As the Seattle Seahawks and New England Patriots faced off in the NFL’s biggest sporting event of the season on Sunday 8 February, Sennheiser wireless solutions played a pivotal role in delivering pristine live audio throughout the Super Bowl LX broadcast. Brandi Carlile’s rendition of America the Beautiful during the pre-game show marked the sparkling debut of a prototype Spectera SKM handheld, while the Apple Music Halftime Show brought memorable guest performances on the Sennheiser Digital 6000 wireless system by Lady Gaga and Ricky Martin.
Spectera is the world’s first wideband, bidirectional digital wireless ecosystem, enabling simultaneous audio transmission, system control, and monitoring within a single RF channel. It allows up to 64 channels (32 in/32 out) of simultaneous audio transmission, monitoring, and control within a single rack unit, significantly reducing RF complexity and improving stability.
Carlile’s performance featured a custom gold Spectera SKM handheld prototype and Neumann KK 205 microphone capsule, operating at 1 millisecond (ms) latency with 96kHz audio resolution. The Spectera system’s ultra-low latency and high-definition signal path ensured vocal clarity and immediacy across the stadium and broadcast feed.
The star-studded halftime show, led by Bad Bunny, featured dazzling guest performances by Lady Gaga and Ricky Martin, each using custom-finished Sennheiser Digital 6000 handheld transmitters, white for Gaga and silver for Martin.
Across the event, seven Sennheiser wireless microphones and nine stereo in-ear systems operated using just 6MHz of RF spectrum total, highlighting Spectera and Digital 6000’s spectral efficiency in one of live audio’s most congested RF environments.
Jerry Streeter, monitor engineer for Brandi Carlile said: “The clarity and stability were what stood out right away, there is no audible compression, the top end stays smooth on wedges, and the in-ears sound incredibly open. From an RF perspective, getting all that performance on a single TV channel is a game changer.”
The path to the Spectera handheld transmitter’s Super Bowl LX debut began last year, when lead RF coordinator Cameron Stuckey collaborated with Sennheiser on the ambitious New York theatre production Masquerade, where early Spectera in-ear monitoring systems demonstrated reliable, high-channel-count wireless performance in an exceptionally challenging RF environment. When Stuckey was later named lead RF coordinator for Super Bowl LX, that experience sparked discussions about whether Spectera could meet the unprecedented technical demands of the event.
“My comfort with Spectera came from deploying it on Masquerade, an immersive theatre production spanning six floors and 13 performance spaces in the middle of New York City,” said Stuckey. “That project required high-density, bidirectional wireless in a complex structure environment, utilising every feature of Spectera – device capacity, multi-zone operation, modulation diversity. It was the best demonstration of the system’s stability. Knowing the Sennheiser team was as committed to perfection as I was meant it was ready for any production.”
A key factor in bringing the Spectera handheld to the Big Game was the support of Sean Quackenbush, Brandi Carlile’s longtime front of house engineer, and her monitor engineer, Jerry Streeter, who have relied on Sennheiser and Neumann vocal solutions across Carlile’s live performances for many years.
In the weeks leading up to the Big Game, Stuckey and Quackenbush worked closely with Sennheiser to prepare a custom prototype Spectera handheld transmitter for the broadcast.
To ensure seamless coverage through rehearsals and the live broadcast, the production team deployed three Sennheiser DAD antennas covering the stadium bowl, with an additional DAD antenna supporting backstage and preparation areas.
“Spectera allows us to deploy antenna systems in a fraction of the time that coax-based narrowband systems require to get right,” Stuckey said. “Instead of compensating for lossy links or RF-over-fibre conversion artifacts, we define the coverage area, place the DAD antennas, and plug it in. Spectrum selection is the challenge of large events like Super Bowl. Having such a wide tuning range and access to 1G4 spectrum means that Spectera can be used on any show, regardless of size. You’ll see it on TV again soon.”
