Re: high precision adder?

2005-12-19 by selfoscillate

hello dieter,

with the right amount of jacks this module would close a real gap
in the a100 module range. what i always wanted is a buffered
version of an a180 and a precision adder could be used that
way too, if it had enough jacks.

how about three inputs, four buffered outputs and one
inverted output? could be done on a 4 te faceplate.
if you manufacture a module with similar specs, then
i'll buy a minimum of six modules for my system right away.

best wishes

ingo
