Technische Eigenschaften:
Modularity:
Two P1 configurations are available:
- Dual Monaural (two channels in a single enclosure)
- True Monaural (each channel in its own enclosure)
Moving coil current inputs:
The P1 provides two moving coil current inputs, featuring the following specifications:
- inputs specifically designed for low output, low internal resistance MC cartridges
- current mode for best signal to noise ratio when paired with low output MC cartridges
- no impedance adjustment required in current mode
- XLR and RCA connector available on each input
Moving magnet / moving coil voltage input:
The P1 provides a more classical voltage input, featuring the following specifications:
- input designed for MM, MC cartridges and step-up transformers
- ultra low noise FET-input stage
- cartridge loading adjustment, variable from 100k Ohms to 20 Ohms in over 500 steps
- wizard to select the cartridge's optimal loading through frequency response automated analysis
- XLR and RCA connections
EQ curves:
- RIAA and enhanced RIAA (with additionnal Neumann pole) EQ curves factory fitted
- high grade, tight tolerance custom components
- optional add-on board containing EMI, Columbia, Decca and Teldec EQ curves
Analog signal path:
- selectable high-pass subsonic filter to remove unwanted rumble
- ultra low noise, high bandwidth, high slew rate design
- class A, discrete transistor based design
Power supply:
- ultra low noise, high accuracy, discretely regulated linear power supplies
- oversized mains toroidal transformers
- shunt regulators for all stages
- can be powered from the X1 External Power Supply unit
