Inside Spectera: How Sennheiser is Redefining Wireless Performance | IBC 2025

At IBC 2025, AVNation’s Tim Albright talks with Sennheiser’s Jonas Naesby to explore Spectera, the Sennheiser’s wireless system powered by WMAS (Wireless Multi-Channel Audio System).

For decades, professional wireless has relied on narrowband RF channels, one frequency, one device, all the time. Spectera changes that model completely. By moving to wideband RF channels, multiple devices can now share spectrum more efficiently, unlocking resilience against interference, higher throughput, and dramatically simplified setups.

“Instead of dividing spectrum by frequency, we’re dividing it by time,” Jonas explained. “This approach gives us diversity, robustness, and the ability to scale up like never before.”

What does that mean for professionals? In an 8 MHz block, operators can run up to 128 devices and 64 audio channels, all on a single rack unit, a single frequency, and even with a single antenna. Plus, two-way communication opens new possibilities for monitoring, remote control, and proactive problem-solving before issues reach the stage.

Beyond reliability, Spectera brings data visibility and easier workflows. From IM pack volume levels to antenna coverage managed over Ethernet, operators gain unprecedented insight and control, all while simplifying deployment.

And Sennheiser isn’t done yet. Alongside Spectera’s bodypacks, the company unveiled its first handheld transmitter at IBC 2025, with software updates like Command Mode and Engineer Mode on the horizon.
