The main innovation of the J4 Redline Processor is the reading of the input and output audio levels on the graphic display, which makes it possible to adjust the amplifier gains. In addition, it simulates the use of an oscilloscope.

To further optimize audio performance of J4 Redline Processor, we added a filter that generates a more aggressive, firm bass, in addition to a metal cabinet that prevents electromagnetic interference and noise at the output.
