dBV

Pedal specifications use it to state nominal input and output levels, maximum input and output levels, noise floors, gate thresholds, and signal to noise ratios¹²³⁴⁵⁶. For example, instrument level inputs are commonly specified around -10 dBV¹², while maximum output levels such as +8 dBV appear on pedals like the MXR M82B Bass Envelope Filter and Carbon Copy Mini Analog Delay⁴⁵. Noise floor figures are also given in dBV, such as -98 dBV for the Dunlop JD4S Rotovibe⁷. The unit can be converted to other level units, as in +7.23 dBV equaling 9.45 dBu or 6.5 Vpp⁸.
