MOTM

What does one do for additional attenuation in the MOTM world? Most 
modules seem to have at least one input with no control and none (I 
think) have output controls. I prefer the convention with no output 
level controls and all input level controls (except v/8va inputs). I 
understand that this is a trade off between circuit functionality, 
panel real estate and module conventions - but, if this is truly a 
"modular" system - where is the attenuator module? There needs to be 
an alternative to burning a mixer (or half a mixer) to control an 
input. Also, is there a down side to passive attenuation? (no pun 
intended)

Tomorrow's question: where's the damn inverter? ;-)
