DPA Microphones N-Series Digital Wireless System users in North America can now take full advantage of the system’s exceptionally wide tuning range with a new firmware update. Recognized for advanced features such as True Radio Diversity and a 400 MHz super-wide tuning bandwidth, the new N-Series firmware provides customers in the U.S. and Canada with Duplex Gap and Guard Band access for a broader usable spectrum.
DPA will unveil this update at NAB 2026. With the new firmware, all N-Series users will gain access to the 2 MHz Guard Band as well as the 6 MHz unlicensed portion of the Duplex Gap. Owing to the highly linear RF design and extremely low intermodulation characteristics of the N-Series, this increased space can accommodate up to 16 additional wireless channels.
That margin is significant for houses of worship, regional theaters, corporate AV environments and other multi-channel applications.
Reliable spectrum is one of the biggest pressures facing customers mixing a broadcast, managing a large event venue or supporting complex productions, said Christopher Spahr, vice president of sales and marketing for DPA Microphones U.S. This update will give engineers more confidence and room to work.
By extending what N-Series can access, we offer higher channel counts with greater predictability and less risk of interference in some of the most challenging RF environments, Spahr said. It is a powerful example of how DPA continues to support its customers with improved performance through innovation and thoughtful engineering. We are especially excited to demonstrate what this means in real-world applications at NAB 2026.
