JFA features the J4 processor. Its main innovation is the reading of the input and output audio levels in a graphic display. This feature allows the installer to make a perfect gain adjustment of the amplifiers, simulating the use of an oscilloscope.

The display has updated the simultaneous display of the variation of the audio, including storing the peaks (hold peaks), which favors the adjustment of the limiter function of the processor itself.

In addition to the graphical display, the J4 comes with a setting to limit input audio with clipp indicator, interactive adjustment screens, 15-band semi-parametric master equalizer and individual parametric equalizer on each track.

In audio performance, JFA has added a filter that generates a more "aggressive and steady" bass, and a metal enclosure that protects against electromagnetic interference, and noise at the outputs.
