The Industry Leader In Affordable Analog Products

Pro-Ject Audio Systems was founded by one of Austria’s leading high-end audio distributors, Heinz Lichtenegger, in early 1991. A genuine music lover and a dyed-in-the-wool audiophile, Heinz challenged the common “cost-no-object” approach to analog audio equipment by manufacturing turntables, tonearms, and accessories at a reasonable price without compromising build quality or sonic performance.

• Selection between two phono inputs & two line outputs
• Dual mono circuitry for optimized channel separation
• Selectable input impedance (for MC: fixed or variable)
• Selectable input capacitance (for MM)
• Selectable subsonic filter
• Gold-plated RCA in & outputs
• Sandwich alu/metal casing protects from vibrations and electromagnetic interference
• Available in silver or black with or without side panels in Eucalyptus, Rosenut or Walnut
