I agree with Lonman. It is basic compression. However, DBX invented the technology. It is far superior to any other. They also invented the over-easy knee. It is much better for vocals. Behringer mixers are not very high quality. Their speakers and amps are above average. Look at a Allen&Heath ZED series mixer. Worth every penny. If you are a professional, you should invest in yourself to get quality equipment. It will last years and years. An extra hundred or two now will make your life easier down the road.
