Considering a few of the technical specifications of modern audio amplifiers, one cannot help but be at a loss in attempting to compare different models and technical jargon, such as "t-amp", "THD" and so forth. In this expose, I will have a glimpse at one of the most elementary of these terms: "amplifier output power". This term is also known as "wattage".
Amplifier specs are at times tricky to understand as they are not completely standardized. As such it can be tricky to discover the actual performance of the amplifier simply by taking a look at the specifications. A good method though is to do a listening test ahead of purchasing your power amplifier. Throughout this trial you ideally want to install the amplifier in a comparable setting as your use. Now I am going to explain the "wattage" spec of power amps. This rating is one of the most essential and perhaps essential specs to understand.
"Wattage" is every now and then also called "Power" or "amplifier output power". To put it in a nutshell, "wattage" relates to how high the amp can drive your loudspeakers. The higher this number the louder your loudspeakers. You wish to pick the audio amplifier wattage depending on how large your listening environment is. Please note that numerous amps will start distorting the audio as soon as the audio reaches higher wattage. If you wish to get pleasure from low-distortion audio then you may want to go with an amplifier which will give you higher wattage than you will actually require.
There are two widespread methods to publish amplifier wattage. These are "peak power" and "rms power". "Peak power" shows how much power the amp may deliver to your speakers for a brief burst. On the other hand, "rms power" describes how much power the amplifier can output for a longer amount of time without being damaged. The peak spec has been fairly misused by vendors showing enormous peak audio wattage whilst their amplifiers are actually built with small power supplies unable to handle more than only several watts rms power. Music and voice is not constant by way of loudness. As such the peak power rating is still important, though not as essential as the rms power spec. Ideally the audio amplifier will show both the rms and peak power rating. Having a high peak power spec will guarantee adequate headroom for music peaks that are common in music signals. The most important reason is that audio signals are going to have short peaks of high power that the amplifier has to deal with. Rms power is measured with a uniform sine signal that hardly compares with a music signal in terms of the power envelope.
Usually the impedance of the speakers which you attach to the amplifier will determine how much power the amp may offer. Speaker impedance is measured in Ohms. Typically loudspeakers have an impedance between 4 and 8 Ohms. An audio amplifier that has a fixed internal supply voltage is going to have a maximum output voltage swing that is restricted by that supply voltage. If you are driving an 8-Ohm speaker then the amp must output two times the output voltage than when driving a 4-Ohm speaker in order to deliver the same level of output power. As a consequence often highest output power is given for a particular speaker impedance.
