So, I've got a client who has an API 2500 that has a uneven stereo image. Tried adjusting the tilt pot but it didn't give me the desired affect for getting the whole compressor even with itself. I'm having him check to see if he's still under warranty first. But if not I'll probably end up trying to calibrate this thing. Just wanted to check here first and see if anyone has successfully calibrated one of these things. So that at least have a place to start. Thanks!
