API 2500+ Stereo Bus Compressor

API

API's flagship stereo bus compressor. Discrete signal path through API 2510 + 2520 op-amps — the same chips in 550A EQs and the entire Vision console. The THRUST circuit filters low frequencies out of the detector path so kicks and basses don't duck the rest of the mix — gives you the API "punch" sound without sacrificing low-end. Variable link from independent to 100% lets you preserve stereo image while still bus-compressing.
