API 560 – 10-Band Graphic EQ (Demo Unit in Excellent Condition)

This is a demo unit of the legendary API 560 – a classic 10-band graphic equalizer in the 500 Series “Lunchbox” format. This unit is in excellent condition and has been lightly used for demonstration purposes only. It offers the same sonic performance and reliability you’d expect from a brand-new unit, but at a discounted price.

Originally released in 1969, the API 560 was one of the world’s first professional graphic equalizers and remains an industry standard to this day. This modern reissue stays true to the original design, offering unmatched analog EQ shaping with API’s renowned punch, clarity, and warmth.

The API-exclusive “Proportional Q” technology narrows the filter bandwidth at extreme settings, providing musical and accurate tone sculpting whether you’re making subtle adjustments or bold tonal changes.

Ideal for tracking, mixing, or mastering, the API 560 delivers the iconic sound of American analog equalization, making it a powerful tool in any 500 Series rack.
