1; Pop - Sets a 50:1 compression with hard driven limiting in the lowest two bands. The gives a solid bottom to the sound.
2: Hit Radio - Is a compromise between the Universal and Pop settings. You will note that the times are all about the same, with appropriately slower attack and release in the low bands.
