Description

The dbx Di4 is a versatile 4-channel active direct box and stereo line mixer designed to streamline complex stage or studio setups. Built into a compact half-rack unit, the Di4 converts unbalanced signals to balanced XLR outputs, making it ideal for interfacing keyboards, samplers, and other line-level instruments with professional audio systems. It's perfect for musicians and engineers who need a simple, reliable way to manage multiple input sources while maintaining clean, balanced output to front-of-house or recording consoles.

In addition to its DI functionality, the Di4 also acts as a 4-channel stereo line mixer, allowing users to control volume and panning for each input, mix them down to stereo via RCA outputs, and even monitor the mix through the built-in headphone output. Each channel features individual 20dB pad and ground lift switches, offering flexible signal handling and noise control. Whether you're on stage or in the studio, the Di4 offers an efficient and intuitive way to manage multiple audio sources with professional-grade results.
