The API 527A takes it’s place alongside the family of API VCA based compressors, the 225L and the 2500 Stereo Bus Compressor. Features common to the line like “feed forward” (NEW) and “feed back” (OLD) gain reduction methods selectable on the front panel, provide a choice of “that old way”, or “the new way” of compression, for the highest level of flexibility in signal gain control.

The API 527 is designed for individual channel use or, through the use of the LINK switch, two units can be combined for Stereo applications via a motherboard bus connection.
