The Mix/Blend feature allows for either cross fade 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 feedback 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.
