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
