Advanced audio DSP technology

Our noise cancelling PCB modules are compact yet powerful units designed to reduce background noise and make speech clearer. Each module utilises sophisticated Digital Signal Processing algorithms to identify and remove background noise while preserving the clarity of the speech. Perfect for new designs and retrofitting into existing radio equipment, these modules can be integrated into the microphone path or receive audio path, depending on your specific requirements.

Superior noise cancellation performance

The noise cancellation capabilities of these PCB modules make them ideal for use in high-noise environments where communication clarity is essential. The DSP noise cancellation technology can reduce background noise by up to 40dB whilst maintaining natural voice quality. The result is crystal-clear audio, even in the most challenging acoustic conditions.

Versatile integration options

These PCB modules are designed with flexibility in mind, offering various integration options to suit different applications:

  • Direct microphone path integration for noise cancellation at the source
  • Receive audio path placement for cleaner output signals
  • Pre-wired options for simpler installation requirements
  • Compact form factors to fit space-constrained designs
  • Compatible with a wide range of audio equipment

These can be installed in:

  • Yaesu FT817, FT-847, FT-857, FT-8o97 & FRG100
  • Kenwood TS-50, TS-430S, TS-440, TS-850
  • Alinco DX-77, DX-SR8T,
  • Icom 706 MKII G, IC-705, IC-725, IC-765 & IC-736/738, IC-7300
  • Realistic DX-394
  • Collins KMW2
  • Drake R7
