A DI unit, DI box, Direct box, Direct input, direct injection or simply DI is an electronic device that connects a high impedance, line level, unbalanced output signal to a low impedance mic level balanced input, usually via XLR connector. Dis are frequently used to connect an electric guitar or electric bass to a mixing console's microphone input. The DI performs level matching, balancing, and either active buffering or passive impedance bridging to minimize noise, distortion, and ground loops. Dis do not perform impedance matching. Pyle has been in business for over 35 years, and their manufacturing experience and expertise is easy to see - and hear. Review: Great box for a great price! - Great direct box for the best price I've seen. Works well... the sound guy at church said it not only gave a stronger signal than my setup had been providing, but it also fixed an annoying hum that he couldn't isolate before (using the church's direct boxes). The only recommendation: with the ground lift button (it's a button, not a switch), maybe either add the word "lift" or switch your on/off indications. Since it's a lift, technically (as printed in the instructions), when it's engaged ("On"), the GROUND is disengaged or off (lifted). Right now, when you look at it, it reads that the GROUND is ON or OFF. For those who work with tech all the time, they probably understand the difference, but others might not. Regardless, once you figure out the right position, it works great.

Is this true? How? No power output.** A: It's a passive unit and it will not power up any equipment like guitar or keys. One end has unbalanced input (TR) and parallel out the other end, has balanced XLR so it can be used in a XLR mic input on a mixer. The main purpose is so in a studio setting a guitar player can go into an amp via (parallel out ) and XLR to the input on PA /mixing board to record effects while recording . This will not solve your issue, Example -in my band we rehearse in my studio garage my bass player doesn't bring his amp-( to heavy ) he plugs his bass in to a DI box with 1/4 inch TR (Tip Ring) and the other end I use a XLR cable from the DI box to Mic input on my mixing board. It increases the impedance --Unbalanced to Balanced.. It also has a ground lift to eliminate ground nose (BUZZ) Look for a book "The Ultimate Live Sound Operators Handbook" by Bill Gibson It explains everything. Hope I was helpful. **Q: Can I use this with an audio interface to reduce clipping on Guitar Rig 5?** A: Yes. It will do this by converting then line input from your instrument into a balanced xlr for your audio interface. That is exactly why I purchased this **Q: I need to transform a xlr balance output to and an unbalance one, can i use this device? looking the photo the xlr can be input or output! thanks** A: Hi, yes you can use this unit. You may check other details of the unit by visiting our website pyleaudio.com. Type the model number on the search box PDC21 for more details. Thank you. **Q: Could I use my balanced 1/4 to XLR cable to replace DI box?** A: i tried to use balanced 1/4 with xlr adapter, and never got a reliable connection. di box worked fine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great box for a great price! *by S***. on December 9, 2025* Great direct box for the best price I've seen.
