Gain-Staging Calculator
Convert between dBu, dBV, and Vrms, chain gain stages together across a signal path, and see exactly how much headroom you have left before clipping.

Why this matters: Consumer (-10dBV) and professional (+4dBu) gear differ by about 11.8 dB in nominal level — connecting the two directly without a level-matching device (a DI box, transformer, or dedicated converter) means one side runs too hot or too quiet.
