Pro-Ject Vinyl NRS Box S3

Product Summary

The Pro-Ject Vinyl NRS Box S3 is a specialist vinyl noise reduction unit designed for customers who want to get more enjoyment from older or noisier records without giving up their existing turntable setup. It sits between your phono stage and amplifier, helping reduce clicks, crackle and background noise so damaged or worn records can become much more listenable again.

A big part of the appeal is that it is designed specifically for vinyl rather than as a general audio processor. The Vinyl NRS Box S3 combines adjustable de-crackling with its Vinyl Noise Reduction System, giving you a more useful way to tackle both obvious clicks and broader low-level noise. That makes it especially attractive for customers with older collections, well-loved records or discs that are hard to replace.

It is also straightforward to integrate into a system. Because it works at line level after the phono preamp, it can be added without changing the turntable itself, and when switched off it drops out of the signal path via galvanic bypass. For customers wanting a practical way to bring noisy records back into regular use, the Vinyl NRS Box S3 is a very distinctive and genuinely useful upgrade.
