A selection of advanced signal processors designed to improve the quality of your audio experience.

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.

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
