The centerpiece for Pultec fans

• Passive, natural-sounding EQ with focus on midrange frequency processing
  
• High class passive circuit design with improved midrange control
  
• Variation of the popular Pultec design
  
• "Air" circuit for high-shelf boosts or attenuations
  
• Requires a pre-amp behind the output, as the passive circuit reduces the level
  
• Can be used with any pre-amp that delivers at least 40dB of gain
  
• Up to 21dB boost at 11 frequencies with variable Q
  
• Up to 17dB attenuation at 11 frequencies with fixed Q
  
• Boost & attenuation also possible at the same time to achieve steeper frequency curves
  
• Extremely low noise and distortion values
  
• Balanced inputs & outputs
