Behringer DI100 Ultra-DI Active Direct Injection Box

Connecting unbalanced high-impedance instruments like electric guitars, basses, or keyboards directly to a mixing console often results in signal degradation, hum, and noise. The Behringer DI100 Ultra-DI Active Direct Injection Box solves this by converting your unbalanced signal into a balanced, low-impedance signal that can travel long distances without interference, preserving every nuance of your performance.

Who is it for

Musicians, live sound engineers, and recording studios seeking a reliable, road-ready DI solution. Whether you're on stage, in the studio, or setting up a permanent installation, the DI100 delivers clean, transparent signal transfer with minimal coloration.

Tips

For best results, engage the ground lift if you encounter hum. Use the -20 dB pad when connecting line-level sources or active instruments to prevent clipping. The parallel output lets you send a dry signal to your amp while feeding the PA or recording interface.
