Car Audio Signal Processors
Interface / Correct / Tune A selection of advanced signal processors designed to improve the quality of your audio experience. Analog Signal Processors LoC 22: 2-Channel, Active Line-Output Converter, designed to interface amplified factory audio signals with aftermarket amplifiers. CL-RLC: Remote Level Control and Line Driver works as a master volume control or as a line-level controller for any stereo pair of signals Digital Signal Processors: FiX™: two models of advanced digital OEM integration processors with auto-summing, plus delay and response correction. Designed to interface your factory radio with aftermarket amplifiers and speakers. TwK™: two models of digital tuning processors give you the power to tune up to eight channels of audio with advanced crossover, delay and equalization tools. Why do you need a FiX™?Great audio begins with a flat, full-range stereo signal from its source. Most factory-installed car audio systems are designed with altered audio outputs to compensate for factory speaker quality and placement. In many cases, the only available audio signals are chopped into different frequency ranges, making the integration of quality amplifiers and speakers even tougher. What does FiX™ do?In a nutshell, FiX™ OEM Integration DSPs automatically level match, time-correct, reconstruct and re-equalize factory audio signals, giving you clean, flat, full-range audio signals to build your new audio system around. What about TwK™?Once you have a clean, flat source signal, the TwK™ System Tuning DSPs help take your sound to the next level. Equipped with a powerful, 24-bit digital signal processor, TwK™ processors include flexible input/output options, 80 total bands of equalization, channel delays and powerful mixing tools that allow you to precisely adjust and fine-tune your new audio system. Using the TüN™ Software Interface, connected via PC, tuning adjustments are easily made, for all system types, from basic to complex. Whether you are upgrading a factory audio system or building the system of your dreams, our OEM Integration and System Tuning DSPs are the right tools to achieve world-class sound.
VXi Car Amplifiers
Reference-grade amplifiers with integrated DSP VXi amplifiers combine JL Audio’s advanced amplifier technology with a powerful digital signal processor, all within a compact and beautiful package that is easy to install and offers unprecedented tuning power and flexibility. At the heart of each VXi amplifier is a triple-core AKM® DSP engine with a custom configuration. This powerful DSP not only enables powerful tuning capabilities, but it also helps to improve amplifier audio performance by acting as a master clock for the full-range audio amplifier sections. Further amplifier performance gains have been achieved via minimum loop area output designs, DirectFET® output devices and closely coupled output capacitor banks. The result is a new level of Class D amplifier performance, with outstanding efficiency, reliable power delivery and world-class audio quality. The triple-core DSP engine has ample power to enable a full suite of powerful signal processing functions. These include powerful input switching, routing and mixing that allow a wide range of sources and configurations. Multiple banks of parametric equalization can be assigned to individual channels or groups of channels. Also included for each amplifier output channel and the analog pre-outs: high pass and low pass filters, delay, all-pass filter, polarity and output level trim. Optical, digital pre-outs feature the ability to EQ and level control the digital stream. Instead of using traditional control knobs and switches, VXi amplifiers are easily configured from the driver’s seat, using JL Audio’s free TüN™ software on a compatible computer, tablet or smartphone. Users can define up to six active preset tunings that can be called up at the push of a button using one of the compatible DRC controllers (sold separately).

MVi Marine Amplifiers
Reference-grade marine amplifiers with integrated DSP. MVi amplifiers usher in a totally new level of marine audio performance, with all-new amplifier circuits and amazing on-board tuning capabilities. Each MVi model is packed with a very complete package of digital signal processing (DSP), including EQ, Delay, Crossover Signal Routing, Mixing and lots more. Instead of using traditional control knobs and switches, MVi amplifiers are configured using JL Audio’s free TüN™ software on a compatible computer, tablet or smartphone. While operating the boat, stored DSP presets can be recalled at the push of a button using the optional M-DRC-50 controller, allowing you to instantly adjust the audio system's tuning to suit different activities. MVi amplifiers and their companion MV subwoofer amplifiers are built for years of reliable marine service, featuring a unitary cast alloy chassis with a marine-grade powder coat finish and corrosion-resistant hardware and connectors. Download and test-drive all TüN™ software versions in simulation mode for free (no MVi hardware needed).
