Outline GTO returns with Special Event Services for Luke Combs’ 2026 US stadium tour featuring the largest Outline system ever deployed in the US

USA – Outline announces that Special Event Services (SES), a leading US event production company specialising in large-scale live audio and staging, will once again deploy its Outline GTO line-array system for Luke Combs’ forthcoming 2026 US stadium tour. The production will open on 21 March at Allegiant Stadium, marking the fourth consecutive year that SES has provided Outline’s flagship system for one of country music’s most successful touring productions.

A central figure in the continued growth of Combs’ live production is Michael Brammer, chief strategy officer of Concert Stuff Group (CSG) and long-time strategic partner for Luke Combs’ touring operations. Through SES and CSG, Brammer has overseen the expansion of the production from arenas to full-scale stadium environments, co-ordinating the integration of advanced audio and visual technologies across all of Luke’s Tours, including the 2026 run and subsequent international dates.

The tour will feature a comprehensive Outline deployment, combining GTO main arrays with GTO-LOW, Mantas 28, GTO C-12, LAB21-HS subwoofers and LIPF-082 front-fill loudspeakers. System control at front of house will be handled via dual Outline Newton FPGA processors, ensuring precise optimisation, routing and consistency across every venue.

This production represents the largest Outline system ever deployed in the US, configured to support a full in-the-round stage positioned at the centre of the field. This demanding 360-degree geometry requires uniform coverage, tonal consistency and intelligibility for every listener, including those seated in the most distant sections of NFL stadiums.

“Getting to watch Luke’s stadium show grow into a true in-the-round production has been incredibly personal for our team,” said Michael Brammer of concert stuff group. “Operationally, it forces all of us to think differently about how we move, how we build and how we communicate as one team. On the audio side, continuing to deploy our GTO systems on a tour of this scale has been something I’m especially proud of. In a 360-degree stadium environment, you’re chasing clarity, power and consistency for every seat while managing reflections, delay and phase in a space that was never designed for perfect symmetry. When it all locks in and you stand in the centre of that field surrounded by fans in every direction, you realise the challenge is exactly what makes it so rewarding.”

System design is led by sound designers Jason Farah and Joe Lefebvre, who are utilising Outline’s OpenArray 3D simulation software to model and optimise performance for each venue. They are joined by front of house engineer Todd Lewis, they are all long-time members of Luke Combs’ touring team.
