ART dADB

Compact dual active direct box that acts as two independent, high quality active interfaces for connecting instrument, line, or speaker level signals to balanced inputs and delivers an extremely flat and wide frequency response even at high input levels. The high impedance 6.3mm inputs are buffered and converted by extremely low noise active electronics to deliver isolated, balanced, low impedance outputs. 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. Switchable low pass Bessel filters eliminate high frequency interference. Operating outside of the audio range these complex and effective filter circuits are primarily intended to eliminate radio frequency interference before it gets into the main system. They also effectively reduce digital computer noise making it the ideal DI solution for laptops, computer workstations and peripherals when used in stereo PA applications. The unit’s active circuitry is powered by phantom power or by an internal 9V battery when external power is not available. Low current draw (less than 7.5 mA) should provide more than 100 hours of operation with a new battery (alkaline recommended). The compact black all steel case and active design ensure unmatched long-term reliability in live sound, permanent/fixed installations, DJ applications, or virtually any PA application. Dimensions: 51 x 127 x 146 mm. Weight: 1.22 kg.
