DN305 — Noise Masking Processor

The Klark Teknik DN305 is a noise masking processor — a specialised signal-processing unit from the heritage DN-series engineered for installed-sound applications where ambient acoustic masking is required for speech-privacy, open-plan office, or controlled-listening environments.

Noise masking is a discipline distinct from general equalisation: the unit generates a precisely shaped audio signal designed to be inconspicuous yet effective at obscuring intelligible speech and disruptive ambient noise. The DN305 brought Klark Teknik’s reference-grade signal path and engineering precision to that specialised application, finding its home in commercial and institutional installed-sound systems.

The unit is obsolete; service and documentation remain accessible through Music Tribe Care.
