Serge NTO

Technical Aspects:

• 

Use antistatic precaution when handling the NTO pcbs - don’t touch the small SMD parts and ICs with 
your hands.

• 

Only these parts have to be soldered in: 4 trimpots on the main pcb, an (optional) 470nF or 1uF film 
capacitor on the panel pcb, 5 pin stripes to connect the main pcb to the panel pcb, Euro power 
header. 

• 

Traditionally the Portamento knob was wired so that fully clockwise there was no(!) portamento effect 
while CCW meant maximum. You may find this counter-intuitive, so you can set the pot behavior using 
2 jumpers: vertically means classic Serge-style, horizontally means modern (turning the knob up means 
more effect). 

You have to set the jumpers one way or the other to be able to use the knob
