 About

SumDif is a dual adder / 
differentiator module 
capable of handling both CV 
and audio signals. If you 
send a 3V signal at the A 
input and a 1V signal at the 
B input, then the A+B will 
output 4V while A-B will 
output 2V. Numerous 
applications, like unity 
mixing, buffering and 
inverting, can be achieved; 
you can also experiment 
with Mid/Side audio proces-
sing ! The SumDif has a 
precision signal path and 
can process V/oct signals 
perfectly. The two jumpers 
on the back side allow  to 
reduce the A+B and A-B 
outputs gain by 6dB.
