The Pro-Ject Phono Box SE II is a high-performance solid state phono preamplifier and RIAA equalizer for use with any moving magnet or moving coil phono cartridge (seven selectable impedance settings for MC cartridges). Special low-noise component parts are used throughout the dual-mono circuit design for optimized fidelity and superior channel separation. Gain is rated at 60db (MC). Special attention has been paid to the shielding of the metal chassis to prevent any distortions created from vibration or electromagnetic interference. A subsonic filter provides 24db/octave of attenuation at 18Hz, effectively eliminating low frequency noise and rumble. Gold plated RCA jacks and outboard power supply are included.
