Klark Teknik DN100 V2 Active DI Box w/ Extended Dynamic Range

The DN100 has earned its reputation as the go-to DI box for discerning engineers and musicians who demand exceptional audio quality. This professional-grade direct injection box combines high headroom with dynamic response and sonic clarity to faithfully capture the character of both electric and acoustic instruments. Its innovative design achieves a significantly higher clipping point than many competing active DI boxes, providing +10 dBu output into a 2 k? load, which means much higher level input signals can be accommodated without requiring an attenuating pad.

Built for the demanding environment of professional touring, the DN100 features robust construction with a thick aluminium extrusion housing protected by a tough silicone rubber sleeve. The unit operates on standard +48V phantom power found on all professional mixing consoles and offers an impressive dynamic range thanks to its very low noise input circuit topology. Only a single -30 dB pad is required when connecting directly to instrument amplifier outputs.

Extensive listening tests using various active and passive bass guitars, electro-acoustic guitars and electronic instruments guided the component selection process to achieve optimal musical sound reproduction. The choice of audio transformer and surrounding component impedances were particularly critical, with the line-driving characteristics carefully optimised for superior frequency and phase responses across short and long cables with varying line and termination impedances. A custom instrumentation-grade input circuit utilises advanced analogue design techniques to create the high input impedance required by passive guitar and bass pickups whilst maintaining low component values to minimise noise.

Practical features include illuminated Pad and Earth Lift switches alongside a +48V phantom power indicator LED, providing clear status visibility even at wide distances and viewing angles. This combination of technical excellence and user-friendly design makes the DN100 an unrivalled choice for professional applications requiring pristine audio capture.
