Pro-Ject Phono Box SE II

The Phono Box SE II is a premium upgrade from it’s younger sibling, the old Phono Box II. The unit is a better phono preamp, both on technical and acoustic grounds. It is equipped with a higher grade power supply and offers a wide range of cartridge adaptation possibilities. It also has switchable subsonic filter to tighten the bass performance in certain environments. This unit offers a highly musical performance for MM and MC cartridges.

Key Features:

  • Selectable impedance for MC cartridges
  • Selectable load resistance for MM cartridges
  • Selectable subsonic filter
  • Metal case shields the electronics from vibrational and electromagnetic interference
  • Special low-noise ICs used
  • Optimal channel separation through dual-mono circuitry
  • Gold plated RCA connection sockets
  • Outboard power supply included
  • DC operation with battery possible
  • Amplification and RIAA equalisation for MM and MC cartridges
