As Lorde takes to the global stage for her highly anticipated "Ultrasound World Tour," traversing multiple continents and a vast array of venues, the production behind her live performances is a masterclass in modern audio engineering. Navigating the unpredictable variables of international touring requires more than just high-end gear; it demands a meticulously designed sonic ecosystem.
At the helm of this auditory voyage are Front of House (FOH) Engineer Philip J. Harvey and Monitor Engineer Kevin Glendinning. Together, they have forged a streamlined, resilient, and remarkably transparent audio chain. By heavily relying on industry-leading solutions from DPA Microphones and Wisycom, the production team ensures that Lorde’s dynamic performances—ranging from fragile, intimate vocal whispers to commanding, full-voiced crescendos—translate with pristine clarity to audiences worldwide.
Main Facts: The Anatomy of a Minimalist, High-Fidelity Touring Rig
The sonic architecture of the "Ultrasound World Tour" is defined by a paradox: a massive, arena-filling sound driven by an intentionally minimalist stage setup. Unlike traditional rock or pop productions that feature sprawling backlines of acoustic drums, guitar amplifiers, and extensive percussive setups, Lorde’s current live show leans heavily into synthesizers and direct inputs (DIs).
This streamlined aesthetic drastically reduces stage bleed and lowers the overall microphone count, placing an immense amount of responsibility on the few open mics on stage.
- The Vocal Chain: FOH engineer Philip J. Harvey relies exclusively on the DPA d:facto 4018VL capsule for Lorde’s primary lead vocal, as well as for the three backing vocal microphones on stage. This minimalist configuration means that just four microphones capture the entirety of the vocal performance.
- The Wireless Infrastructure: Monitor engineer Kevin Glendinning utilizes a unified Wisycom ecosystem for all in-ear monitoring (IEM). The system is built around Wisycom MPR50 beltpacks, MTK transmitters, MFL optical links, and a CSI16T combiner, outfitting every member of the band and crew with the exact same high-performance platform.
- RF Architecture: Designed in collaboration with RF specialist Stacey Handley, the wireless distribution network incorporates a fiber-linked RF distribution system to accommodate Lorde’s dynamic stage choreography, which includes a performance segment deep within the audience area at the Front of House position.
Chronology: Evolution of the Tour’s Sound and Engineering Choices
The sonic identity of the "Ultrasound World Tour" did not happen overnight; it is the culmination of years of iterative testing, trusted partnerships, and technological refinement on the road.
The Foundation: The "Melodrama" Era and Beyond
Philip J. Harvey’s relationship with Lorde spans more than a decade, giving him a deep understanding of her vocal delivery and artistic trajectory. The journey with DPA Microphones began in earnest during the Melodrama tour cycle. Searching for a microphone that could accurately represent the artist’s dynamic range without introducing artificial coloration or handling noise, Harvey discovered the DPA d:facto 4018VL capsule. It has remained a permanent fixture of the vocal chain ever since.
Scaling Up: Meeting International RF Challenges
As Lorde’s touring footprint expanded into larger arenas and more complex international markets, monitor engineer Kevin Glendinning faced the perpetual challenge of congested and unpredictable radio frequency (RF) environments. Transitioning the entire touring party—musicians and crew alike—to the Wisycom platform solved numerous logistical and technical hurdles. The wideband capabilities of the Wisycom hardware eliminated the need to swap out regional frequency-specific gear when crossing borders, allowing the crew to simply adjust frequencies and proceed seamlessly.
Integrating the Audience Experience
A crucial milestone in the tour’s preparation was solving the spatial audio challenges posed by Lorde’s stage blocking. Because the artist performs a portion of the show away from the main stage—specifically at the FOH position surrounded by thousands of fans—standard wireless transmission would typically suffer from dropouts or interference. The implementation of the Wisycom MFL RF-over-fiber system bridged this physical gap, extending flawless coverage into the heart of the audience and ensuring uninterrupted communication between the artist and the monitor world.
Supporting Data & Technical Specifications
To truly understand how the "Ultrasound World Tour" achieves its signature sound, one must examine the specific technical attributes of the hardware chosen by Harvey and Glendinning.
DPA d:facto 4018VL Capsule: Precision at the Source
The d:facto 4018VL (Very Linear) capsule is renowned in professional audio circles for bridging the gap between studio-grade condenser performance and the rugged durability required for live stages.
- Frequency Response: It offers an extremely smooth and linear off-axis response. Unlike traditional dynamic live mics that color sound as the source moves off-center, the 4018VL maintains tonal accuracy. This means that even with inevitable stage bleed from synths or crowd noise entering the vocal mics, the resulting mix remains natural and unmuddy.
- Dynamic Handling: Capable of handling extremely high SPLs (Sound Pressure Levels), the capsule effortlessly manages Lorde’s wide vocal spectrum—capturing the delicate intimacy of whispered verses just as clearly as high-energy, belted choruses.
Wisycom Wireless Ecosystem: Transparency and Low Noise Floor
Kevin Glendinning’s reliance on Wisycom is rooted in the platform’s superior audio fidelity and robust hardware design.
- Noise Floor: Wisycom systems are celebrated for having one of the lowest noise floors in the wireless industry, providing an exceptionally clean signal path that mimics a wired connection.
- Wideband Tuning: The hardware covers a broad spectrum of frequencies, making global frequency coordination significantly faster and more reliable.

Official Responses: Insights from the Engineering Team
Both Philip J. Harvey and Kevin Glendinning emphasize that successful live touring relies heavily on gear reliability, manufacturer support, and meticulous system design.
Reflecting on the vocal chain, Philip J. Harvey notes:
"We’ve been using the DPA d:facto 4018VL capsule since the ‘Melodrama’ tour. To me, it’s the most natural-sounding microphone out there. Whether it’s a whisper or a full-on scream, the d:facto captures everything with incredible detail and consistency… When you start with a microphone that sounds this good, everything else falls into place. It gives you confidence, and that translates directly to the audience experience."
Harvey also highlights the operational benefits of the mic’s off-axis rejection:
"Even when there’s bleed from other elements, it still sounds natural. That’s a huge advantage compared to other mics where off-axis coloration can become a problem. What you hear is what you get, and that makes mixing so much easier."
On the monitor and RF side, Kevin Glendinning speaks to the importance of standardizing the touring party’s in-ear monitoring experience:
"All our in-ear monitoring runs through Wisycom MPR50 beltpacks, MTK transmitters, MFL optical link, and a CSI16T combiner. We’ve outfitted everyone, from the band to crew members, with the same system. Consistency is key."
Discussing the durability and performance of the hardware, Glendinning adds:
"These beltpacks get dropped, sweated on, you name it. But they just keep going. You can’t compromise on build quality when you’re handing gear to artists every night… At the end of the day, everything I do is shaped by what comes through that belt-pack. If the transmission isn’t right, none of the upstream work matters. With Wisycom, I know the final result will sound exactly how it should."
Furthermore, Glendinning credits the collaborative nature of the production design:
"Being able to pick up the phone and get support or custom solutions quickly makes a huge difference." He specifically acknowledges RF specialist Stacey Handley for engineering the overarching system architecture that allows the complex fiber-linked RF distribution to run without a hitch.
