Review: I use this with my keyboard setup for regular rehearsals and gigs. So far it is meeting all expectations : a good quality, reliable DI unit which is a slightly higher price than others but (in my opinion) is also comparably superior. As others have said, this thing is built like a tank. I've never had any issues with additional noise or connection problems, which I can only assume is a good thing. Great piece of kit. Review: I have to say, this DI box is an absolute powerhouse. It's built like a tank and can withstand just about anything you throw at it. Whether it's being jostled around in a gig bag or dropped on the floor, this DI box just keeps on working. What's even better is that everything about this DI box just works. The sound quality is fantastic and it does exactly what it's supposed to do - take an unbalanced, high-impedance signal and convert it to a balanced, low-impedance signal. I've used it for everything from recording to live gigs, and it's always performed flawlessly. But what really sets this DI box apart is its durability. It's probably the best in the industry, and I've seen firsthand just how tough it can be. It's been dropped, and stepped on, but it still keeps on working like a champ. Overall, if you're in need of a DI box that's incredibly durable and reliable, this is definitely the one to go for. It's built to last, sounds great, and just does what it's supposed to do. Highly recommended! ## Features - Comes from the brand Radial Engineering - Compact construction - Sleek design - Seamless functionality ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000B85FV0 | | Color Name | Green | | Customer Reviews | 4.7 4.7 out of 5 stars (451) | | Date First Available | 6 August 2012 | | Item Weight | 544 g | | Item model number | R8001102 | | Product Dimensions | 16.26 x 10.92 x 7.87 cm; 544.31 g | ## Images ![Engineering ProD2 Passive Channel Direct Box - Image 1](https://m.media-amazon.com/images/I/71FVFWf5SmL.jpg) ## Questions & Answers **Q: I have a gibson ed335 and when i run it into my fender deluxe amp i always hear a hum. is it customary to run this between a guitar and an amp all th** A: Did you mean es335? That Gibson has humbucking pickups so shouldn’t be very hummy. It’s customary to run a bass though a DI that way, but not guitars unless you are using pedals only to create your tone. If you rely on your amp and speaker for your sound it would be better for the sound person to put a microphone in front of your speaker. Try comparing your amp to another at the same location to see if the hum is as loud. Fluorescent and neon lights an motors can radiate hum which can be picked up by a bad cable or a problem inside your amp or guitar. The main purpose of a direct box is to convert a single-ended high impedance signal to balanced line low impedance that can be sent over long distances, cancelling hum that is picked up in the cable going to the mixer. If there’s hum before the DI there will be hum after it. **Q: I got a general question. If I am getting a direct box... does it matter if the cables are balanced or unbalanced?** A: Most DI boxes convert an unbalanced high impedance signal to a low impedance balanced signal. So, you can use unbalanced in and balanced out. A balanced cable has more noise rejection and is better for longer cable runs. The Radial ProD2 takes 2 unbalanced 1/4 inch TS connectors in and converts then to 2 XLR balanced outputs. **Q: Looking to pass a stereo out from MacBook pro, through a volume pedal, to the di, and out stereo to the board. I play live through logic + mainstage.** A: Hello Brandyn,If you are using an audio interface with the MacBook Pro, the ProD2 would be perfect. If you are using the built-in sound card of the MacBook Pro, you will want something like the Radial StageBug SB-5 Sidewinder Laptop DI (as it is outfitted with a stereo 3.5mm connector, so you don't need any adapter). The Pro D2 will work with a laptop's built-in card, but will require (1/4" to 1/8") adapters - which is not recommended (minimal "patch points" is always the best route). Let us know if we can help with anything else. We at Front End Audio are happy to do what we can.Thank you! **Q: I require 5 Passive stereo DI boxes - From 8 bucks to 300 bucks? Is there a reasonable quality and reasonable price you would reccomend for me ie a stereo Yamaha S90 Keyboard? I have one ProD2** A: I would actually recommend the Radial Pro D2. It's the most reliable DI box we sell. If your using it for the Yamaha S90, you really don't want to buy anything cheaper. Thanks. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by H***S on 3 July 2019* I use this with my keyboard setup for regular rehearsals and gigs.

Highly recommended! ### ⭐⭐⭐⭐⭐ Review *by A***R on 17 October 2016* Very good product. No noise added. Sound quality is good. XLR output is just transformer's secondary winding so should not connect to mic in port that gives phantom power. In PC mic out, it gives 3V phantom power for microphone. When connected to XLR, it was like short circuit and voltage was dropping and caused click sounds. Added two nonpolar electrolytic capacitors in the circuit to block voltage and pass signal, now working correctly. ## Frequently Bought Together - Radial ProD2 Passive 2 Channel Direct Box - Radial Pro DI Passive Direct Box - Cable Matters 2-Pack Premium XLR to XLR Cables - 6ft, Male to Female Microphone Cable, Oxygen-Free Copper (OFC) Mic Cord, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/283499945-engineering-prod2-passive-channel-direct-box](https://www.desertcart.in/products/283499945-engineering-prod2-passive-channel-direct-box) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-04-23*
