API 560

API 560 10-Band Graphic Equalizer – 500 Series

The API 560 is a reissue of the iconic 1969 graphic equalizer, one of the first of its kind and still a benchmark for musical EQ shaping today. Designed in the popular 500 Series „lunchbox‟ format, the API 560 delivers 10 bands of precision equalization with API’s legendary analog warmth, headroom, and reliability.

Each band provides ±12 dB of boost or cut on fixed, one-octave frequency centers, using a familiar slider-based graphic interface for fast and intuitive operation. At the core of the 560 is API’s renowned Proportional Q design, which automatically narrows the bandwidth of each band as boost or cut is increased — allowing for detailed, surgical adjustments or smooth, broad tonal shaping depending on your needs.

The API 560 also features center-detented sliders for easy recall and precise zeroing, enhanced resolution in the ±4 dB range for fine-tuned settings, and a silent bypass switch for quick A/B comparisons. Built with API’s signature discrete circuitry and 2520 op amps, the 560 offers unmatched headroom and clarity, making it an excellent choice for everything from vocals and instruments to mix bus and mastering duties.
