JL Audio® OEM Integration DSP with automatic time correction and digital EQ.

JL Audio® OEM Integration DSP

OEM Integration DSP with Automatic Time Correction and Digital EQ. 8-ch. Inputs / 2-ch. Stereo RCA Outputs / 1 Digital Optical Output

The FiX™ 82 is a state-of-the-art digital signal processor engineered to deliver world-class sound from factory audio systems, without replacing the OEM source unit. The FiX™ 82 is the first DSP to automatically correct time delayed factory outputs prior to signal summing and EQ correction.

With a powerful 24-bit DSP processor and dual 1/3 octave equalizers onboard, complex 2-way, 3-way and 4-way factory audio outputs are combined and level-matched automatically into a flat, full-range stereo signal. Differential-balanced inputs accept virtually any OEM analog audio signal, from low-voltage, line-level to high-power, amplified speaker-level outputs (up to 30V RMS).

Calibration is initiated with just a single button press and takes only about 30 seconds to complete, with no special equipment needed!

By connecting a PC running TüN™ Software via USB, you can also 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. By clicking on the “TUNE” tab of the TüN™ interface, you can also access a pair of user-adjustable, 10-band, graphic equalizers to fine tune the output signals.

Output options include dual RCA jacks (4V RMS) or a digital optical (Toslink) output, supporting PCM audio (S/PDIF) at 24 bit/48 kHz resolution.

Activation methods include 12-volt or automatic (Signal/DC-Offset Sensing), plus a dedicated remote turn-on output for activating your aftermarket equipment.

Connect the optional DRC-100 Digital Remote Controller (sold separately) to add Master Volume Control capabilities from the driver’s seat. Clipped input signals and overall condition are also reported via the DRC-100's multi-color status LED.

Achieving great sound from your factory stereo has never been easier, or sounded better.

OEM Integration DSP with Automatic Time Correction and Digital EQ. 8-ch. Inputs / 4-ch. Stereo + 2 Subwoofer RCA Outputs

The FiX™ 86 is a state-of-the-art digital signal processor engineered to deliver outstanding sound from factory source units, while retaining OEM fader control.

Unlike typical OEM interface products, the FiX™ 86 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.

With a powerful 24-bit DSP processor and quad 1/3 octave equalizers onboard, complex factory signals, up to 3-way front and 2-way rear, are combined and level matched automatically into six, full-range stereo signals: Front (fader-controlled), Rear (fader-controlled) and Subwoofer (non-fading, front+rear summed) outputs.

By connecting a PC running TüN™ Software via USB, you can also 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. By clicking on the “TUNE” tab of the TüN™ interface, you can also access four, user-adjustable, 10-band, graphic equalizers to fine tune the output signals.

Differential-balanced inputs accept virtually any OEM analog audio signal, from low-voltage, line-level to high-power, amplified speaker-level outputs (up to 30V RMS).

Activation methods include 12-volt or Auto Turn-On (Signal/DC-Offset Sensing) to trigger a dedicated remote turn-on output for aftermarket equipment.

An optional DRC-100 or DRC-200 Digital Remote Controller (sold separately) adds Master Volume Control and/or Subwoofer Level Control from the driver’s seat.

Achieving great sound from your factory stereo has never been easier, or sounded better... Now with fader retention and subwoofer output!

As factory systems continue to advance, digital sound processors are becoming crucial for factory system integration and ideal sound system building. The PXE-0850X has 6 low and/or high-level inputs that can be mixed to create a full range signal that sends up to 12 independent channels for versatility in OEM and aftermarket system building. Eight of the 12 channels can utilize 25W of powered output to allow even more flexibility.

The PXE-0850X is the next generation of upgraded technology that allows integration into factory systems. New and improved software matches the user interface (UI) of the 16-Channel PXE-X09 Hi-Resolution Digital Sound Processor and provides a cleaner layout that simplifies the mixer and tuning flow.

Objects and materials in the vehicle, like seats, center consoles, leather, and glass, can all contribute to the overall quality of the sound experience. The processor can be tuned with the 31 Band Parametric or Graphic EQ for precise adjustments. Detailed high/low crossovers and expansive time correction can be made to each of the 12 channels. This allows the tuner to overcome acoustical abnormalities in the vehicle and set a proper sound stage for premium sound performance.

Tuning can be done wirelessly via Bluetooth® from a smartphone or through a wired USB connection with a PC. This offers one convenient place to see all inputs/outputs, crossover, time correction, and 31 Bands together for immediate visual recognition. Get real-time tuning results and compare them with the “Before” and “After” effect.

Access to some of the DSP’s features is presented in the included LCD remote controller, which can be flush-mounted on the dash for easy access. The rotary knob can quickly adjust volume, preset storage and recall, subwoofer level, and source selection with results displayed on the LED screen.

Protect your tune and save time by saving a vehicle’s tuning files directly to your smartphone or hard drive. The versatile file system can be shared via text message or email or stored on a thumb drive for storing or sharing.

For vehicles that don’t have a music source, like a head unit or stereo, the PXE-0850X can receive music sent directly from a smartphone with Bluetooth® wireless streaming so you can still enjoy personal playlists without replacing the factory head unit or adding an aftermarket head unit.

Alpine® 16-Channel Hi-Resolution Digital Sound Processor

Built-in Signal Generator (Pink Noise, White Noise, Sinusoid)

For the discerning audio enthusiast who’s looking for a better music experience in their vehicle, the PXE-X09 Hi-Resolution Digital Sound Processor allows you to integrate aftermarket amplifiers and speakers into your vehicle without replacing the factory head unit. The on-board tuning tools give you the power to design a custom listening experience so you can get lost in your music.

The PXE-X09 comes with 16 channels of input and output for various sound system setups. An on-board Real Time Analyzer and a 10-band parametric input equalizer allows you to flatten the factory EQ curve or use as a global EQ. The internal signal generator quickly sends the appropriate tuning sounds to test and tune your system with the option of using pink or white noise or sinusoid.

Built for pros and novices alike, the Configuration Wizard guides you in identifying the components in the factory system as well as the target aftermarket system then appropriately mixes the channels to get a full range signal so you can tune based on your system and your vehicle.

Bring out your sound system’s full potential with the onboard tuning tools. Adjust the active crossover within 1Hz steps to optimize the transition points between speakers in the system. Tune your sound system to perfection with the 31-band parametric or graphic output equalizer. Bring your music to the front and center of your vehicle with up to 20ms of time correction in .01ms steps per channel so every drive feels like a front-row seat at a concert.

Effortlessly tune your system from your smartphone, tablet, or PC (requires a wired USB connection, USB cable included). Get real-time tuning results that you can immediately hear and test with the “Before” and “After” effect to hear the fruits of your labor.

For quick adjustments, use the included LCD remote controller which can be flush-mounted on the dash for easy access. Use the rotary knob to quickly adjust volume, preset storage and recall, bass, and source selection and view results on the LED screen.
