Eurorack Voltage Levels

Typical Eurorack levels :

All values in [V]

min max peak-to-peak
Audio -5 +5 10
Unipolar CV (Doepfer spec) 0 +8 8
Bipolar CV (Doepfer spec) -2.5 +2.5 5
Unipolar CV (common) 0 +10 10
Bipolar CV (common) -5 +5 10
Gate 0 +5 < 1V : gate is low
>= 3V : gate is high
Trigger 0 +5 < 1 = low
>= 3 = high
Clock 0 +5 same as trigger

Example of unipolar CV : ADSR Example of bipolar CV : LFO
