CH Precision P1 - Stereo Phono Vorverstärker (2x Phono Pre Modul)

Der außergewöhnliche Phono-Vorverstärker CH Precision P1 wird die Quintessenz aller Ihrer Vinyl reproduzieren! Die innovativen Technologien die verwendet werden erlauben ihm das aller Beste aus jeder Tonzelle zu machen.
Alle fabelhaften CH Precision Musikinstrumente werden entwickelt und hergestellt in +Suisse+.

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

Options boards

P1 Enclosure

 p1enclosure

P1 enclosure

The addition of a second P1 enclosure transforms the P1 into a True Monaural phono stage. The power supplies inside each enclosure are devoted to a single channel, further enhancing the noise performances of the system. The units are controlled simultaneously.

EQ
