Today, API Audio has announced they are upgrading this essential stereo bus compressor and adding a number of new features. The API 2500+ will feature 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.
The Mix/Blend feature allows for either cross fader or parallel mixing of the compressed and uncompressed signal. Engineers can select from three different settings, including OFF (compressed signal only), X (allows the Mix control to adjust between 100% uncompressed to 100% compressed), and II or Parallel (allows the Mix control to dial in compressed signal to blend into the uncompressed signal).
In addition to these new features, the API 2500+ still has the amenities that have made the stereo bus compressor such a beloved piece of gear. The 2500+ features two selectable styles of compression, including "Old" (a feed back style of compression) and "New" (a feed forward style of compression). Also intact is API's patented THRUST circuit for a positively punchy bottom end.
