Description
Behringer DI400P Passive Direct Injection Box
Behringer DI400P is a passive direct injection box designed for signal conversion and impedance matching in stage and studio audio systems. It enables instruments and line level sources to connect directly to mixing consoles and amplification systems, supporting live sound and recording workflows. This makes it ideal for stage setups, studio environments, and installed audio systems where reliable signal routing and noise reduction are critical.
The unit operates using a passive transformer circuit that converts unbalanced instrument signals into balanced outputs for professional audio systems. Integrated ground lift switching and signal routing allow the device to reduce ground loop noise and distribute signals between amplifiers and mixing consoles.
This architecture allows musicians and audio engineers to route instrument signals to mixers while maintaining clean signal transmission over long cable runs. It supports reliable signal conversion and system integration in both live and studio environments.
Key Features
- Passive DI Operation: Passive direct injection box for stage and studio audio applications.
- Signal Matching: Provides impedance and signal matching for connecting instruments to mixers and amplifiers.
- Transformer Design: Utilizes the Behringer OT-2 transformer for ultra-flat frequency response.
- High Power Input Support: Allows direct connection to speaker outputs up to 3000 Watts.
- Ground Lift Control: Ground lift switch helps eliminate ground loop noise.
- Signal Routing: Thru/Out jack allows routing of unbalanced signal to an amplifier while sending balanced signal to a mixer.
- Professional Connectors: 1/4 in TRS and gold plated XLR connectors.
- Durable Construction: Rugged metal housing designed for road use.
- Engineering Origin: Designed and engineered in Germany.
