The API 560 was originally conceived for use in API consoles of the 60's and 70's.  The API 560 re-issue is a unique device designed to accomplish tasks that no other EQ can do. It delivers that "one-of-a-kind" API sound, precision easy-set filtering and high headroom in a very small package. Extremely fast to set and reset using accurate zero detents, the curve-shaping potential of the 560 is unmatched. At home both in field recording and the studio environment, this "new-old" version is a re-issue of the original 560 with improved resolution in the critical area of ±4 dB. Incorporating API's exclusive circuitry and proprietary components (such as the legendary 2520 op-amp), the re-issue of the 560 artfully blends the past with present—layout with function. The API 560 was created to fit all applications for the professional engineer. For most of the 70's and 80's, every remote recording console that API manufactured used this versatile graphic EQ. It is also ideal for studio and live sound applications, where a professional result is required. This re-issue design has been taken from the original blueprints and spec control drawings from the API archives. The large number of available EQ bands makes the 560 an ideal companion to parametric EQ, as well as ideal for signal sweetening and room tuning. Not lacking in features, the 560 makes use of API's unique "Proportional Q" design introduced by API in the 60's, intuitively widening the filter bandwidth at lower boost/cut levels and narrowing it at higher settings. In addition, boost and cut characteristics are identical, so previous actions can be undone. The extraordinary headroom made possible with API's proprietary 2520 op-amp offers predictable and wonderful "analog" performance under duress. With a wider range of 500-series mounting options, the 560 will be a valuable asset to your performance-critical applications. The 560 Graphic Equalizer makes use of the 2510 and 2520 op-amps and therefore exhibits the reliability, long life and uniformity which are characteristic of API products. Features 10 bands of API proprietary equalization Familiar graphics operation on one-octave centers 12 dB of boost/cut per band "Proportional Q" narrows filter Q at extremes Additional resolution within the ±4 region Center detent for reliable reset Traditional API fully discrete circuit design Silent bypass switch Re-issue of the 1969 API 560 EQWARRANTY New Gear Free Extended Warranty If it's available at Vintage King, we add one year to the manufacturers' warranty FREE.
