What is RMS (continuous) power output?
In general terms, RMS is an indication of the average continuous output of an amplifier. More specifically, “continuous power output” is a measurement of the power output of one channel into a specified load (typically 4 ohms) below a certain distortion level (usually 1%THD or less) at a certain frequency (usually 1kHz). An amplifier should be able to sustain the continuous power output level for extended periods of time without problems such as overheating. The best measure of an amplifier’s power is its continuous power rating.
