Classic semi-parametric EQ based on the original Studer 169 console circuit topology, mastered with innovative features, including:

• Fully stepped 11-positions switches behind each knob

• High Pass Filter
  
  • Innovative "Low-Resonance" design for great musicality
  • 11 tuned frequencies: 12 | 16.4 | 20.6 | 25.0 | 30.9 | 42 | 55 | 78 | 110 | 160Hz
  • Bypass position

• EQ Frequencies
  
  • High Pass Filter: 10 tuned frequencies, ranging from 12 to 160Hz + bypass
  • High Shelf: 20kHz (original) or 35kHz
  • "Presence" filters: 22 values distributed from 150 to 7.000Hz - Q ≈ 1.0
  • Low Shelf: 20Hz (original) or 60Hz

• EQ gain modes
  
  • Standard mode: ±12dB on Presence | ±15dB on Shelves
  • Hybrid mode: ±12dB on Presence | ±5dB on Shelves
  • Mastering mode: ±4dB on Presence | ±5dB on Shelves

• Output Gain Trim: ±3dB in 0.5dB steps

• Transformerless input & output for a transparent sound
• Relay operated bypass circuit

• Max level (input & output) : +22dBU
• Input impedance: 48kΩ
• Output impedance: 50Ω

• 0.005% THD @ 0dBU
• Frequency response (1kΩ load): ±0.1dB from 5.4Hz to 25kHz+ (our Audio Precision can't measure above 25kHz ☺️)
• SNR: >108dB
• Gain matching between units: ±0.1dB

Designed and assembled in our workshop in Saint-Vérand (France). All parts are manufactured by our beloved partners in France & Europe.
