JL Audio FiX-86

The state-of-the-art FiX digital signal processor (DSP) is engineered to deliver world-class sound from factory audio systems, without replacing the OEM source unit. FiX 82 and FiX 86 automatically correct time-delayed factory outputs prior to signal summing and EQ correction. With a powerful 24-bit DSP processor and quad 1/3 octave equalizers on board, complex factory signals are combined and level matched automatically into flat, full-range stereo signals. Unlike typical OEM interface products, the FiX DSP automatically corrects time-delayed factory outputs prior to signal summing and EQ correction. Calibration takes just a single button press and about 30 seconds to complete, with no special equipment needed.

Using the TüN software via USB, you can access a complete suite of diagnostic panels that show the frequency response of input signals as well as the corrected outputs. Adjustments can be made to input polarity, muting and filtering, and new calibrations can be initiated from the PC as well. The 8 channel inputs accept virtually any OEM analog audio signal — from low-voltage, line-level to high-power, amplified speaker-level outputs (up to 30-volt RMS). The FiX processor is designed to perform as a turn-on and turn-off controller for the aftermarket components in your system. There are three selectable options to control the method of turn-on: +12-volt remote, signal sensing or DC offset.
