It's not in the manual. They are two different types of DSP filters. I 
think FIR has slightly less ringing, but IIR has...something else. 
Anyway, some people may prefer the sound of one to the other.

This wasn't supposed to be a permanent user interface, I think. Anyway 
this parameter only relates to the DSP, not to the crystal filter.

It doesn't matter which filter you have selected. Just go to the filter 
bandwidth parameter and hit 7 until you see IIR ON.
