Brand New

Description & Specs

Radial JDI Duplex MK4 Stereo DI Box  
  • Stereo direct box for high output sources
  • Ultra linear response from 10Hz to 40kHz
  • Virtually zero phase & harmonic distortion
  • Eliminates hum and buzz from ground loops

The Radial JDI Duplex is a full-feature, stereo passive direct box designed to enhance connectivity, reduce noise, and simplify the hectic life of the touring professional, broadcast engineer or AV integrator. It is plug-and-play easy to use while delivering the utmost sonic quality.

Like the Radial JDI, the Duplex employs two high-performance Jensen audio transformers with the same pristine audio signal path that has made the JDI the industry standard. It features exceptional signal handling with virtually zero phase shift or harmonic distortion, while remaining linear across the entire audio spectrum. When driven to extremes, the natural transformer saturation and resulting warm Bessel curve makes the Radial Duplex the perfect choice for smoothing out highly dynamic instruments such as digital pianos and electronic drums that can sound harsh when pushed. Transformer isolation provides the additional benefit of eliminating troublesome ground loops that can cause hum and buzz in the audio system or interfere with video displays.

This 'Swiss Army knife' DI is equipped with ¼' connectors for instruments, RCA connectors and a 3.5mm TRS for unbalanced -10dB consumer electronics plus XLR inputs for +4dB professional line sources. Radial's innovative book-end design provides protective zones on the front and rear to keep connectors and switches out of harm's way. The 14 gauge I-beam inner frame adds tremendous rigidity to eliminate outside stresses that could torque the PC board and cause premature solder joint and trace failure. The steel outer shell couples with the transformer's MuMETAL® shield to protect against stray magnetic fields from power transformers or lighting systems that could cause interference. Finally, a full-bottom no-slip pad works double-duty by providing both mechanical and electrical isolation. The Radial Duplex delivers outstanding connectivity, superlative audio and quiet dependable performance..

JDI Duplex… the world's finest passive stereo direct box.

We’re all musicians here at Chicago Music Exchange and we want you to love the gear you get from us. We understand that sometimes you get a piece of gear that doesn’t work out for you. That’s why we offer an easy return policy to take the stress out of purchasing from us.

If you decide you'd like to return an item, please contact your Sales Rep, chat us, or give us a call.

If you placed your order on Amazon or eBay, we advise issuing the return request from your account on the platform of purchase - our Customer Service team will process a refund upon receipt of the item(s).

Most new items may be returned within 30 days of delivery and most vintage & used items may be returned within 3 days of delivery for a full refund, exchange, or store credit. Please pack the product safely for the journey back to us. If the product was shipped for free, the charge will be deducted from refund, unless the reason for the return is outside normal circumstances.

Please contact us as soon as possible if your order was received incorrectly, damaged, or defective. Most times we will give you an RA number (Return Authorization). Why is that number important? This will allow us to speed up the process of the return.

We reserve the right to charge a restocking fee based on the return condition. Some items we just can’t take back for returns, due to a one time function like strings or drums heads and other times it’s not sanitary to do so with microphones or harmonicas. If you aren’t sure if what you bought falls into a category like this, call us (773) 525-7773!

We strive to get your return processed quickly. Most of the time we have it done within two business days. Funds going back to credit cards usually takes two to four business days. CME strives to make sure all customers are happy with their experience. It is our priority to provide great service along with great gear. We always want to be helpful, and open to your feedback. Please let us know your thoughts! If you have any questions, we’re here for you!
