American Equalizer model A v2.0.0

The Model A faithfully captures the punch, low-frequency transparency, and ultra-tight imaging of iconic American EQs of the late 1960’s. Making use of Proportional Q intuitively widens the filter bandwidth at minimal settings and narrows it at higher settings without the need for additional bandwidth controls. This unique feature minimizes the «phase-shift» sound found in many equalizers. 


  • 3 Bands of classic American equalization;
  • Each band offers 7 selected frequency centers;
  • Maximum 12 dB of boost/cut per band;
  • EQ Band 1 and 3 offer Shelf/Peak switching;
  • Proportional Q narrows filter Q at extremes;
  • Stereo (Mono), Mid or Side EQ Modes.

The Model A provides reciprocal equalization at 21 points in 5 steps of boost to a maximum of 12dB of gain at each point. The 21 equalization points are divided into three overlapping ranges. The high and low frequency ranges are individually selectable as either Peaking or Shelving, and a Band-Pass Filter may be inserted independently of all other selected equalization settings. Frequency ranges and boost/cut are selected by switches, and a pushbutton IN switch allows the EQ to be silently introduced to the signal path. A small toggle switch is used to insert the Band-Pass Filter into the Model A.

The Model A extends the features of the original hardware and joins the flexibility of the digital world to the character of the analog processing. Allows you to choose between equalizer Modes (Stereo, Mid, Side) and remove Analogue Saturation from the processing circuit to deliver pure digital sound.
