What is dBV?
“dBV” stands for “decibel Volt”, and it is used to express voltage in dB units. dBV represents voltage using a logarithmic scale based on a reference of 1 Volt (V), and it is measured in terms of RMS (Root Mean Square).
A value of 0dBV corresponds to a reference voltage of 1 Volt. Positive dBV values indicate voltages higher than the reference, while negative dBV values denote voltages lower than the reference.
