{"product_id":"api-525","title":"API 525 500 Series Compressor","description":"\u003cp\u003eThe \u003cspan style=\"font-weight: bold;\"\u003eAPI 525\u003c\/span\u003e, originally released in the 70s, is a feedback type compressor, such as the 1176 and 660, etc.  An input control and output control are provided.  An additional ceiling fine tune function modifies threshold and make-up gain for precise changes in compression without changes in output.  A compression\/limit switch sets ratio at either 2:1 or 20:1.  Attack time is as fast as 15u\/s.  Four auto release modes are offered via two switches, 0.1s, 0.5s, 1.5s \u0026amp; 2.0s.  A de-ess function inserts an inverse vocal energy curve filter in the detector for effective sibilance\/p-pop reduction.  The 525 is an identical re-issue of one of the most popular API products ever.\u003c\/p\u003e\r\n\u003cp\u003eThe API 525 is perhaps the most successful solid state feedback compressor in history.  It delivers dynamics control behavior unlike VCA feed forward compressors so common today.   A remarkable multi-function ceiling control can increase gain reduction while simultaneously raising output level to match, so the user can alter dynamics on the fly without level changes.  This re-issue design has been taken from the original blue prints and spec control drawings from the API archives.\u003c\/p\u003e\r\n\u003cp\u003eRelease times vary with frequency, with high frequency\/full bandwidth content released faster than just low frequency for natural envelope tracking.  Attack time is fixed, chosen to catch the fastest peaks without pumping.  Equally useful as a tracking, mixdown or program compressor\/limiter, the benefits of the API 525 are most obvious to those who use compression on a regular basis.  Vintage dynamics control, an easy-to-use multi-function control set and a wide range of 500 Series mounting options assure that the 525 will surpass your most critical applications.  With the addition of a hard-wire bypass switch, a balanced input and a pinout that is the same as all the other 500 series modules, the 525 is still, after 25 years—\"the sound.\"  Two or more 525s can be linked for multi-channel compression.\u003c\/p\u003e\r\n\u003cp\u003eThe 525 feedback compressor\/limiter makes use of the 2510 and 2520 op-amps and therefore exhibits the reliability, long life and uniformity which are characteristic of API products.\r\n\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e","brand":"API Audio","offers":[{"title":"Default Title","offer_id":44449237991527,"sku":"755","price":1295.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/api_525_5_3021f404-adcb-469a-99b5-c7bc2ca9fdbf.jpg?v=1787088262","url":"https:\/\/vintageking.com\/products\/api-525","provider":"Vintage King","version":"1.0","type":"link"}
