Cleanse Your Filthy Old Records of Their Clicks and Pops

Everyone has their favourite old vinyl record which has gotten damaged over time, is quite noisy and maybe not even available to buy new anymore. Many obscure recordings are also not uploaded to streaming platforms, so the only way to listen to them is on vinyl, but not everyone takes the greatest of care with their collection. Whilst some gentle clicks and hisses here and there can be charming, outright snaps, crackles, and pops can turn you off ever listening to a record. Enter the Vinyl NRS Box S3.


  • De-Crackling function to reduce clicks
  • Noise reduction for vinyl records
  • Reduces noise of the turntable drive
  • Processing based on DSP with 24 bits
  • 96 kHz sampling rate for precise processing
  • Galvanic pure bypass if switched OFF
  • Ideal transfer characteristics and linearity
  • De-Crackling with adjustable sensitivity
  • Line-level operation
  • Compact design in standard S3-line case
  • Full aluminium housing
  • Available in silver or black

So How Does It Work?

The Vinyl NRS Box S3 digitises a line signal with into a 24bit/96 kHz signal. High frequency signal components are used as a marker for crackles. The dedicated algorithm can now detect these peaks, and neutralise them. You can easily adjust the sensitivity of the noise reduction with the control knob on the front of the unit. Crackling noises can be reduced by up to 8 dB which significantly improves the listening experience.


The signal gets filtered to not interfere with the processing itself. High frequency components are used as a marker for crackles. The dedicated algorithm can now detect these peaks. You can easily
adjust the sensitivity with the potentiometer on the front. The LED gives you instant feedback on the process. Crackling parts can be reduced by up to 8 dB which is a big improvement for the listening experience. If you don‘t want to use the De-Crackling function, just turn the potentiometer completely to the left and the algorithm is in bypass.

Vinyl Noise Reduction System (VNRS)

The signal is first separated into two frequency bands and then fed into two expanders, which increase the signal-to-noise ratio. There are no noise modulations audible using this technique! We are able to reduce the noise by up to 8 dB.

Connection & Setup

The Vinyl NRS Box S3 is connected between the phono preamp and your preamp or integrated amplifier. If you turn it on, the Vinyl NRS Box S3 is active immediately. If you don‘t want it in your signal path, just turn it off and the device is bypassed and the inputs are galvanicaly connected to the outputs. There are two De-Crackling intensity algorithms available: the basic one processes the signal very lightly; the advanced is stronger with more heavy processing. Always try the basic setting first & adjust the intensity with the potentiometer. By pressing the „Intensity“ button you can engage the advanced mode if wanted and/or necessary. The LED shows you if clicks & crackles are reduced. If you‘re happy with the De-Crackling setting, but you can still hear a lot of noise, you can now activate the Vinyl Noise Reduction feature by pressing the VNRS button. There is only one preset for the Vinyl Noise Reduction feature and it cannot be customized in the same way the De-Crackling can be adjusted.
