International Swimming Competition: deep mixing dive

German audio technology purveyor, Lawo, was living the life aquatic as the company partnered with the International Swimming Competition, which was held in Asia for the first time in the athletic event’s history. With over 600 of the world’s greatest swimming athletes gathering for the competition held in Singapore in 2025, Lawo was brought on board to meet the broadcasting technology demands for this global sporting event. To rise to the task of providing an official audio mix that met the standards of this renowned, international event, a leading national broadcaster decided to center the mix around Lawo’s mc²56 MkIII production console.

The audio production was handled from the broadcaster’s fully IP-based outside broadcast vehicle, where the 48-fader Lawo mc²56 MkIII serves as the core mixing console. To rise to the intensity of a live sports event and broadcast, a 16-fader mc²36 console was positioned as a standby mixer, ensuring full hardware and network redundancy for uninterrupted coverage.

Aquatic sports in particular throw up unique, and not to mention wet, acoustic challenges. This meant the audio team was required to synthesize multiple, specialized source types into a cohesive final mix. The console was used to balance dynamic elements crucial to the broadcast narrative, including comprehensive crowd ambience, feeds from multiple commentator positions, and the specialized capture provided by underwater microphones.

The mc²56 MkIII’s features — such as native support for immersive audio formats and integrated automix functions — were utilized to manage the complex, fast-moving audio environment. The system’s flexible configuration and advanced workflow tools, including rapid snapshot recall capabilities, allowed engineers to adapt the setup seamlessly between competition heats and finals, maintaining a consistent and professional output throughout the six-day event.

During all the dives and impressive front crawl swimming on display, the mixing console’s performance was underpinned with the Lawo A__UHD Core, a software-defined IP audio engine. Housed in a compact 1RU frame, this core provided substantial processing power, capable of delivering up to 1,024 DSP channels.

The deployment was clear evidence of the industry’s continued transition toward IP-centric infrastructure. The A__UHD Core provides ultra-low latency performance necessary for real-time mixing, and it supports essential broadcast standards including native RAVENNA/AES67 and SMPTE ST2110. Adherence to these protocols facilitates wide interoperability, allowing the system to communicate efficiently with other devices and networks within the venue’s wider broadcast infrastructure.

The A__UHD Core incorporates Lawo’s HOME functionality, designed to simplify the setup and management of IP signal paths, making complex network configuration more efficient for the operational team. In addition to redundancy measures, the system’s energy-efficient design is an important operational consideration for mobile production units.

The international aquatics event was held at the OCBC Aquatic Centre, a world-class venue for swimming, diving, and more. It forms a part of the Singapore Sports Hub, a 35-hectare public-private partnership in the huge sports and recreation district in Kallang, Singapore. The Sports Hub was unveiled and opened to the Singaporean public in June 2014, and is well served by multiple modes of train travel and other transport. The sporting village was proposed by the Singapore parliament in 2001 with a view to replacing the ageing National Stadium.
