The Boulder 2108 is a top—class reference dual-body phono preamp designed for perfect analog transmission. It separates the audio circuit and the power supply to maximize signal isolation from interference and crosstalk. The device is equipped with three pairs of balanced inputs for connecting different players or pickups and two pairs of balanced outputs.
