It sounds like its using a technique (also employed by the 'loudness' button on stereos) whereby the lower and upper frequencies are boosted to produce a psychoacoustic effect that increases apparent loudness. If the overall level was kept the same, the midrange would suffer.Fernando b very carefull with the BBE I have found that it can have a positive feel but U have 2 really ease up on the param. otherwise it kills a lot of the midrange....
It's probably better to do this yourself, so you can play the EQ more musically.
