The PH100 phono preamp is an external module with a specific power supply consisting of 2 high-end transformers (one per channel) with very low noise and 4 voltage regulators. The assembly is shielded by a metal box to preserve any interference on the audio stages. It is entirely made of discrete components and does not include any link capacitors. The configurations (MM/MC, input impedance) are directly accessible from the rear of the chassis.
