Behringer DI20 Passive DI Box

Dual-channel passive architecture means the Behringer DI20 requires no battery or phantom power to deliver clean signal conversion from unbalanced sources to the balanced XLR inputs at front of house. This direct injection box handles stereo keyboard rigs and backing track playback through two independent channels, each with its own transformer-isolated signal path. The passive design eliminates gain staging and noise floor concerns while the custom-built MIDAS transformers handle the impedance matching and ground loop rejection.

Transformer isolation on both channels cuts hum and RF interference before it reaches the mixing desk. The chassis is compact aluminium that survives years of gig bag transport without losing its ground integrity. Each channel accepts unbalanced input and outputs balanced low-impedance signal via XLR, and the unit offers a summed mono output option when only a single channel is required at the desk. The fully passive topology means zero latency and no power supply hum–related artefacts in the signal chain.
