The PH100 phono preamp is an external module that has a specific power supply consisting of 2 high-end transformers (one per channel) with very low noise as well as 4 voltage regulators. The assembly is shielded by a metal box in order to preserve any interference on the audio stages. Entirely with discrete components, it does not include any link capacitors. The configurations (MM/MC, input impedance) are directly accessible from the rear of the chassis.
4 mm brushed aluminium front.
2 very low noise linear transformers 3.6 VA each.
4 regulated power supplies.
Total of capacitors: 11 280µF.
Input impedance 47 k or 100 k (*).
Input capacitance: 100 pF or nothing (*).
High-level MC gain: 47 dB (*).
Low-level MC gain: 60 dB (*).
MM gain: 40 dB (*).
Signal/Noise ratio at 1 kHz 80 dB.
Crosstalk at 1 kHz < -82 dB.
Frequency response (20 Hz -20 kHz) <0.1 dB.
THD 0.05%.
(*) Depending on the position of the switches.
