Details About The Power Wattage Specification Of Modern Audio Amplifiers
Considering a number of the technical specifications of modern stereo amplifiers, one cannot help but be at a loss in trying to evaluate different products as well as terms, like "t-amp", "THD" and so forth. I will make clear the term "amplifier wattage" a bit more in this expose. "Power" is one of the most essential terms describing amplifier functioning. However, it is time and again misunderstood. Some makers also in history have used this term in a confusing manner in order to hide the real performance.
If you are looking to buy an audio amp to install your home sound system, you will often be confronted with a number of strange terms describing its performance. But how do these numbers relate to how the amp sounds and how are these to be interpreted? Now I will present various details regarding "amplifier output power". This term is time and again misunderstood. It is essential to look quite closely at how the maker publishes this parameter.
"Wattage" is sometimes also called "Power" or "amplifier output power". To put it in a nutshell, "wattage" indicates how high the amp can drive your speakers. The higher this number the louder your loudspeakers. Depending on your application, you can choose a small amp delivering just a few watts or a larger one delivering several hundred watts. Most home stereos only have amplifiers that have a few watts output power which typically is adequate for a small space. If you intend to shake your walls then you clearly want to choose an amp that has up to a few hundred watts. Please note that many amps will begin clipping the music as soon as the audio reaches higher wattage. If you wish to get pleasure from low-distortion audio then you may wish to pick an amp which will give you higher wattage than you will actually require.
Output power is either given as "Watts peak" which means the amplifier can create brief bursts of this amount of power or "Watts rms" which describes how much wattage the amp can deliver for a longer amount of time. The peak spec has been to some extent abused by manufacturers stating enormous peak audio power whilst their amps are actually constructed with small power supplies unable to handle more than just several watts rms power.
Music and voice is not constant regarding volume. As such the peak power rating is still essential, though not as important as the rms power specification. Ideally the amplifier will show both the rms and peak power rating. Having a high peak power spec will guarantee adequate headroom for power peaks that are widespread in music signals. The most important reason is that audio signals will have short bursts 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.
Typically the impedance of the loudspeakers that you attach to the amp will determine how much power the amplifier may output. Speaker impedance is measured in Ohms. Typically speakers have an impedance between 4 and 8 Ohms. An audio amplifier which has a set 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 amplifier must provide two times the output voltage than when driving a 4-Ohm speaker to be able to output the same amount of wattage. If the maximum power is not referenced to a loudspeaker impedance, you should get in touch with the producer. Typically a 4-Ohm loudspeaker is used as a reference.
