The latest amplifiers come in all shapes and sizes. Finding the ideal type for your application may frequently be tough. There is a flood of different names and terms describing stereo amps, like "Class D" or "T-amp". Besides, each manufacturer publishes a huge number of specifications, including "SNR", "dynamic distortion" and so on. In this editorial, I am going to have a glimpse at one of the most essential of these terms: "amplifier output power". This term is also often known as "wattage".
A number of of the technical jargon which amp producers make public frequently are deceptive and do not inevitably give a good indication of the actual functioning of the amp. Next I am going to describe the "power" spec of stereo amplifiers. This spec is one of the most essential and perhaps vital specs to understand. The output power of the amplifiers is given as "wattage". This shows how loud your amp may drive your speakers. If you own a small space then you don't require much more than a couple of watts. If you wish to install speakers in the open or in a live concert then you will require several hundred watts of power. Please note that a lot of amplifiers will begin distorting the audio once the audio reaches higher wattage. If you want to enjoy low-distortion audio then you might want to go with an amplifier that is going to give you more wattage than you will actually need.
Output power is either shown as "Watts peak" which means the amplifier may produce short bursts of this amount of power or "Watts rms" which describes how much power the amp may offer for a longer period of time. The peak spec has been fairly abused by vendors stating excessive peak audio wattage whilst their amps are in reality developed with tiny power supplies unable to handle more than merely a few watts rms power.
Music and voice is not uniform regarding volume. As such the peak power rating is nonetheless significant, although not as important as the rms power spec. Ideally the amp is going to publish both the rms and peak power rating. Having a large peak power spec is going to guarantee enough headroom for audio peaks that are widespread in audio signals. Having enough headroom is crucial given that music signals differ a great deal from sine wave signals which are used to measure rms power. Brief bursts of high power are often found in audio signals. These peaks will drive the amplifier into large distortion unless the peak power is high enough.
Usually the impedance of the loudspeakers that you attach to the amplifier is going to determine how much power the amplifier may output. Speaker impedance is measured in Ohms. Usually speakers have an impedance between 4 and 8 Ohms. As a result of the limited amplifier supply voltage, the maximum output power will be half when you connect an 8-Ohm speaker of the peak power which the amp is able to output to a 4-Ohm loudspeaker. Regularly highest output power is given for a 4-Ohm speaker impedance. However, ideally the manufacturer will show which speaker impedance the output power spec is being referenced to. Please note that some amplifiers are not able to drive loudspeakers with very low loudspeaker impedance.
