API 560 500 Series EQ

Originally designed for use in API consoles of the 1960s and 1970s, the API 560 reissue is a distinctive device with capabilities that set it apart from other EQs. It captures the unique API sound, offering precision easy-set filtering and high headroom in a compact package. With accurate zero detents, the 560 is exceptionally fast to set and reset, providing unmatched curve-shaping potential. This "new-old" version is a reissue of the original 560, featuring improved resolution in the critical area of ±4 dB. Incorporating API's exclusive circuitry and proprietary components, including the legendary 2520 op-amp, the reissue skillfully blends the past with the present, merging layout with function.

Originally created to meet the diverse needs of professional engineers, the API 560 was a staple in remote recording consoles manufactured by API throughout the 1970s and 1980s. It excels in both studio and live sound applications, delivering professional results. The reissued design closely follows the original blueprints and specification control drawings from the API archives.

With its numerous EQ bands, the 560 is an ideal companion to parametric EQ and is well-suited for signal sweetening and room tuning. Making use of API's unique "Proportional Q" design from the 1960s, the 560 intuitively widens the filter bandwidth at lower boost/cut levels and narrows it at higher settings. Boost and cut characteristics are identical, allowing for easy reversal of previous actions.

The exceptional headroom provided by API's proprietary 2520 op-amp ensures predictable and superb "analog" performance under pressure. With a broader range of 500-series mounting options, the 560 is a valuable asset for performance-critical applications.

The API 560 Graphic Equalizer utilizes the reliable 2510 and 2520 op-amps, reflecting the reliability, long life, and uniformity characteristic of API products.
