In December 2000, a 7” long axial crack was visually identified on the compressor rear frame of an LM2500 propulsion gas turbine engine aboard the USS MITSCHER (DDG 57).

The result is chest-thumping low end and a stronger mid-range. This selectable filter puts a low-cut, high-boost EQ into the audio signal, which ultimately allows the compressor to focus less on lower frequency sounds in the mix.

To achieve the aforementioned punch on the low end, API has included its patented THRUST circuit on the stereo bus compressor. When it comes to the styles of compression, users are able to choose between “old” and “new.” Old style employs the “feed back” compression of the API 525, while the new style gives a “feed forward” compression feeding the side chain directly from the input. For many, the API 2500 has become the industry standard, as the discrete compressor offers you the ability to glue together mixes via two distinct styles of compression and add punch to the low end.ĪPI 2500 features a dual-channel design that can be used individually for single-channel compression or paired together in tandem for stereo use.

Update March 2020: API Audio has announced an expanded 2500+ stereo bus compressor with updated features, including an Expanded Threshold control (+20dv to -20dv) and the new Mix/Blend function that was added to the 50th Anniversary Edition of the 2500 released last year.
