Review: The Radial USB-Pro Stereo USB laptop DI box works great. I use it to run .wav files from a laptop through my tube compressor into my DAW with zero quality loss. (unlike using the high impedance out of a headphone jack which is a very noticeable loss in dynamic range and overall sound.) The beautiful part of the process is the drivers seem to be included in this device and when I plugged it in to my Windows 7 64bit laptop the device just worked. I am very happy with Radial products and have a handful of their di boxes. I will continue to use their products as they are solid, transparent and reliable. ## Features - Stereo DI for laptops with level control, mono summing and headphone out - High performance 24bit/96k stereo direct box. - Automatically installs without the need of a driver. - Built-in headphone amplifier for monitoring. - Balanced Lo-Z outputs with switchable isolation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E5LY4DO | | Brand Name | Radial | | Customer Reviews | 4.6 4.6 out of 5 stars (97) | | Global Trade Identification Number | 00676101040599 | | Interface | USB | | Item Dimensions L x W | 7.5L x 5.5W centimeters | | Item Weight | 1.74 Pounds | | Manufacturer | Radial | | Material Type | Metal | | Model | R800 1050 | | Mounting Type | Panel Mount | | Number of Channels | 2 | | Number of Pins | 10 | | Part Number | R800 1050 | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 676101040599 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Radial - **Interface type:** USB - **Mounting type:** Panel Mount - **Number of channels:** 2 - **Number of pins:** 10 ## Images ![Radial Engineering USB-Pro Stereo USB Laptop DI - Image 1](https://m.media-amazon.com/images/I/71kMCjTAplL.jpg) ## Questions & Answers **Q: In your opinion, does the radial usb-pro sound much better than the radial jpc? looking for a solution that will accept both laptop and ipad audio.** A: Hello, both radial devices are great. It really comes down to the individual preference. We find the USB Pro is the device of choice for laptops and Ipad. Thank you. **Q: Will this work with an iPad if you use the apple lighting to usb 3 camera adapter powered with a usb charger?** A: I doubt it, as the ipad most likely doent have drivers for the interface…but who knows? **Q: Is this DI bus powered or does it require phantom power or a battery?** A: Bus powered. USB in, XLR out...that’s it! No phantom or external power required. **Q: What kind of latency does this device introduce when receiving output from MainStage 3?** A: Theoretically there may be some latency, but it is so infinitesimal as to be imperceptible. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***E on 30 August 2022* This makes my live setup so much easier and sounds great!! ### ⭐⭐⭐⭐⭐ Review *by C***H on 20 March 2016* The Radial USB-Pro Stereo USB laptop DI box works great.

The Radial USB-Pro works great in some situations, no software needed, easy to use, built tough, but it requires power from the device connected. All Apple mobile products sense when a device is connected and tries to draw power and immediately gives an error message and won't let it connect. You can get around this by buying an adapter that allows you to connect both to the device and a power source, but now you've got a mess of cables and connections. I've also experienced audio drop outs on the right channel. At first I blamed it on the devices connected, I'd unplug the USB cable, reconnect and everything would work great again. 6 months later of still struggling with periodic drop outs, I noticed that if I wiggled the cable close to the Radial USB-Pro, the right audio track would come back. I replaced the cable thinking maybe it was damaged, but the problem continues (I'm also uncertain how a digital signal could possibly drop one side of the audio due to a "bad" cable). For non critical playback, or mono playback it works, but I can't trust this for anything important. This is not like all of my other Radial products which are rock solid decades later. I'm contacting Radial to see if anything can be done to make this more reliable, but in the mean time, I've purchased a Sonnect Soundwire with hopes of a simpler and more reliable solution to my playback demands. UPDATE Radial support reached out with multiple suggestions on how to diagnose the problem. Embarrassingly enough, the problem with dropouts was likely caused by the XLR cable I was using. 1 week after replacing the XLR cables used, I've not had any dropouts. As I've said before, I'm a huge fan of Radial Engineering, the only downside now is the power injection problem when using Apple products. ## Frequently Bought Together - Radial USB-Pro 2-Channel Active Instrument Direct Box - CableCreation USB B to USB C Printer Cable 6.6FT, Type B to Type C Printer Cord for MacBook Pro, Air, MIDI Cable for Yamaha Casio Digital Piano, MIDI Keyboard, DJ Controller, DAC to iPad - 2M, Black - Korg nanoKONTROL2 Slim-Line USB Control Surface, 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.pl/products/332531823-radial-engineering-usb-pro-stereo-usb-laptop-di](https://www.desertcart.pl/products/332531823-radial-engineering-usb-pro-stereo-usb-laptop-di) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-28*
