The API 512c is one of the most famous microphone preamps in studio history and a true classic in the 500 Series. Since its introduction in the 1970s, it has been known for its punchy, warm sound characteristics and is used in countless studios worldwide. Equipped with the legendary API 2520 OpAmp, the 512c offers the full API sound with rich saturation, high transparency and precise dynamic control.

Sound character – clarity, warmth and punch

The API 512c is characterized by its fast, powerful sound with natural warmth. Its high input impedance makes it extremely versatile – whether for microphones, line signals or instruments.

  • Rich analog warmth thanks to the API 2520 OpAmp
  • Excellent detail reproduction, perfect for vocals, guitars, drums and bass
  • Punchy transient processing, ideal for drum recordings

Maximum versatility – microphone, line & instrument inputs

The 512c has three input options:

  • Microphone input (XLR, 48V phantom power) with up to 65 dB gain
  • Line input for external signal sources
  • Instrument input (Hi-Z) for direct recording of guitars, basses and synthesizers

With its stepless gain control, you can precisely adjust the amplification – from subtle level boosts to powerful API saturation.

Professional equipment for flexible applications

In addition to its first-class sound characteristics, the 512c also offers practical features for everyday studio use:

  • Polarity switch (phase reversal) for precise signal processing
  • -20 dB pad for adaptation to high input signals
  • Direct output for parallel signal routing
  • Fully discrete Class A circuit for unadulterated signal processing
  • API 2520 OpAmp – Rich, assertive sound with harmonic API coloration
  • 65 dB amplification
  • Hi-Z instrument input
