The DBX Di4 is a versatile 4-channel direct injection (DI) box designed for professional audio applications, including live performance, studio recording, and stage monitoring. Perfect for converting unbalanced instrument and line-level signals into clean, balanced outputs, the Di4 ensures superior sound quality for mixers, PA systems, and recording consoles.
Beyond its DI capabilities, the Di4 doubles as a multi-channel stereo line mixer, allowing musicians to connect keyboards, samplers, and modules in a single 1/2 RU unit. Each channel offers independent volume and pan control for a custom stage mix, while the balanced XLR outputs provide clean signals for front-of-house engineers. A built-in headphone output allows monitoring without affecting the main mix.

-
Connect unbalanced 1/4” inputs to the front panel channel inputs.
-
Output via balanced XLR connections to your mixer or PA system.
-
20dB pad switch reduces input level for high-output sources.
-
Ground lift switch eliminates hum caused by ground loops.
