Lab Overview


  • vinyl noise reduction system detects and reduces vinyl crackle via algorithmic noise reduction system (NRS)
  • connectĀ between your phono preamp and amplifierĀ / power speakers
  • the unit will automatically activate when signal is detected unless bypassed
  • (2) de-crackling intensity algorithms, can be fine-tuned viaĀ front panel knob
  • instant feedback via front panel LED
  • 24-bit DSP /Ā 96 kHz sampling rate for precise processing
  • line-level operation
  • full aluminum housing
  • available in silver or black

"Connect the output of your phono preamplifier to the Vinyl NRS Box S3. First, the line signal gets digitized with a bit depth of 24-bits and a sampling rate of 96 kHz. If the input is too loud, the overflow LED will show it to you. You can then activate the -6 dB switch and the gain is fine now. Crackling parts can be reduced by up to 8 dB which is a big improvement for the listening experience.Ā You can easily adjust the sensitivity with the potentiometer on the front. If you donā€˜t want to use the De-Crackling function, just turn the potentiometer completely to the left and the algorithm is in bypass." -Ā Pro-Ject
