The build quality and internal magic of Radial DI products is simply undeniable. J48 is a phantom powered DI, with ultra low distortion and massive headroom. It's perfect for acoustic guitar or bass, and has a -15dB input pad should your active pickups squirt it out a bit hot for other DI products. For keyboardists, you can plug your right channel into the 'throughput' and press the handy 'merge' button that "elegantly mixes left-right signals to mono without phase cancellation." Yes, it's the full package.

  • Powered by 48V phantom

Using only 48V phantom power, the Radial J48 is an active direct box that produces an exceptionally linear response that extends from 20Hz up to well above 40kHz. Low distortion of all types is achieved via a unique digital switching power supply that raises the internal operating rail voltage for added headroom and improved signal handling. The results are truly amazing. The J48 delivers an ideal even-order harmonic cascade and a sonic performance that outperforms DIs costing several hundreds more.
