Modern amps appear in all shapes and sizes. Finding the perfect type for your application can frequently be tough. There is a large number of different names and technical jargon describing stereo amplifiers, like "Class D" or "T-amp". Besides, each producer publishes a big number of specifications, such as "SNR", "dynamic distortion" et cetera. In this editorial, I will have a closer look at one of the most basic of these terms: "amplifier output wattage". This term is also often called "wattage".
Some of the technical jargon which amp companies publish regularly are misleading and do not inevitably give a good indication of the true performance of the amplifier. Now I am going to explain the "power" rating of power amplifiers. This term is one of the most fundamental and maybe significant specifications to comprehend.
Output power is either shown as "Watts peak" which means the amp may produce quick bursts of this amount of power or "Watts rms" which describes how much power the amplifier can deliver for a longer amount of time. The peak spec has been to some extent abused by manufacturers stating excessive peak audio wattage whilst their amplifiers are in fact built with tiny power supplies unable to handle more than just several watts rms power.
A few specs will provide the wattage in "Watts peak" whilst some others will publish "Watts rms". "Peak" means that the amp is able to deliver the output power for a brief amount of time only whilst "Watts rms" means that the amplifier is going to constantly provide that level of power. The peak specification has been fairly abused by manufacturers stating excessive peak audio power while their amplifiers are in fact constructed with tiny power supplies unable to handle more than merely a few watts rms power. Still, whereas the rms specification will tell you more about the amplifier's true performance, be certain however that the amplifier has a peak power specification that is substantially higher than the rms spec. This is because most likely you are going to be using the amp to amplify music or voice. Music and voice signals inherently always fluctuate by way of their power, i.e. the power envelope of the audio will vary over time. This is since at specific moments the signal will exhibit peaks of power which by far exceed the average power of the signal.
Please notice that frequently the peak output power of the amp is going to depend upon the impedance of your loudspeakers which is commonly between 4 and 8 Ohms. As a result of the limited amplifier supply voltage, the largest output power will be half if you connect an 8-Ohm speaker of the peak power which the amp may output to a 4-Ohm speaker. If the maximum power is not referenced to a speaker impedance, you ought to contact the producer. Regularly a 4-Ohm speaker is used as a reference.
