Behringer DI400P Specification

The Behringer DI400P is a passive direct injection (DI) box designed for professional audio applications, offering a seamless interface between instruments and audio equipment. It features a high-performance transformer that provides impedance and signal matching, ensuring optimal sound quality and fidelity when connecting high-impedance instruments like electric guitars and basses to low-impedance mixing consoles and amplifiers. The unit is equipped with a 1/4-inch input and parallel 1/4-inch link output, allowing the signal to be split and routed to multiple destinations simultaneously. Additionally, it includes a balanced XLR output for direct connection to mixing desks and audio interfaces.

The DI400P is built to withstand rigorous use with a robust metal chassis that shields the internal components from electromagnetic interference and mechanical wear. It is designed to deliver a flat frequency response, preserving the original sound of the connected instrument without coloration. This passive DI box does not require external power or batteries, making it a convenient and reliable solution for stage and studio environments.

The unit also features a ground lift switch, which eliminates hum and ground loop issues by disconnecting the ground connection between the source and destination, ensuring clean and noise-free audio signals. Compact and lightweight, the DI400P is easy to integrate into any setup, providing a practical and cost-effective solution for musicians and audio professionals seeking to maintain audio integrity during live performances and recordings. The Behringer DI400P is an essential tool for achieving professional-grade sound with minimal setup complexity.
