Pro-Ject Vinyl NRS Box S3

Pro-Ject Vinyl NRS Box S3 is a clever solution for vinyl enthusiasts who have treasured records that may not be in perfect condition.

When placed between your phono stage and amplifier, it helps reduce surface noise while preserving the musical character of analogue playback, making older records far more enjoyable to listen to.

FAQ’s

1. What does the Pro-Ject Vinyl NRS Box S3 do?
   The Pro-Ject Vinyl NRS Box S3 reduces surface noise from vinyl records, such as crackle, clicks, and background hiss, helping improve the listening experience when playing older or worn records.
2. Where do I connect the Pro-Ject Vinyl NRS Box S3 in my system?
   The Pro-Ject Vinyl NRS Box S3 is typically connected between your phono preamp and amplifier, allowing it to process the signal before it reaches your speakers.
3. Will the Pro-Ject Vinyl NRS Box S3 remove all record noise?
   While the Vinyl NRS Box S3 significantly reduces surface noise, it cannot completely remove damage caused by severely worn records. However, it can dramatically improve listening comfort for many LPs.
4. Can I bypass the noise reduction if I want pure playback?
   The Pro-Ject Vinyl NRS Box S3 includes a bypass switch, allowing you to instantly disable the processing and listen to the original signal.
5. Is the Pro-Ject Vinyl NRS Box S3 suitable for new records?
   It is primarily designed for older or noisy records, but it can also be used to gently reduce background noise in other vinyl playback situations.

Advanced Vinyl Noise Reduction

The Pro-Ject Vinyl NRS Box S3 reduces unwanted surface noise such as clicks, crackle, and hiss commonly found on older or heavily played records, helping restore a smoother listening experience.

Preserves Musical Detail

Unlike aggressive digital processing, the Vinyl NRS Box S3 is designed to reduce noise while maintaining the natural warmth and musicality that makes vinyl so enjoyable.

Simple Integration into Existing Systems

The unit is designed to sit between your phono preamp and amplifier, making it easy to add to most existing vinyl systems without complicated setup.

Bypass Function for Pure Playback

A convenient bypass switch allows listeners to instantly compare processed and unprocessed signals, ensuring you can enjoy your records exactly as you prefer.

Compact Audiophile Design

Built in Pro-Ject’s compact S3 chassis, the Vinyl NRS Box S3 integrates neatly into modern Hi-Fi systems while maintaining high-quality analogue circuitry.

How does it work?

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. The real magic happens in the digital domain.

De-Crackling

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.

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.
