NJSM ProSound and d&b Audiotechnik Deliver Flawless Audio Across Ed Sheeran’s Historic Concerts in India and Bhutan

Ed Sheeran’s Mathematics World Tour concluded its India leg in February 2025, marking a significant milestone with the deployment of d&b audiotechnik’s KSL system. This tour not only showcased Sheeran’s musical prowess but also highlighted the capabilities of the KSL system in delivering consistent, high-quality sound across diverse venues and geographies.

Mumbai-based NJSM ProSound Pvt Ltd, a part of the SOUND.COM Group, supplied the KSL system for the tour; as the journey commenced with a historic performance on 24 January in Bhutan – with this being the country’s first-ever international concert – before traversing five major Indian cities and culminating in Delhi.

To navigate the logistical complexities of touring across the vast subcontinent, NJSM ProSound collaborated closely with d&b India’s Education & Application Support representative, Neil Lean. The tour adopted an end-on format – a stark contrast to the 360˚ in-the-round productions of previous legs; yet a strategic choice that not only simplified deployment and accommodated tight schedules, but also ensured optimal sound quality, from the stage to the farthest audience areas – all thanks to the KSL system’s lightweight design and cardioid performance.

The system configuration included main hangs of KSL8 and KSL12 cabinets (16 per side), 10 flown SL-Subs per side, and 24 ground-stacked SL-GSubs in an end-fire arrangement. Front-fills were managed by d&b’s V8 and V12 cabinets, with delays provided by KSL, XSL, and V-Series cabinets, tailored to each venue’s specific needs.

Transportation logistics posed significant challenges, given India’s expansive geography. Equipment arriving in the early morning had to be operational by 10 am. The KSL system’s integrated rigging solutions and dedicated dollies facilitated swift deployment and tuning at each site.

Neil Lean remarked, “The SL-Series’ cardioid pattern allowed us to open up the body of the system with no worries about feedback from the small body guitars Ed was using on stage. The best way to judge a touring PA is by how consistently it can deliver, show after show, and this system performed flawlessly throughout the tour. The production teams, including the representatives of AEG and its India partner, BookMyShow, were very happy with the quality the system delivered, and we had great comments on social media about how good the audio was in every city we visited.”

Ed Sheeran’s touring sound team — Simon Kemp at FOH and systems engineer Adam Wells — echoed the audience’s positive feedback, expressing their admiration not just for the exceptional audio quality but also for the commitment and professionalism of the local crew.

Warren D’Souza, Founder of SOUND.COM Group, concluded, “We delivered outstanding results, and it’s incredibly rewarding to have Simon and Adam share that sentiment.”
