Decibels referred to 1 volt.
A logarithmic voltage reference point equal to 1.0 Vrms.
The voltage relative 0 dBV. 0 dBV is defined as 1.000V, (e.g. 4 dBV = 1.585 V). /p /p
a means of expressing voltage, referenced so that 0 dBV equals 1-volt RMS, regardless of impedance.
synonymous with dBu, but rarely used due to confusion with dBV. See dBu.
dB referenced to 1.0 Vrms. -10dBV is a standard audio line level for consumer and some professional audio use, equal to 0.316 Vrms. RCA audio connectors are a good indicator of units operating at -10 dBV levels.
