The Klark Teknik DN60 is a real-time 1/3rd octave spectrum analyzer built for professional audio measurement in studios, concert halls, and test laboratories. It displays 30 ISO frequency bands across 15 Hz to 22 kHz with selectable 1 dB or 2 dB resolution, switchable A-weighting, and dual detection modes—average for steady-state levels and quasi-peak for transient capture. Peak hold and three memory locations enable precise sound system alignment and acoustic analysis.
