new to phono.. Can I hook one up to my preamp?

It is very easy, but I think that the answer to your question depends on what you want to achieve, what turntable and cartridge you are using, how much of your listening time will be spent on LP replay and how much money you wish to allocate to the purchase. There are many, many good phono preamps on the market, just like line level preamps they come in dizzying array of price ranges, from the $30.00 Radio Shack unit to the $30000.00 Boulder unit with a whole lot in between. Just as in choosing a line level preamp, you will have to do a bit of research. Though if you can answer the questions posed above, I am sure that there are many on this forum that can render appropriate guidance. One thing to factor in is that you will also require one more set of interconnects.

Madison, you will need a phono preamp that will connect between your turntable and the line level input of your preamp. The function of the phono preamp is to amplify the small voltage of the phono cartridge to line level and to provide the equalization to reverse the EQ used when manufacturing the record, to produce flat response. If you need more help, feel free to contact me directly.
