About This Listing

The ART dADB dual active direct box acts as two independent, high quality active interfaces for connecting instrument, line, or speaker level signals to balanced inputs. The high impedance ¼-inch inputs are buffered and converted by extremely low noise active electronics to deliver isolated, balanced, low impedance outputs.


The dADB delivers an extremely flat and wide frequency response even at high input levels, making it a virtually acoustically transparent DI solution.


Input attenuation on each channel allows for a wide range of source signal levels. Independent parallel thru jacks allow for tapping the signal chains. A Ground Lift on each channel allows for totally separate the input and output signal grounds to isolate two systems when required, thus reducing hum and ground-loop noise.



  • Fully Active Design
