The latest amps appear in all shapes and sizes. Finding the perfect type for your application can frequently be tricky. There is a large number of different names and terms describing audio amps, including "Class D" or "T-amp". What's more, each maker publishes a large amount of specifications, such as "SNR", "dynamic distortion" et cetera. I am going to offer a brief analysis of the output wattage term in order to help you better understand the importance of this specification and how it relates to the functioning of an amp. If you are considering to acquire an audio amp in order to install your home sound system, you will often be confronted with a number of weird terms describing its performance. But how do these numbers relate to how the amp sounds and how are these to be interpreted? Next I will give a few details about "amplifier output power". This specification is time and again misunderstood. It is essential to look quite closely at how the maker shows this rating.
Several of the terms which amp suppliers show regularly are deceptive and do not inevitably offer a good indication of the actual performance of the amp. Now I am going to explain the "output power" rating of power amplifiers. This term is one of the most fundamental and possibly vital specifications to comprehend. "Output power" shows how loud your amplifier may drive your loudspeakers. Based on your application, you may choose a little amp offering merely several watts or a bigger one delivering several hundred watts. Many home radios only have amps which have several watts power which usually is sufficient for a small room. If you intend to shake your walls then you obviously wish to choose an amp that offers as much as several hundred watts. Please note that a lot of amps will start clipping the audio once the audio reaches bigger wattage. If you want to get pleasure from low-distortion audio then you might want to go with an amplifier which is going to give you more wattage than you will really need.
Output power is either given as "Watts peak" which means the amplifier can create brief bursts of this level of power or "Watts rms" which shows how much wattage the amp can deliver for a longer amount of time. The peak output power spec in the past often led to manufacturers showing huge wattage ratings for tiny amplifiers. On the other hand, in practice these amps would not be able to sustain bigger amounts of output power for larger amounts of time.
Nonetheless, while the rms rating is going to tell you more about the amplifier's real performance, be certain though that the amp offers a peak power rating that is quite a bit bigger than the rms rating. This is because very likely you will be using the amplifier to amplify music or voice. Music and voice signals by nature always fluctuate in terms of their power, i.e. the power envelope of the signal is going to fluctuate over time. This is since at certain moments the signal will exhibit peaks of power that by far surpass the average power of the signal.
Please note that often the peak power of the amplifier will depend upon the impedance of your loudspeakers which is commonly between 4 and 8 Ohms. Due to the limited amplifier supply voltage, the highest output power will be half when you attach an 8-Ohm loudspeaker of the peak power which the amp is able to deliver to a 4-Ohm speaker. If the highest power is not referenced to a speaker impedance, you should contact the maker. Typically a 4-Ohm loudspeaker is used as a reference.
