Overview
JFA introduces the J4 processor. Its main innovation is the reading of input and output audio levels in a graphical display. This feature enables the installer to make a perfect adjustment of amplifier gains, simulating the use of an oscilloscope. The display has simultaneous screen update to audio variation, including storing peaks (peaks hold), which favors the adjustment of the limiting function of the processor itself.
In addition to the graphical display, the J4 comes with an adjustment 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 added a filter that generates a more “aggressive and firm” bass, and a metal cabinet that protects against electromagnetic interference, and noise in the outputs.
