The problem with old records

Everyone has their favourite old vinyl record which is in bad shape from years of use, really noisy and is probably no longer available new either. Many tracks also aren’t available on streaming platforms, so the only way to listen to them is on your original records. For some, the slight noise, pops and clicks are part of the vinyl experience, but at excessive levels, it is not fun anymore and your favourite record might end up sitting on your shelf for the remainder of its long life.

We’re aware of these problems and want to bring those records back on your turntable. The solution is now here, and it is called Vinyl NRS Box S3.

How does it work?

Pro-Ject Vinyl NRS Box S3

Simply connect the Vinyl NRS Box S3 to the outputs of your phono preamp. The real magic takes place digitally. The device digitizes the line signal with a bit depth of 24 bits and a sampling rate of 96 kHz. Here precision double 54 bit accumulators iron out the acoustic damage. Similar sophisticated DSP algorithms come to play in professional recording studios.


Use the potentiometer on the front to adjust the sensitivity. An LED gives you instant feedback on the process. The Vinyl NRS Box S3 can reduce crackling noise by up to 8 dB which improves the listening experience greatly.

To bypass the de-crackling function, just turn the knob completely to the left – and you’re back to pure analog.

Vinyl Noise Reduction System (VNRS)

While the de-crackling function is responsible for irregular pops and snaps, the VNRS circuit dampens constant noise such as surface noise or hums. The VNRS can successfully lower the noise floor by 8dB. This improves the signal to noise ration greatly.

Connection & Setup

Pro-Ject Vinyl NRS Box S3

Connect the Vinyl NRS Box S3 abetween the phono preamp and your preamp or integrated amplifier. Once switched on, the Vinyl NRS Box S3 is immediately activated. Shut off, 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. 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 the level of constant noise is still present you can activate the Vinyl Noise Reduction feature by pressing the VNRS button.

Keeping culture alive

The Vinyl NRS Box S3 gives old records a new lease on life giving them the respect they deserve. Spin on old friend, spin on.
