Pro-Ject Box Design Vinyl NRS Box S3

To use the Vinyl NRS Box S3, it needs to be connected to a turntable system via its Line Level input, so it only works after the phono stage in the signal path. Once connected, it should simply be switched on and the “De-Crackle” function will initiate. The strength of this process can be tuned using the front-mounted dial and can even be increased further by clicking the Intensity button. Separately, the Vinyl Noise Reduction System can be started with a push of the VNRS button, dramatically reducing vinyl surface noise and turntable motor noise.  

Thanks to its sophisticated digital signal processing algorithms, the Vinyl NRS Box S3 first converts the analogue music to a high resolution 24-bit / 96kHz digital format for minimal signal loss, and then separately initiates each process – depending on the current settings and the position of the De-Crackle dial. This allows you to run one or both processes at the same time. For times when the input signal is too high, the -6dB switch allows for the original signal to be attenuated before passing to the digital stage.

We endeavour to despatch same day for orders placed up to 1pm on available stock items (items with stock message "Usually dispatched within 24 hours"). Please remember to check with us first for a physical stock check if next day delivery is important to you. Any items with stock message "Usually dispatched within 72 hours" are items that we do not hold in stock but order in from the importer or manufacturer as soon as a customer order is received. Occasionally these may be delayed beyond 72 hours due to importer/manufacturer stock levels but we will inform you as soon as we can if this is the case.

Smaller items are delivered using Royal Mail 24 or special delivery. Larger items are delivered using a courier service such as DPD or UPS.

International Orders:

Due to the nature of our products and brand restrictions we are only able to send certain items internationally. Smaller items are delivered using Royal Mail Small Packets Airmail with International Tracked and/or Signed depending on value of item and availability of the service. Larger International shipments are sent by insured and tracked services using UPS. If there are any delays due to specific customs regulations, etc, you will be contacted by Hifisound or by the courier with a request for any further information required. Customs duties can apply for shipments to any countries outside of the UK depending on where the product you have bought is made. Customers are responsible for all taxes and duties incurred when the items enter their country.

Collect in Store or Home Install

At the request of the manufacturer some items cannot be supplied by mail order but you can click and buy them and then elect to collect them from our store or arrange a home install (if applicable). Applicable items clearly state that they are Collect in store or home install. Once ordered you will receive a message prompting you to contact us by phone or email to arrange for us to deliver and install or to reserve and collect from our store at your convenience, you will also be advised of the delivery time / stock availability as not all Home install / collect in store items are held in stock.
