Hi‑Tech Audio Video Systems Pvt Ltd recently announced an exclusive distribution agreement with Outline, strengthening India’s professional live sound landscape. As the country’s live event calendar continues to grow, spanning international artist tours, IPL‑scale productions, large‑format weddings and major corporate events, the demand for systems capable of delivering concert‑grade performance to audiences of tens of thousands is rising sharply. In response, Hi‑Tech identified Outline’s GTO and GTO C‑12 line array systems as a natural choice for supporting India’s largest and most demanding live productions.

That appeal extends well beyond India. The GTO Series’ global popularity and proven performance were recently on display at the Luke Combs stadium show, highlighting the system’s ability to deliver scale, power and precision for world‑class international tours.

Outline announced that Special Event Services (SES), deployed its Outline GTO line-array system for Luke Combs' 2026 US stadium tour. The production opened on March 21 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 was 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 oversaw the expansion of the production from arenas to full-scale stadium environments, coordinating the integration of advanced audio and visual technologies across all of Luke's tours - including the 2026 run and subsequent international dates.

The tour featured 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 was handled via dual Outline Newton FPGA processors, ensuring precise optimisation, routing, and consistency across every venue.

This production was 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 required uniform coverage, tonal consistency, and intelligibility for every listener - including those seated in the most distant sections of NFL stadiums.

On April 25, at Ohio Stadium in Columbus, the tour reached a milestone that underlines the scale of the production: 97,367 fans attended the show, breaking the venue's all-time concert attendance record, which had stood since a Pink Floyd concert in 1994.

"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 - all long-time members of Luke Combs' touring team.

Lewis, who steps into the booth at every show with a system he knows and trusts, has been unequivocal in his assessment of the GTO: "This PA is stupid good. There are a lot of good-sounding boxes out there, but this one smokes the rest. I've never wished I had more."

The system's performance at distance is one of its most remarked-upon qualities. "From the 400 section - probably 120 feet above the stage - this Outline GTO PA continues to amaze me," Lewis adds. "If I had to make an educated guess, I'd say this was 400-450 feet from the auxiliary hang, and you can hear everything. You owe it to yourself to get in front of this product."

For Lewis, the verdict is simple: "All I can say to any engineer that asks - or doesn't - is that you owe it to yourself to hear this rig. Every guest engineer we've had on it agrees that it's hands down the best PA they've mixed on."
