Product description
The Atoll Electronique PH100 is a standalone external MM/MC (Moving Magnet / Moving Coil) phono preamplifier designed and handcrafted in France. Built specifically for vinyl enthusiasts wanting a high-fidelity stage, it delivers clean amplification without dynamic compression.
Key Technical Features
-
Dual-Mono Power Supply: Features two dedicated, low-noise linear transformers (one per channel) with four voltage regulators to improve channel separation and lower the noise floor.
- Discrete Component Architecture: The amplification circuit relies on discrete Class-A biased components and eliminates link/coupling capacitors in the signal path for direct transparency and dynamic integrity.
- Shielded Steel Chassis: Encased in a heavy steel housing paired with a 4 mm brushed aluminum front plate to block electromagnetic and radio-frequency interference.
Adaptability & Configuration Rear-mounted DIP switches allow independent adjustments for the left and right channels to match a wide range of cartridges:
- Cartridge Support: Moving Magnet (MM) and Moving Coil (MC).
- Gain Options: 40 dB for MM, 47 dB for High-Level MC, and 60 dB for Low-Level MC.
- Load Customization: Impedance settings of 47 kΩ or 100 kΩ; capacitance settings of 100 pF or 0 pF.
