Every word to every seat at KwaSizabantu Mission

KwaSizabantu Mission sits in the hills of KwaZulu-Natal, between Greytown and KwaDukuza. Rev. Erlo Stegen founded it in 1970, and its Zulu name means “the place where people are helped”. It has grown into one of the largest mission stations in Africa, with its own schools, farms, community radio station and centres in several countries.

The auditorium is where the mission gathers. Sunday services are held there and streamed live. Twice a year, in the July and December holidays, youth conferences fill it with thousands of children and teenagers. Every two years the Ministers’ Conference brings together preachers from more than 50 denominations and organisations, from South Africa and abroad. The mission’s choirs and brass band perform there too.

The auditorium seats 8,000 people across a wide floor and galleries, under a timber roof. For decades, speech was its problem. In a room this big, sound from the front reaches the back late and mixed with echoes off the walls and roof. A sermon that was clear in the front rows blurred into the room further back.

Services at KwaSizabantu are built around preaching, so the brief was simple: every listener, in every seat, should understand every word. That meant a clearer system, not a louder one.

We built an acoustic model of the auditorium before choosing a system. It showed where sound had to go and where it had to be kept away from. From it we designed a d&b audiotechnik T-Series line array system. A line array is a column of speaker cabinets, each angled so that sound is aimed at the seats and kept off the walls and roof. Listeners hear more of the speaker and less of the room, even in the furthest gallery.

The cabinets were made in a custom white finish to sit quietly against the building. They hang from rigging points we planned around the roof structure. We then tuned the system in the room: we time-aligned it, so sound from every cabinet arrives at each seat together, and adjusted its tone for speech.

Behind the speakers, audio runs over a Dante network (audio carried over standard network cable), and Q-SYS handles processing and control. The mission’s team can run the whole system from one place, and it behaves the same way every service. Sennheiser EW-DX digital wireless microphones give the people on stage a clean, reliable signal from the moment they speak.

The system was commissioned in December 2025, and the speech problems the auditorium lived with for decades are gone. From the front row to the furthest gallery, the congregation hears the preaching clearly and naturally, without it being loud.

That clarity matters most on the mission’s biggest days, when conferences fill the room with young people and visiting ministers, and every seat needs to hear the same message.
