Gain Staging & Levels
Convert dBu, dBV, Vrms, and dBFS. Set +24 / +18 / +4 / −10 references. Mic vs line headroom. Watts ↔ volts into ohms. Amp power + sensitivity → SPL at distance.
Use at your own risk. Converter math is exact for the formulas shown; real devices clip, pad, and meter differently. Speaker sensitivity and amp ratings are manufacturer claims — verify on the nameplate and with measurement. This tool is a planning aid only. Always verify against manufacturer documentation and on-site measurements before deploying to a show.

- dBu: 20·log₁₀(V / 0.775) · dBV: 20·log₁₀(V / 1.0).
- dBFS mapping: dBFS = dBu − ref_dBu (where ref_dBu is the analog level defined as 0 dBFS).
- Power: P = V²/R · V = √(P·R).
- SPL: SPL = sensitivity + 10·log₁₀(P_watts) − 20·log₁₀(d_meters) (1 W / 1 m reference, point source).
