About the Pro-Ject Phono Box MKII

Do you have a turntable, but no phono input on your receiver, integrated amp, or shelf system? No problem — just hook up the Pro-Ject Phono Box MKII preamplifer in-line between your record player and any of your receiver's line-level inputs, and you're ready to enjoy your LP collection all over again. Pro-Ject's clean, simple design uses premium quality parts to deliver the warm, relaxed sound that vinyl is famous for. Its compact all-metal body rejects interference to ensure clean sound, and the gold-plated inputs and outputs resist corrosion for the best possible signal transfer.
