Product description

  • With mounting an accessory car radio or amplifier, unwanted noise often occurs, which are caused by e.g. humming, (humming loop) make noise or whistles noticeable. This is caused by different mass potentials from the car radio and power amplifiers or by incorrect installation of the signal cable to the amplifier throughout the car hi-fi system.
  • This NF suppression filter (or decoupler, noise filter, ground loop insulator) can completely eliminate or significantly reduce most of these noise in the car. The Audioproject A259 has a large and high-quality transformer (separating transformer, power supply), unlike very cheap devices where only a small transformer is often installed. This is cheaper to produce, but this is noticeable in a worse suppression quality.
  • Tip! Power cable and signal cable (RCA cable) do not lay side by side in the car as there is an invisible magnetic field around the power cable, which has a disturbing effect on the signal transmission of the RCA cable (e.g. noise). This then acts like an antenna. Do not wind up too long cables at the end (power and signal), but store separately.
  • International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
