Moving the orchestra outdoors

Capturing an orchestra is a precise exercise. In a controlled studio environment, microphone placement, acoustics and signal chain can be carefully managed to preserve the balance between individual instruments and the collective sound. Move the same ensemble into an open-air setting and those variables begin to shift, often in ways that are difficult to control.

Outdoor performance introduces a set of constraints that don’t exist inside the studio. Wind, scale and environmental noise all affect how sound is captured, while audience expectations remain unchanged. For engineers, the task becomes one of maintaining consistency, ensuring that the character of each instrument is preserved even when the environment is working against it.

This challenge has become central to the workflow developed at Firdaus Studio in Dubai’s Expo City. Leading the studio’s technical approach is Navneeth Balachanderan, whose background spans 15 years of live shows, studio sessions and collaborations with some of the world’s biggest artists.

Designed as an orchestral recording and production facility, the studio supports a range of content including film scores, vocal sessions and large ensemble recording. But beyond the studio, Firdaus also serves as a creative hub and the home of the Firdaus Orchestra, an all-female ensemble celebrating musical diversity. Balachanderan’s job has been to create a workflow designed to translate studio expectations into live performance contexts, where control is more limited and system reliability becomes critical. The choice of microphone is paramount.

Inside the studio, its impressive arsenal of Neumann microphones, ranging from the iconic U 87 and U 67, to the KM 184, TLM 193, M149, 103, 107 and the latest MT 48, have become essential tools for Balachanderan, where they’re embedded across the workflow. “For me, Neumann microphones are musical by nature,” he explains. “They bring out the true tone of any instrument – whether it’s a cello or a guitar – with minimal processing required. They don’t just sound technically correct, they sound beautiful.”

Moving the orchestra outdoors for live performances though creates a different set of requirements. Firdaus Orchestra concerts are typically held at Al Wasl Plaza in Expo City Dubai – a venue that experiences high wind speeds and creates obstacles for sound engineers trying to preserve the sonic integrity of orchestral instruments. Here, maintaining tonal integrity across strings, brass and woodwind sections presents a specific challenge.

“In a live outdoor venue with heavy winds, clarity is usually the first thing to go,” Balachanderan explains. For orchestral instruments, attempts to correct this at the mixing stage can introduce further issues. Low-frequency content is fundamental to instruments such as cello and double bass, and aggressive filtering can reduce both presence and musicality. “You cannot take a lot of low end out of a bass or a cello,” he notes. “When you start doing that, you’re going to lose the quality of sound of the instrument.”

His solution to mitigating these issues has been to employ the German manufacturer’s MCM 114 miniature clip microphone for orchestral instruments – especially cellos, double basses, woodwinds, brass and qanun. Supplied by Venuetech, the mics were first trialled by Agora LLC during the recent Layali Firdaus live performances at Al Wasl.

Balachanderan reports that this configuration has enabled a more stable and repeatable capture of instruments in outdoor settings, with less reliance on corrective EQ during mixing. He describes the resulting sound as flatter and more natural, closer to what would be expected in a controlled recording environment, allowing the overall mix to retain greater detail and balance.

One of the most underrated challenges in live sound is microphone stability and setup. In fast-paced, high-stakes environments, every second counts. “The clips are one of my favourite parts,” Balachanderan says. “You simply clip the mic on and it doesn’t move – they stay put.” In fast-paced production environments, this level of stability reduces adjustment time and further helps ensure consistency from one performance to the next.

While much of the technical focus centres on capture and control, the success of an orchestral system is ultimately judged by its impact on performers and audience. Subtle details that may not be individually perceived still contribute to the overall experience, making accurate reproduction essential.

Balachanderan emphasises that while he’s worked with many microphones over the years, very few had delivered such a visceral, satisfying sound onstage that musicians themselves could immediately notice. Following a recent performance, one of the ensemble’s cellists commented: “I’ve never heard my cello sound like this in my ears. What did you do?”

“That’s when I knew we’d hit something special,” he recalls. “In an orchestra, every instrument contributes to the collective emotion of the piece. Even if the audience doesn’t consciously hear a specific instrument, they feel it. And if that sound is missing or muddy, the emotional experience is incomplete.”

This winning formula is now regularly being employed across events, forming part of an ongoing workflow rather than a one-off implementation. With further performances scheduled at Expo City Dubai, the requirement to maintain consistency across environments remains an active consideration.

“We’re incredibly proud to have supplied the Neumann MCM 114s to Agora LLC and Firdaus Studio,” concludes Alice Macaluso, brand manager of Sennheiser at Venuetech. “It’s rewarding to see how this microphone has elevated live performances in such a prestigious space. The positive feedback from both the engineers and musicians affirms our belief in the MCM’s ability to deliver uncompromising clarity and precision.”
