Dbx Di4 Box

Description

DBX DI4 BOX

The 4-channel Di4 is designed to be used as a standard tool for many audio applications. By offering four channels, the Di4 easily solves the problem of converting unbalanced signals to a balanced output suitable for use with mixers, amplifiers, recording consoles, and more. The Di4 also functions as a multi-channel stereo line mixer. This feature allows all keyboards, samplers, and modules to be connected into a single rack unit on stage and provide independent balanced XLR 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.

Using the dbx Di4 as a DI Box:

Connect the signal you wish to convert from unbalanced to balanced to the Di4 via an unbalanced 1/4 inch jack to one of the channel inputs on the front panel of the unit. Connect a balanced XLR cable to the corresponding channel output on the rear of the Di4 and connect to your chosen destination. If the input signal power is too high, you can press the 20 dB pad. If there is a ground hum, you can remove it by pressing the ground lift switch.

Using the dbx Di4 as a Line Mixer:

You can mix the volume and pan of all input signals to a single stereo pair of RCA connections on the rear of the Di4. This allows the unit to be used as a fully functional line mixer. Simply connect the master stereo RCA outputs on the rear to your chosen destination and adjust the individual volume and pan controls for each individual channel on the front of the Di4 to suit your needs.
