Description
Atoll PH200 : Phono Preamp
The PH200 phono preamplifier is an external module with a special power supply consisting of two ultra-low noise high-end transformers (one per channel) and four voltage regulators. The entire unit is shielded with a metal box to prevent interference with the audio stage. Constructed entirely from discrete components and contains no intermediate capacitors. Settings (MM/MC, input impedance) can be accessed directly from the back of the case.
- 8 mm brushed aluminium front panel.
- Silver mica technology RIAA filter capacitors.
- 2 very low noise linear transformers 3,5 VA each.
- 4 regulated power supplies.
- Total of capacitors: 54 400 µF.
- Input impedance: 47 kΩ.
- Input capacity: Nothing / 100 pF / 220 pF / 320 pF(*).
- 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: < -86 dB.
- Frequency response (20 Hz – 20 kHz): < 0,1 dB.
- THD: 0,05%.
