Every microphone lies to you. It is a small, polite, mostly harmless lie — but it is there, baked into the physics of how a thin membrane converts sound pressure into electrical signal. Push a miniature capsule hard enough — a soprano hitting full voice, a kick drum at close range, a politician thumping the dispatch box — and the membrane's movement becomes non-linear. The electrical output no longer perfectly mirrors the acoustic input. The result is distortion: subtle coloration, harmonic artifacts, a slight hardening of transients that separates "very good" from "transparent."

DPA Microphones has spent years trying to close that gap. Its original CORE amplifier technology, introduced in 2018, applied electronic linearisation at the capsule itself — measuring the membrane's known non-linear behaviour and correcting it in real time before the signal left the microphone. CORE+ by DPA, unveiled at ISE 2026 in Barcelona, represents the next generation: a refinement that the company claims eliminates these non-linearities entirely, delivering what it calls "distortion-free, transparent sound" across the full dynamic range.

It is a bold claim. It is also, if the engineering holds up under independent scrutiny, a genuinely significant one.

The Ecosystem Approach

What makes the ISE 2026 announcement notable is not simply the capsule technology in isolation, but DPA's decision to build an entire wireless signal chain around it. The N-Series Digital Wireless Microphone System operates across 470–870 MHz — a generous 400 MHz of tuning bandwidth that should prove invaluable in the increasingly congested RF environments of modern venues, convention centres, and outside broadcast locations.

The system employs a fully digital architecture with true diversity reception, high-quality microphone preamps, and AES256 encryption — the last of these a requirement for corporate and government work where signal security is non-negotiable. Remote monitoring and control is handled through DPA's Audio Controller software, which includes a wideband frequency analyser for managing channel allocation.

Connecting CORE+ capsules to the N-Series transmitters is the MicroLock connector, a compact, secure coupling that DPA says preserves signal integrity from membrane to receiver output. "What truly sets this ecosystem apart is how seamlessly N-Series and CORE+ pair to preserve audio clarity throughout the signal chain," says René Moerch, Group Product Director for Wireless at DPA Microphones and Wisycom.

Where It Sits in the Market

The professional wireless microphone market at the premium end is dominated by established players. Lectrosonics, the American manufacturer, has long been the default choice for location sound in film and television, prized for its build quality, RF performance, and reputation for reliability in the field. Wisycom, the Italian specialist — notably now under the same corporate umbrella as DPA — offers sophisticated wideband systems favoured by broadcast engineers across Europe. Sony's DWX series remains a staple in fixed broadcast installations.

DPA's entry with N-Series positions it not as a replacement for these systems but as an alternative that begins the signal chain differently — at the capsule. Where competitors typically receive audio from third-party microphones, DPA controls the entire path from membrane to output. That vertical integration is the strategic play: if CORE+ genuinely delivers on its linearisation promise, the advantage compounds through a matched digital transmission chain.

Pricing details have not yet been made public, but DPA's existing product range and its January 2025 acquisition of a majority stake in Austrian Audio — the Vienna-based manufacturer founded by former AKG engineers — place the ecosystem firmly in the premium professional bracket. This is kit aimed at broadcast, theatre, and high-end corporate AV, not pub function bands.

Broadcast and Live Implications

For BBC Scotland's Glasgow production base, where location drama and factual programming demand fast turnaround and reliable audio in challenging environments, a system offering 400 MHz of tuning range and AES256 encryption could simplify workflow considerably. Digital wireless systems have been steadily displacing analogue in broadcast over the past decade, driven by tighter RF spectrum allocation and the need for encrypted, interference-resistant transmission.

Scottish theatre companies — from the National Theatre of Scotland's touring productions to Edinburgh's festival venues — face similar pressures: dense RF environments, quick changeovers between shows, and the eternal tension between miniature microphone placement and sound quality. An ecosystem that promises studio-grade transparency from a lavalier capsule through a wireless link addresses precisely that tension.

DPA is also introducing rechargeable lithium-ion batteries for handheld and bodypack transmitters, along with a charging station capable of handling two transmitters and two spare batteries simultaneously — practical additions that suggest the company understands the operational realities of production work, not merely the acoustic theory.

The Verdict, For Now

ISE demonstrations are not the same as field deployment. The true test of the N-Series ecosystem will come when sound supervisors put it through the particular hell of a rain-soaked exterior shoot in the West Highlands, or a 26-channel corporate event in a glass-walled convention centre bristling with Wi-Fi access points.

But DPA's engineering pedigree is real, its miniature capsules are already an industry reference, and the decision to build a complete, matched signal chain from capsule to receiver represents a coherent and ambitious strategy. This is not merely another wireless transmitter. It is an argument that the microphone and the transmission system should be conceived as one instrument.

That argument deserves to be heard — clearly, and without distortion.
