Root-mean-square. For a sine wave, RMS voltage is measured as the peak to peak voltage divided by 2 then multiplied by 0.707. In essence, RMS calculations are developed from continuous power output measurements to each channel of an Altec Lansing speaker system. Each channel's RMS is then added together to develop the Total System RMS power measurement. This measurement contrasts with the term Total System Power, measured on initial bursts of power output at the beginning of the measurement period, and which is of very short duration. Because of the inherent qualities of power amplifiers, these initial bursts often achieve amplitudes of much greater dimension than those sustained results on which RMS is calculated. Total System Power measurements tend to be much higher than RMS. RMS measures overall, realistic, sustained system power.
A term used to indicate the average level of power that a receiver or amplifier can sustain over a given period of time. Average power ratings (ex: 100 watts RMS) provide a more realistic assessment of your amp's performance than peak power (ex: 400 watts peak/dynamic power) since an amp can only sustain peak power for a short period of time. (RMS stands for "root mean square," which is one of the mathematical methods used to calculate an amp's average power output. While it isn't an accurate descriptor of the measurements themselves, it's commonly used throughout the industry to denote the average power rating.)
