DBX DI4 Active 4 Channel Direct Box with Line Mixer - DBXDI4

Product Overview

The DBX DI4 is a 4-channel active direct box and stereo line mixer in a half-rack unit, built for keyboard players, multi-instrument rigs, and live sound engineers who need to convert multiple unbalanced instrument or line-level signals to balanced XLR outputs for front-of-house consoles, PA systems, and recording desks. Each channel operates independently with its own 20dB pad and ground lift switch, and the integrated stereo line mixer allows performers to set their own monitor mix.

Product Description

The DBX DI4 solves a common live sound problem: a keyboard player or multi-instrument setup requires four independent direct injection channels plus stage monitoring, all from a single half-rack unit. Each of the four channels accepts a 1/4" TS unbalanced input, applies the appropriate level and ground configuration, and delivers a balanced XLR output to the stage box for the front-of-house engineer. Simultaneously, each channel feeds the internal stereo line mixer, where independent volume and pan controls allow the performer to create a custom stage mix. The master volume control sets the overall level of the stereo line mix output, which appears on rear-panel RCA connectors for connection to stage monitors or in-ear monitor systems. The headphone output on the front panel enables direct monitoring without additional equipment. Available at Creation Networks for touring and installed live sound applications.
