Behringer DI22P - Stereo Passive DI-box from the Pro DI Series

The Behringer DI22P is a professional, two-channel stereo DI-box based on passive technology, designed for demanding live sound and studio applications. As part of the prestigious Pro DI series, the device combines signal transparency, robust isolation, and the reliability essential for both the stage and the recording studio. Thanks to its passive design, it requires no power supply or batteries, eliminating the risk of power failure during a performance. It is ideal for connecting stereo keyboards, playing back backing tracks, and routing line-level sources to FOH inputs.

Product Features

Two passive channels — independent handling of stereo signals in a single unit. Transformer isolation effectively eliminates noise, interference, and unwanted ground loops. No power required — pure, passive construction without batteries or power adapters. Rugged chassis withstands touring conditions and daily use. Ground loop isolation ensures a clean, noise-free signal input to the FOH mixer.

Professional Capabilities for Your Creativity

The Behringer DI22P was designed with artists and sound engineers in mind who cannot compromise on signal quality. Thanks to advanced transformer isolation, each of the two channels provides a clean, uncolored signal, which is crucial when working with sensitive line-level sources such as synthesizers, audio controllers, or backing track players. The absence of an active circuit means no added noise, and the passive design guarantees that the signal reaches the mixer exactly as it was generated — without coloration or distortion. This makes the DI22P an invaluable tool in environments where every detail matters. Thanks to its compact and durable construction, it can be easily placed on a rack shelf, studio desk, or carried by hand between sessions and performances. Fuses and protective switches guard against damage resulting from incorrect connections, while precise channel markings facilitate quick identification and connection even in the darkness of the stage. For musicians playing in bands with diverse sonic profiles, the DI22P offers the versatility required by the modern music scene — from electronic projects to traditional rock and jazz formations.
