What is ANC and why do you need to disable it?

What is ANC and why do you need to disable it?

Active-noise-cancelation(ANC) technology takes advantage of the vehicle's audio system to diminish unwanted noise generated by the engine. To reduce that noise, engineers use active acoustic control or ANC to generate noise-cancellation signals, which are played on speakers in the cars cabin. If this signal is processed by the aftermarket amp you will hear rumbling when engine is revving up or your subwoofers are picked up by the ANC microphones creating a back feed loop. In this situation the ANC must be bypassed.

LLJ ANC bypass harness

  When it comes to adding aftermarket equipment in todays modern rides you will come across ANC or Active Noise Cancelation. This is the process of introducing antiphase to the interior of the cab in an attempt to combat ambient road noise or wind noise. The main problem comes from adding low bass frequencies into your vehicle, that the ANC will pick up on. Our ANC bypass lets you wire in directly to the ANC module in the vehicle and disable the active noise cancelation microphones, thus bypassing the factory ANC. By bypassing the ANC in the vehicle you can go about your installation without having any feedback in your speakers.
 Failing to bypass your factory ANC will lead to a droning or "engine" noise into your audio system. If bypassing the ANC with a bypass is not an option then cutting the wires will also work! In most cases the ANC microphones will be pinned next to data wires so please make sure you have the correct pinout.
 LLJ Customs is the world's biggest designer and manufacturer of ANC bypass harnesses. Like all of our products, we aim to provide a quick and true solution. Some companies, in an attempt to steal our ideas, have decided to upcharge than to provide a product that does work correctly. Our harnesses are true to fitment and in what they bypass. No unwanted surprises. If you have questions please reach out to us.

How Does ANC Work ?

  1. Microphones Placement: ANC systems typically employ multiple microphones strategically positioned throughout the vehicle. These microphones are usually placed in areas where they can effectively capture the ambient noise, such as the headliner, pillars, or door panels.
  2. Noise Analysis: The microphones continuously pick up sound waves from various sources, like engine noise, road noise, wind noise, and other low end sounds. These incoming noise signals are then analyzed by the system to identify their frequency, amplitude, and phase.
  3. Signal Processing: The Electronic Control Unit (ECU) or the central processing unit receives the data from the microphones and performs complex signal processing algorithms. These algorithms analyze the characteristics of the noise and generate a corresponding anti-noise signal.
  4. Anti-Noise Generation: The anti-noise signal is designed to be out of phase with the detected noise. This means that when the anti-noise signal combines with the original noise, they interfere destructively, effectively canceling each other out.
  5. Speaker Output: The anti-noise signal is then transmitted to the vehicle's speakers, which emit the anti-noise waves into the cabin. The speakers are strategically positioned to ensure optimal distribution of the anti-noise signal throughout the interior space.
  6. Cancellation Effect: As the anti-noise waves propagate through the cabin and interact with the original noise, they create zones of destructive interference. In these zones, the amplitude of the combined wave is significantly reduced, resulting in a quieter environment for passengers.
  7. Adaptive Control: Some advanced ANC systems utilize adaptive control algorithms that continuously monitor and adjust the anti-noise signal in real-time. These algorithms can adapt to changes in driving conditions, vehicle speed, and road surface, ensuring effective noise cancellation under various circumstances.
  8. Integration with Vehicle Systems: ANC systems may also integrate with other vehicle systems, such as the audio system or the infotainment system. This integration allows for seamless operation and control of the ANC system, providing drivers with the flexibility to adjust settings according to their preferences.
