The API Select T25 is a two-channel FET feedback-style compressor using a Class-A tube output stage and API transformer.
The API Select T25 uses both 12AT7WC and 12BH7 vacuum tubes followed by a custom API transformer. It also features APi’s patented Thrust control for frequency dependent side-chain control and avoiding excessive low-end triggering the compressor as well as a D-S button for high-frequency dependent compression (such as de-essing). It can work as two mono channels, or stereo compression at the press of a button.
