Get A DI Relied On By Countless Pros With The Radial Engineering J48 Phantom Powered Active Direct Box

The Radial J48 has been designed from the ground up to deliver the most natural tone. As a direct box manufacturer, we do not believe it is our task to alter the sound of your prized '1962 Fender Jazz Bass', but retain and transfer the true character of the instrument to the mixing console without adding distortion or introducing artifact. This design philosophy has gained a tremendous following from many of the world's most demanding musicians.

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.

And like all Radial products, the J48 is both feature-rich for studio and made tough to handle the road. This includes a -15dB input pad to tame extra loud signals, 180° polarity reverse for feedback control on stage and a ground lift to help reduce hum & buzz caused by ground loops. Special features include a merge function that elegantly mixes left-right signals to mono without phase cancellation. To minimize resonant feedback with acoustic instruments, the J48 is also equipped with an 80Hz high-pass filter (low-cut). When engaged, this also increases headroom by eliminating unneeded bass frequencies.

Radial's innovative book-end design protects switches and connectors from abuse while the internal I-beam construction eliminates stress on the PC board. This serves to reduce solder joints from going 'cold' and delivers trouble-free performance for years. A full-bottom no-slip pad provides mechanical and electrical isolation while providing plenty of 'stay-put' for rockin' stages!
