Los Angeles, CA (August 26, 2026)—Chris Dwight, monitor engineer for Puscifer and A Perfect Circle, deployed Sennheiser’s new Spectera wireless system for IEMs alongside the Digital 6000 Series for both bands’ recent runs.
“When you’re transitioning from a two-month Puscifer tour straight into a run with A Perfect Circle, consistency and workflow efficiency become everything,” Dwight says. “We weren’t looking for change for the sake of change—we were looking for flexibility and long-term scalability.”
Traditional wireless instrument and monitor layouts require navigating a fragmented grid of individual narrowband frequencies. Powered by Wireless Multichannel Audio Systems (WMAS) technology, Spectera replaces that crowded architecture with a single wideband RF channel, functioning as a unified, bidirectional ecosystem.
“Everything is unified, almost like a cell phone bouncing back and forth to find the best frequency in real time,” Dwight says. “In the morning, I put up my scan antennas, look at what’s available, and export it into SoundBase. Because Spectera condenses all those channels into a single 6 MHz bandwidth, it’s all done in 10 minutes. It’s crazy impressive just how quick it is!”
That speed and bidirectional control proved to be a lifesaver during a high-stakes moment in a Salt Lake City arena. Right at showtime, local venue or security radios suddenly fired up, clouding the environment and causing digital breakup on a few artist packs.
“Because of Spectera’s bidirectional control, I was able to instantly find a new frequency within the software, deploy it, and it updated all the packs simultaneously within seconds while they were on stage,” Dwight recalls.

On stage, Spectera’s SEK bodypacks handle both the artist’s in-ear monitor mix and their wireless instrument transmitter simultaneously, cutting the band’s hardware footprint in half.
“My monitor rack is a fraction of the size it would normally be,” Dwight says. “People probably assume the band is on stage wedges because there’s no massive rack. I own a small digital console package that I can fly around the world. Just knowing I can throw a 1RU Spectera Base Station in a case, check it on an airplane, and have an entire band’s wireless infrastructure with me is a game-changer.”
