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.
JL Audio's TüN software lets you adjust 10 bands of equalization for each channel and see the results.

More details on the JL Audio FiX™ 82
Overview: The JL Audio Fix82 is a digital signal processor designed to give world-class sound from a factory audio system without replacing the OEM radio. Its 24-bit DSP processor can combine 2-, 3-, and 4-way factory outputs, while automatically level matching into a flat, full-range stereo signal to be passed on to an aftermarket amplifier. The Fix82 will automatically correct factory time delayed outputs before summing the signals and equalizing them with dual, 30 band, 1/3 octave equalizers. Its differential-balanced inputs accept virtually any OEM analog audio signal, from low-voltage line-level to high-power, speaker-level outputs (up to 30V RMS).
Calibration: Basic calibration of the Fix82 is done using the Calibration button on the top panel of the processor. If the button is pressed for 5 seconds, the unit will start the calibration process which takes approximately 30 seconds. The button also serves as an EQ Bypass if pressed for 1 second. By connecting the processor to a PC (via USB) and running the included TuN 2.0 software, you can also access a complete suite of diagnostic panels that will show the frequency response of the input signals, as well as the corrected outputs. This also allows you to adjust the input polarity, muting, and filtering as well as initiating a new calibration. The output can be user-adjusted with a pair of 10-band graphic equalizers.
Turn-On Mode: The Fix82 offers three ways of activation via the top panel Turn-On Mode switch: Signal, DC Offset, and Remote.
- Remote: When the Switched +12 VDC terminal gets 12 volts, the processor powers on.
- DC Offset: Automatically turns on/off by detecting a small DC signal on the OEM speaker outputs.
- Signal: Automatically turns on/off by detecting full-range audio signals on the OEM speaker outputs.
- Input: Factory audio signals are run into the Fix82 through four 4-pin Euroblock connectors for a total of 8 available input channels. Each terminal can accept up to 16 AWG wire. Along with the audio inputs, the processor includes a USB (Type-B, 2.0) port to connect to a PC for running the TuN software.
- Outputs: The processor has two main audio outputs, analog and
- Analog: These consist of a set of stereo RCA jacks outputting a 4 volt (RMS) signal.
- Optical Digital (S/PDIF): The digital port will output a PCM signal at 24 bit/48 kHz resolution. This was intended for use with JL's TwK System Tuning DSP (sold separately) or other processors and amplifiers that have an optical digital input.
- Power/Ground Connector: A 5-pin Euroblock connector provides the inputs for +12 VDC Battery, +12 VDC Switched (remote input if Turn-on Mode switch is set to Remote), Ground, Remote Out (provides a +12 V remote signal to trigger aftermarket amplifiers), and a Valet In. This is provided to attenuate the overall output level by 15 dB if the Fix82 sees a ground on this terminal. This keeps other people from possibly damaging the speakers by turning the volume up too high while the vehicle is being serviced or valet parked.
- JLID Port: The Fix82 has an RJ-45 port for use with JL Audio's optional DRC-100 Remote Controller (sold separately).
DRC-100 Remote Controller: This under-dash mounted rotary control can be used for Master Volume Control or Handsfree Optimization and includes a status LED.
- Master Volume Control: When used as a Master Volume Control, the OEM headunit's volume gets left at the same level it was at during calibration, and the DRC-100 becomes the main volume control. This maintains a linear frequency response and best signal-to-noise ratio at all volume levels.
- Handsfree Optimization: In this mode, the DRC-100 is used to optimize the clarity of the factory Bluetooth hands-free system. By pressing the rotary knob, this disables the processor's time correction and applies a 100 Hz high-pass filter to the output, making Bluetooth phone calls clearer to understand.
- Status LED: The DRC-100's multi-colored LED will show the Fix82's
- Constant green: Normal operation
- Slow flashing green: Valet mode is active.
- Constant amber: Handsfree mode is activated.
- Flashing or constant red: Input signal is clipping (lower volume control on OEM headunit).
