Behringer DI4000 V2 Professional 4-Channel Active DI Box

The ULTRA-DI PRO DI4000 gives you 4 first-class DI channels in a single rack space. Each channel is equipped with two Inputs (XLR and 1/4" TRS), a balanced XLR Output - and a 1/4" Link output to connect to your amp or monitor console. Plus, the DI4000 is designed to accommodate virtually any input signal, up to 40 dB of switchable input attenuation and up to 20 dB of gain, while our highly acclaimed OT-1 output transformers ensure pristine and powerful output.

Direct Injection (DI) boxes make it possible to connect guitars, basses and keyboards (as well as other line-level devices) to audio mixers and recorders. The DI4000 takes the DI box to the next level with a special 8 kHz High-Cut filter per channel for guitar applications, along with a Phase Reverse switch for optimal signal alignment. Additionally, our DI4000 active DI features "buffered" inputs that respect your source signal much better than passive DI boxes can outputting optimally-balanced, extremely low-impedance (600 Ω) signals that are far less susceptible to noise and RF Interference (RFI).
