EWI ADB-404 4-Channel Rackmountable Active Direct Box

The ADB box (Active Direct Injection) serves as an optimal connection of a musical instrument with high impedance unbalanced output to a low impedance balanced input of a mixer. By means of the balanced connections to the mixer, interferences can also be avoided in the case of long connecting cables. In case of problems with hum loops, the ground connections between instrument and mixer can be separated by means of the ground lift switch. Then the devices are D.C. separated. High signal levels can be reduced by means of the reductor and can be adapted to the mixer input. Thereby, the ADB box can also be connected directly to the speaker output of an instrument amplifier. Consequently, the influence of the sound at the mixer input will be maintained by the amplifiers (e.g. guitar or tube amplifier).
