Dbx Di4

The DBX Di4 is a professional four channel Di box that has been designed to be used as a standard tool for many audio applications. With the use of four channels, the Di4 easily solves the problem of converting unbalanced signals into balanced output suitable for use with mixers, PAs, recording consoles and more. The Di4 also functions as multi-channel stereo line mixer. This feature allows you to connect all your keyboards, samplers and modules into just one rack unit on stage and supply independent XLR balanced outputs to the stage box for a front of house engineer and set your own independent mix for stage monitoring. The Di4 also offers a headphone output.
