The Level Meter displays both the current peak signal level and the current Root Mean Square (RMS) signal level.
The peak signal meter displays the highest energy or loudness level that the input signal reaches. The RMS signal meter measures the energy or loudness of a signal and samples the true Root Mean Square signal level.
Two hold indicators, peak hold and RMS hold, indicate the maximum levels that were reached over a specified, or infinite, period of time.
This meter is useful for measuring the dynamic range of a signal. The peak meter is especially useful when adjusting levels through a signal path to accurately indicate the headroom available.
