JFA Electronics J4RED Audio Processor

This item is brand-new, factory sealed.

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. * Screen update simultaneous with audio variation * Peak storage (hold peaks) * Ease of adjusting the limiter function * Interactive screens * 15-band semiparametric master equalizer * Individual parametric equalizer on each path * Oscilloscope function * Voltmeter on the graphic screen * Customizable text * Adjustment of maximum limit of input audio * Input level excess indication * 15 Vpp output * Input channels: 2 * Output channels: 4 * Frequency response: 20Hz to 20kHz * Semiparametric master equalizer: 15 bands -10 to +10dB * Parametric equalizer by channel: 1 band -12 to +12dB * DSP filter, 24-bit high-pass and low-pass: 20Hz to 20KHz, (off/6/12/18/24/36 and 48dB / octave) * Total harmonic distortion: 0,002% at 1kHz * Signal to noise ratio from 20Hz to 30kHz: >90dB * Phase: 0 and 180 Degrees * Delay: 0 and 287 cm * Maximum input level: 0.62VRMS/ 10K Ohms (with input adjustment at maximum) * Maximum output level: 4,6VRMS / 47 Ohms * Bar graph: 0 to 2.1VRMS with hold peaks-in * Dimensions: 202 mm x 103 mm x 43 mm * Weight: 480 gr 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.
