How to Use This Calculator
  1. Enter Level (dBu).
  2. Review the Voltage (Vrms) result.
  3. Use Peak Voltage and Level (dBV) to inform your decision.

How the result changes with Level (dBu)

Level (dBu)Voltage (Vrms)
-680 V
-380.01 V
-20.62 V
2819.46 V

What each input means

Level (dBu)
Audio level in dBu (0 dBu = 0.7746 Vrms). Pro line level is +4 dBu.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Level (dBu) = 4 = 1 input(s) provided
  2. Calculate Voltage
    Voltage
    1.2277 = 1.2277
  3. Calculate Peak Voltage
    Peak Voltage
    1.7362 = 1.7362
  4. Calculate Level
    Level
    1.78 = 1.78
