In nearly every aspect the TRANSIENT DESIGNER is different from conventional Dynamic Processors or Compressors. You don't need to know how the TRANSIENT DESIGNER works in order to be able to use it effectively, but if you're at all curious as to what goes on inside the box, read this section while referring to the diagrams.
