Description

Of the many active live boxes that flood the market, only one reference invariably stands out: the irreplaceable and mythical J48. And it's not without reasons!

Can your configuration do without it?
Without knowing it, you already know the J48. Impossible not to see it on the videos of the biggest concerts, in the hands of the technicians of the greatest artists or in any renowned studio. This true monument of audio has consolidated its leading position in the direct box market thanks to its advanced electronic and mechanical qualities, a true brand of Radial.
A legendary endurance and for good reason.
Active direct box, the J48 was developed to convert the high impedance signals of a guitar or a passive bass into a balanced signal suitable for mixing consoles. Any live box of the market is capable of that, will you say to me? Certainly, but the J48 has a secret boot that permanently puts its competitors in the closet: thanks to an optimized internal circuit that takes advantage of phantom power, the J48 is able to handle signals with an amplitude greater than 9 volts and can thus restore the signal of an active keyboard, bass or guitar without any harmonic distortion and with an exceptionally linear response from 20 Hz to 40 kHz. Simply put, the J48 is 100% compliant to the sound of your instrument, where other live boxes provide unwanted saturation and color.
A makeover for your sound.
The purity of the sound delivered by the J48 is not the only innovation that Radial has incorporated into this little wonder. In addition to a conventional instrument input, it has a thru-put output that can be transformed into an input thanks to the built-in Merge function, which allows summing the signals of the two inputs via the XLR output.. Specially designed to provide a solution to problems encountered in the studio and on stage, the J48 provides a phase inverter that neutralizes the problems of feedback on stage, a mass switch able to block the loops and parasites, and a high-pass filter at 80 Hz that reduces unwanted bass-related resonance. A real Swiss army knife!
The robustness of a tank.
Deployed on every stage and in every studio in the world, the J48 has been designed to withstand the rigors of the most infernal tours. Its original design protects from shocks switches and connectors, while its chassis has been developed to eliminate stresses on internal components. The anti-slip mat provides effective mechanical and electrical insulation, and perfect stability on stage and in the studio. Yes, Radial thought of everything!
Robust, of unparalleled quality and thought to solve the majority of the problems encountered in the studio and on stage, the J48 is just the direct box of all superlatives. If you are looking for a direct box that respects your instrument all along the line and that will never fail you, go no further, you found it.

The Radial DI J48 is simply the world's best active DI feedable via phantom. It has been optimized to support high amplitude signals without saturating using only the current 5mA typically available on a phantom power supply. The J48 has a digital switching power supply that can power the circuits in 9 volts!

Most active guitars and basses will provide 7 Volts of amplitude at maximum volume. Since most DIs are able to collect around 3 volts, they saturate.

As the J48 has more headroom, it does not have this problem of saturation. This additional headroom also reduces harmonic, phase and intermodulation distortion.
The J48 addressing all the typical problems that other DI market encounter, the result is immediate: it sounds!

Outstanding features:
+ Headroom (Internal Power Supply 9 Volts)
+ Works without battery (via phantom power supply)
+ High impedance input
+ Switch merge allows summing a stereo signal in mono
+ High pass filter, PAD (-15dB) and polarity switch
