Description
Description
Unprecedented features in audio processors!
JFA presents the J4 processor. Its main innovation is the reading of the input and output audio levels on a graphic display. This feature allows the installer to perform a perfect adjustment of the amplifier gains, simulating the use of an oscilloscope. The display has a screen update at the same time as the audio variation, including the storage of 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 incoming audio with clipping indicator, interactive parameter screens, a 15-band semi-parametric "master" EQ, and an individual parametric EQ in each direction.
In audio performance, JFA added a filter that generates more "aggressive and firm" bass, and a metal housing that protects against electromagnetic interference and noise at the outputs.
