If you are not familiar with the function of a preamp and especially a phono preamp then a simple explanation of they do, and why you need one can be found on the ‘what is a preamp‘ page.
This is the Pyle Pro phono preamp. It’s pretty basic. It comes with a power supply, but there is no ‘power on’ light. It’s worth noting that there is no ‘ground’ connection so if your phono turnatable has a ‘ground’ lead (not all have) you may have to connect it directly to the outer of the phono (RCA) plug or the PC chassis if you get a problem with a background hum or buzz.

Here is an offering from Behringer. The PP400 appears to be slightly more sophisticated than the Pyle. It’s powered by an external power supply (supplied), but has a ‘power on’ indicator light which is welcome. Connections are the standard RCA and 1/4″ jacks.
This will cost you more money but is still not expensive for the spec. It has gold plated jacks and a black anodized metal casing. Once again powered by an external supply (supplied) 12 volt DC which will operate anywhere in the world. It also includes an RCA cable and miniplug adaptor.
There is a ground wire terminal and power indicator which is good – the ground wire being something lacking in the previous two products.
