Behringer DI22P Passive Stereo DI Box

Passive Stereo DI Conversion with Transformer Isolation and No Power Required

The Behringer DI22P is a two-channel passive DI box designed to connect stereo keyboards, backing tracks and other line-level or multimedia sources to professional audio systems. Custom-built Midas transformers provide electrical isolation between the source and destination, helping prevent ground-loop hum while maintaining clean signal transfer.

Its passive design requires no battery or external power supply, making it especially practical for live rigs where you want one less power connection to manage. A high-headroom circuit is designed to accommodate stronger source levels cleanly, while the two-channel layout handles stereo equipment without requiring a pair of separate DI boxes.

Multiple stereo input formats include 6.35 mm (1/4"), 3.5 mm (1/8") TRS and RCA connections, giving the DI22P flexibility with instruments, playback devices and multimedia equipment. A rugged chassis is built for regular stage use.

At Riffs & Licks Music, we think this passive DI box is ideal for performers and audio technicians who need a straightforward stereo connection with transformer isolation, flexible inputs and no reliance on external power.
