To build a high-quality sound system, start with a clean slate
You want to upgrade the sound system in your car with new speakers and amps but without replacing the factory radio. However, your factory system uses unusual EQ curves and preset time alignments that work well with the cheap factory speakers, but will prevent your aftermarket gear from reaching top performance. JL Audio's FiX 82 digital signal processor removes the factory system's equalization, crossover filtering, and time alignment, providing you with a completely flat and focused audio signal that your aftermarket amplifiers and processors can turn into high-fidelity music.
Integrates into almost any system
The FiX 82 was designed to get its input signals from your vehicle's speaker wiring — no outboard level-matching devices are necessary. The FiX 82 automatically re-synchronizes any signals that have been time-delayed, returning precision to the sound. It takes your system's 2-way, 3-way, or 4-way outputs, matches their levels, and combines them into two full-range stereo signals. Then dual 1/3-octave equalizers automatically flatten the frequency response, leaving the system ready for your custom processing and amplification.
Digital features and calibration
It doesn't come much easier than this: pop the calibration CD or loaded thumb drive into your receiver, hit play, push in and hold the FiX 82 calibration button, and all the processing is done in about 30 seconds. The 24-bit 48 KHz digital processor ensures clean, low-noise signal handling and output. In addition to the standard analog RCA outputs, a digital optical output lets you connect to compatible devices with the highest fidelity possible.
Add customized tuning via PC
You can plug your laptop running JL Audio's TüN™ software into your FiX 82 to visualize and correct the system's frequency response. The graphic displays the response curve before and after the FiX 82's corrections.  The 10-band graphic equalizers on the output channels let you fine-tune the sound to fit your car's acoustics and your musical tastes. The TüN software helps when you're setting up your FiX 82, giving you direct control over its factory calibration processing and allowing you to correct the polarity of any of the inputs.
Optional remote for volume control
You'll set up your FiX 82 with the factory radio's volume control at 3/4 full. Once the system is calibrated, you can use the optional DRC-100 Digital Remote Controller (sold separately) to control your system's level while maintaining the processor's EQ restoration. You can still use your radio's volume control without a DRC-100, but the factory volume-dependent equalization will affect the tone at different settings.
In addition to volume control, the DRC-100 features a Handsfree Optimization Mode that disables the FiX 82's time-correction and adds a high-pass filter to the audio to clarify the sound when making hands-free phone calls. A multi-colored LED on the remote report the operational status of the FiX 82, so you'll know what's going on from the driver's seat.
Important Note: Some factory radios and amplifiers will not work without sensing that its speakers are connected to their outputs. If you don't have output from your factory system after installing this FiX processor, you'll need a FiX-LSA-4 load-sensing adaptor (sold separately) to correct the issue.
