Pro-Ject: Vinyl NRS Box S3 (Noise Reduction System) – (Open Box Special) Pro-Ject

📌LAB POINTS

• vinyl noise reduction system detects and reduces vinyl crackle via algorithmic noise reduction system (NRS)
• connect between your phono preamp and amplifier / power speakers
• the unit will automatically activate when signal is detected unless bypassed
• (2) de-crackling intensity algorithms, can be fine-tuned via front panel knob
• instant feedback via front panel LED
• 24-bit DSP / 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. You can easily adjust the sensitivity with the potentiometer on the front. 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.” – Pro-Ject
