As the Seattle Seahawks and the New England Patriots faced off in the NFL’s biggest sporting event of the season, Sennheiser wireless solutions played a key role in delivering pristine live audio throughout the Super Bowl LX broadcast.
Brandi Carlile’s powerful rendition of America the Beautiful during the pre-game show marked the brilliant debut of a prototype Spectera SKM handheld transmitter, while the Apple Music Halftime Show featured memorable guest performances on the proven 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 supports up to 64 channels (32 in/32 out) of simultaneous audio transmission, monitoring and control in a single rack unit, reducing RF complexity and improving stability.
Carlile’s performance featured a custom gold Spectera SKM handheld transmitter prototype and a Neumann KK 205 microphone capsule, operating at an unprecedented 1 millisecond (ms) latency with 96-kilohertz (kHz) audio resolution. The Spectera system’s ultra-low latency and high-definition signal path ensured exceptional vocal clarity and immediacy across both the stadium and the broadcast feed.
The 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. Their wireless microphones delivered the consistency, transparency and reliability trusted by top-tier artists on the world’s biggest stages.
Across the event, seven Sennheiser wireless microphones and nine stereo in-ear systems operated using just 6 MHz of RF spectrum total, highlighting the exceptional spectral efficiency of Spectera and Digital 6000 in one of live audio’s most congested RF environments.
The clarity and stability stood out from the very first moment: there was no audible compression, the top end stayed smooth on the wedges, and the in-ears sounded open. From an RF perspective, achieving all that performance within a single TV channel is a game changer, shared Jerry Streeter, Brandi Carlile’s monitor engineer.
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 event’s unprecedented technical demands.
“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 Cameron Stuckey, lead RF coordinator for Super Bowl LX. “That project required high-density, bidirectional wireless in a complex structural 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 FOH 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 preparation for the pre-game show, Quackenbush evaluated the Spectera handheld transmitter prototype alongside his preferred Neumann KK 205 capsule and recognised the system’s sonic advantages.
As a front-of-house engineer, the most valuable thing for me is when a vocal mic sounds right without having to fight it. With Spectera, the first thing I noticed was how musical it sounded. The proximity effect felt natural, not exaggerated, and for the first time with a wireless handheld you were really hearing the Neumann capsule itself. It had that German studio quality you expect in a controlled environment, but we were hearing it live, wirelessly, in a stadium. Once you experience that immediacy and clarity, it’s hard to imagine going back, said Quackenbush.
Quackenbush continued: “When we heard it come up in the stadium, it was one of those moments where you just know. The vocal felt stable at high volume, and I barely had to touch EQ. It sounded fantastic in that space. There’s nothing quite like it, and I’m fortunate that I get to push the fader up on it”.
In the weeks leading up to the Big Game, Stuckey and Quackenbush worked with Sennheiser to prepare a custom prototype Spectera handheld transmitter for the broadcast.
To ensure stable coverage through rehearsals and the live broadcast, the production team installed three Sennheiser DAD antennas to cover the stadium bowl, and added a fourth DAD antenna to serve backstage and dressing-room areas.
Spectera allows us to deploy antenna systems in far less time than coax-based narrowband systems, which require very precise tuning. Instead of having to compensate for cabling losses or potential artefacts caused by RF-over-fibre conversion, we simply define the coverage area, place the DAD antennas and connect the system. Spectrum selection is the major challenge at events like the Super Bowl. Having such a wide tuning range and access to 1G4 spectrum means Spectera can be used on any production, regardless of size. You’ll see it on TV again very soon, said Stuckey.
The broadcast debut of the Spectera handheld transmitter during Super Bowl LX highlighted Sennheiser’s next-generation wireless innovation, delivering pristine audio, ultra-low latency and exceptional efficiency on one of the most-watched live broadcasts of the year.
