Maybe it's a little dumb question, maybe I could figure it out from descriptions on the Bag End site. But still: what is the practical way to use ELF processors/speakers with other bass amplification equipment? For example, if I want to use it to reproduce the suboctave, generated by some bass amp, such as Ashdown Magnifiers. As I understand, the suboctave is generated in its preamp. And as I understand, an ELF processor must be inserted before the PA section. So does this mean it can be run in the effects loop??? Or what else? Or, say, the sub signal is suggested to go from the special sub output of the Ashdown to the ELF processor, and then into a separate PA?
