The ADI-20P is a passive two-channel D.I. box. This passive direct box features two audio transformers designed to handle extreme signal levels without distortion of any kind. It converts high impedance audio from instruments or audio line outputs to a low impedance balanced output to be fed directly into a mixing console or amplifier input.
Low impedance (Lo-Z) is capable of longer cable runs via XLR connection with lower signal degradation tan high impedance. No power required.
