Considering a number of the technical specifications of recent audio amplifiers, one cannot help but be at a loss in trying to compare different models as well as technical jargon, such as "t-amp", "THD" and so forth. I am going to present a brief summary of the output power term so as to help you better appreciate the importance of this term and how it relates to the functioning of an audio amplifier. If you are looking to buy an audio amp to install your home sound system, you will often be confronted with a number of weird terms describing its performance. However how do these numbers relate to how the amp sounds and how are these to be interpreted? Now I will give various fine points regarding "amplifier wattage". This specification is time and again misunderstood. It is essential to look fairly closely at how the maker publishes this rating.
"Wattage" is every now and then also known as "Power" or "amplifier output power". To put it in a nutshell, "wattage" shows how high the amp can drive your speakers. The higher this number the louder your loudspeakers. You want to choose the amp wattage based on how large your listening space is. Many amps will show increasing audio distortion as output power increases. Consequently, you wish to pick an amplifier that offers more output power than you will actually require. This will guarantee that you will never drive the amplifier into areas of high distortion.
"Wattage" shows how loud your amplifier can drive your speakers. If you have a small room then you don't require much more than several watts. If you want to set up speakers in the open or in a live concert then you will need several hundred watts of power. Most amps will show growing music distortion as output power increases. As a result, you wish to pick an amplifier which has more output power than you will in fact require. This will guarantee that you will never drive the amplifier into regions of big distortion.
Nowadays many amplifiers will state rms power that provides a better indication of the amp's real performance. On the other hand, please ensure that your amp offers adequate headroom to stay away from clipping of the audio. Having sufficient headroom is vital given that music signals differ a lot from sine wave signals which are used to determine rms power. Short bursts of large power are often found in music signals. These bursts are going to drive the amp into high distortion unless the peak power is big enough.
Though, be aware of the fact that the largest output power also depends on which type of loudspeakers you are utilizing, particularly the impedance of the speakers. Loudspeakers usually have impedances between 4 and 8 Ohms. Amps have a restricted output voltage swing resulting from the fixed internal supply voltage. As such the largest output power will vary depending on the loudspeaker impedance. The smaller the speaker impedance the bigger the highest power the amplifier can output. Accordingly frequently maximum output power is given for a certain speaker impedance.
