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.

• 4 mm brushed aluminium front.
• 2 very low noise linear transformers 3,2 VA each.
• 4 regulated power supplies.
• Total capacitance: 11,280 µF.
• Input impedance: 47 k or 100 k (*).
• Input capacitance: 100 pF or nothing (*).
• MM gain: 40 dB (*).
• High-level MC gain: 47 dB (*).

• Low level MC gain: 60 dB (*).
• Signal/Noise Ratio at 1 kHz: 80 dB.
• Crosstalk at 1 kHz: < -85 dB.
• Frequency response (20 Hz -20 kHz): <0.1 dB.
• THD: 0.05%.
