dbx Is The Pedigree of Professional Audio.
Di4
The 4-channel Di4 is designed to be used as a standard tool for many audio applications. Offering 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.

More Details
Using the dbx Di4 as a DI Box:
Connect the signal you would like to convert from unbalanced to balanced to the Di4 via a 1/4-inch unbalanced jack to one of the channel inputs on the front panel of the unit. Connect an XLR balanced cable to the corresponding channel output on the rear of the Di4 and connect to your chosen destination. If the input signal strength is too high you can depress the 20dB pad. If there is an ground (earth) loop hum you can remove by depressing the earth lift switch.
Using the dbx Di4 as a Line Mixer:
You can mix volume and pan of all input signals to a single stereo pair of RCA connections on the rear of the Di4. This enables use of the unit as a fully functional line mixer. Just connect the RCA stereo master 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.

dB12
At dbx, when we do something, we do it right. So when we decided to create our new direct injection boxes, we didn’t settle for the same old tired approach to direct box design. With our dbx name on the line, how could we? One look at our new dB10 Passive and dB12 Active direct boxes will tell you that these are clearly different. With their bullet-proof construction, and extraordinary audio performance to rival their looks, finally there’s a direct box worthy of the dbx name.
Utilizing custom dbx mu-metal-shielded audio transformers, high-quality Neutrik® connectors, and low-noise circuitry preserves the sonic integrity and true characteristics of the signal source. Both boxes include a pad switch that accomodates instrument, line and even speaker level signals. Take even more control of your sound by utilizing the polarity invert switch to set the phase relationship between the direct and mic'd sound.
As a professional, you don’t have time for interference, so we’ve included a ground lift switch to solve potential hum and buzz problems due to ground loops. And between the combined shielding of the cast metal chassis and the custom-wound transformer, you can be doubly assured of a clean signal free from interference. All of this sits atop a solid, stable footprint, that will keep the box from being dragged around the stage, and the unique contoured underside allows secure stacking of multiple units.
