Taking a look at several of the technical specifications of recent power amplifiers, one cannot help but be at a loss in attempting to compare different products and terms, e.g. "t-amp", "THD" et cetera. I will present a brief summary of the output power specification so as to help you better understand the meaning of this specification and how it relates to the functioning of an power amplifier. If you are looking to buy an audio amplifier to set up your home sound system, you will time and again be confronted with a number of bizarre terms describing its performance. However how do these numbers relate to how the audio amplifier sounds and how are these to be interpreted? Next I will offer a few fine points concerning "amplifier power". This rating is time and again misunderstood. It is important to look fairly closely at how the producer publishes this rating.
The output power of the amps is given as "wattage". This describes how loud your amplifier can drive your speakers. Depending on your application, you can go with a tiny amp offering merely several watts or a larger one offering several hundred watts. Most home radios only come with amplifiers which have a few watts output power which regularly is sufficient for a small room. If you intend to shake your walls then you obviously want to opt for an amplifier that has up to several hundred watts. For superior audio quality, you might want to go with an amp which has higher output power than you require since most amps will exhibit rising distortion once the music power increases.
"Wattage" is every now and then also known as "Power" or "amplifier output power". To put it in a nutshell, "wattage" relates to how high the amplifier can drive your speakers. The higher this figure the louder your loudspeakers. If you own a small room 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 show then you will require several hundred watts of power. For best audio quality, you may want to go with an amp that offers more power than you require as most amplifiers are going to exhibit rising distortion once the audio output power goes up.
Nowadays many amplifiers will specify rms power that provides a better indication of the amp's actual performance. However, please make certain that your amplifier offers adequate headroom to keep away from clipping of the audio. This is since at specific points in time the signal will exhibit peaks of power which by far exceed the average power of the signal.
Typically the impedance of the speakers which you attach to the amplifier is going to determine how much power the amp may offer. Speaker impedance is measured in Ohms. Usually loudspeakers have an impedance between 4 and 8 Ohms. An audio amplifier that has a set internal supply voltage is going to have a maximum output signal swing which is restricted by that supply voltage. If you are driving an 8-Ohm speaker then the amp has to deliver twice the output voltage than whilst driving a 4-Ohm speaker so as to output the same amount of wattage. Consequently frequently highest output power is shown for a particular speaker impedance.
