DN27 — 1/3 Octave Graphic Equaliser

The Klark Teknik DN27 is a single-channel 1/3-octave graphic equaliser from the heritage DN-series, carrying the Proportional-Q response curve that established Klark Teknik as the reference standard for analogue equalisation across touring, broadcast, and fixed-installation sound. The 1/3-octave band count (27 ISO-standard centre frequencies) delivers the surgical resolution engineers need for feedback control and room correction.

The DN27 occupies a historical position in the DN-series catalogue as the single-channel reference EQ that preceded the dual-channel DN360. Its transparent signal path and characteristic filter behaviour remain a benchmark. The unit is obsolete; legacy support and documentation are accessible through Music Tribe Care.
