Phono Preamp

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.
