Pro-ject Audio presents the first affordable component that electronically smooths out the physical wear and tear that your may records endure over the years. Now, you can get more joy out of your compromised records or those you find at flea markets or bargain bins.
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 favorite record might get banned to an existence on your shelf for the remainder of its long life.
There is a solution to this, according to Pro-Ject. Simply connect the Vinyl NRS Box S3 to the outputs of your phono preamp. The real magic takes place digitally. The line signal gets digitized with a bit depth of 24 bits and a sampling rate of 96 kHz. Here double 54 bit precision accumulators iron out the acoustic damage. Similar sophisticated DSP algorithms are used in professional recording studios, the company says.
The device features a potentiometer to adjust the sensitivity and an LED gives instant feedback on the process. According to the press release, crackling noise can be reduced by up to 8dB 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.
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, therefore improves the signal to noise ratio greatly, Pro-Ject states.
The Vinyl NRS Box S3 should be connected between the phono preamp and the preamp or integrated amplifier. Shut off, the device is bypassed and the inputs are galvanically 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.
