the system during the event.
“This marks the first edition of India Energy Week which was conducted with a fully fixed AV installation. The rental operations team initially encountered challenges due to the shift from familiar rental systems to a fully integrated fixed AV infrastructure. We supported them through system familiarisation and operational assistance, ensuring seamless execution across all event spaces during the event.”
With the event concluded and the project complete, Pan Intellecom was able to beat the odds and deliver a project of a massive scale within an uncompromising deadline. Ranbir explains: “When I first reached site, the scale and the dusty conditions made the installation feel almost impossible. But projects like these are built on the client’s trust, support of the OEMs, and that is what pushes you forward. It becomes less about the challenges and more about the responsibility. For us, this wasn’t just another project it was something bigger, and we knew we had to deliver.”
