What does Power: 2x200 Watt RMS mean??

Question

what does the RMS mean? it's about a sound system...

thanks

Answer 1

two channels, 200 watts each, measured in Root Mean Square RMS.

RMS is the best way to measure output power, is is true output and not some made-up lab figure such as IPP Instantanious Peak Power

Answer 2

RMS Power vs. Peak Power

The amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds. When choosing an amplifier, the RMS rating is the power rating you should pay most attention to.

Also, keep in mind that some manufacturers calculate the RMS power ratings of their amplifiers at different input voltages. For example, an amplifier rated at 100 watts RMS at 12 volts can produce considerably more power than an amp rated at 100 watts RMS at the more typical 14.4 volts.

Stereo manufacturers often display peak power ratings on the face of their products. The peak power rating tells you the maximum wattage an amplifier can deliver as a brief burst during a musical peak, like a dramatic drum accent. The RMS figure is more significant.

2x200RMS= two channels that each have 200watts RMS, or if "bridged" (1-channel) 400wattsRMSx1

Bridged Power

When you bridge an amplifier, you combine the power output of two channels into one channel. Bridging allows you to drive one speaker with more power than the amp could produce for two speakers. Because of this high power output, bridging is an ideal way to drive a single subwoofer.
