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 minimise 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.






Easily Connects Instruments

Getting the signal of a musical instrument to the PA system is easier with this direct box. Just connect the electric bass, guitar, keyboard or other processors to the ground lift adapter & enjoy pure & clean audio

Great Sound, Exceptional Value

PDC22 is ultra-compact and housed in a tough, road-ready metal case. This means the PDC22 box will give you great sound gig after gig, session after session. And thanks to its low price, you can afford to outfit the entire band. See for yourself what it can do for your sound.

Direct and Clear Sound

With its parallel ¼ ” In and Out jacks, the PDC22 allows you to plug in your instrument and send the same signal to your onstage amplifier, while the XLR Output sends a balanced signal to your mixer. You can even plug your guitar, bass or keyboard amp’s speaker output into the PDC22, which can handle ratings and still deliver a perfect signal. The superior ground-lift switch eliminates hum associated with ground loops.

Truly Trans-formative

The secret to the PDC22 ruler-flat frequency response is its balanced-line transformer. Praised by audio engineers the world over, the OT-2 provides superior signal isolation from local AC and RF hum, and the ultimate in impedance matching. The resulting output signal is entirely true to the original source – in all its pristine glory.

  1. The 10×12 Studio

    Using as both DI and Reamp box
    I bought this for DI purposes, and it works fine for that. But I just discovered that I can run it in reverse as a Reamp box and that works great too. So I just bought a second one so I can do amp captures.Also discovered I can use Neural Amp Modeler as a preamp on my computer and run a whole lot of different amps through the FX loop on my real amp. Which means I have dozens of amps I can play through a real tube power section and 2×12 cab.Pretty cool for a super inexpensive device. It’s quiet and the ground lift is really handy.

    Great DI’s at a ridiculously low price.
    We had a few DI’s go out on us at our church that needed to be swapped out. Not having the budget available to be able to purchase 4 new one’s at $100 each, these were an enticing alternative. I couldn’t resist the $10 price point and so ordered 4 of these. They’ve done exactly what we’ve need them to do, have allowed us to enhance our sound, and seem durable, especially for the price!

    Works for me
    Our new outdoor karaoke system consist of JBL partybox 1000, Moukey 300ch Mic set, Tenlamp G4 pro mixer, (alternate with Diamondboxx L3 + PAsub15 subwoofer). The whole thing was totally unusable in the last 3 weeks due to excessive RFI /EMI. We have power conditioners, ground loop isolators, none of them work. So I decided to purchase this PYLE-PRO Premium Direct Injection Audio Box. The system is usable again, now better than ever, just like that. No more hum or any other annoying signal noise.I was almost in tears on how pleased we were with this device, think about all the frustrations we had with our rig, and now they just work when everything else we BOUGHT failed.Thanks Pyle (in this case should be pronounced “pal”).

    Great box! Does what it says it does.
    I needed audio isolation and DI functionality for my guitar setup when connected to my mixer. This box does it all and works like a champ. It is also solidly built so it should be around for a long time.
