It is Only the board, which has been assembled and tested.
It is a Hi-Fi turntable phono pre-amplifier that allows you to connect low signal output turntables, magnetic cartridges to an amplifier, or sound mixer that has normal stereo line level inputs (100-300mV).
You can use this good quality RIAA equalised pre amp without signal loss or distortion and avoid to buy expensive sound amplifier or sound mixer.
You can connect it to the sound card of your computer and convert your old records in mp3.
