It delivers dynamics control behavior unlike VCA \"feed forward\" compressors so common today. A remarkable multi-function \"ceiling\" control can increase gain reduction (lower threshold) 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 \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 \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. \u003c\/p\u003e\u003cp\u003eOriginally released in the 70's, the API 525 is a \"feedback\" type compressor, such as the 1176 and 660, etc. An input (threshold) control and output (make-up gain) control are provided.
