Robert,
Converting analog LPs and singles to digital files is not for those who might be considered technically timid. By that, I mean there is a learning curve involved. There are different ways to go about it. It's not something that can be boiled down into a few simple steps.
The process for any one individual will depend on what equipment he already has and how well he knows how to connect it up and use it, or whether there is something he needs to purchase. It will depend on what level of quality he will be happy with and whether he has equipment that will provide that. It's also helpful to know what a phono preamp is and whether he already has one in the chain of electronics he will be using. Will he be happy with the clicks, pops and surface noise that usually comes with vinyl playback, or will he want to be able to remove that, and does he know how.
I could go on. But hopefully you begin to understand the difficulty in putting all this down into a detailed process. The value of such a process would depend on the knowledge level of each reader. It would be either too simplistic for some, or too technically difficult for others. Each person must climb the learning curve that works for him.
Personally, I would never be happy with the results that that B2 can provide. But I suspect that there are those who would be okay with it. For them, the instructions given at the above link (provided by John) should be clear. If you need further help, post your specific questions in the forum, and I'm sure several people will be glad to try and help.
