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. This preamp is compatible with both moving magnet and moving coil cartridges, so you can count on proper matching with virtually any turntable and cartridge combination.
