Contemplating some of the technical specifications of recent audio amps, one cannot help but be at a loss in trying to compare different types and technical jargon, like "t-amp", "THD" and so forth. In this commentary, I will have a closer look at one of the most elementary of these terms: "amplifier output wattage". This term is also often called "wattage". If you are looking to buy an audio amplifier in order to set up your home sound system, you will often be faced with a number of bizarre technical jargon describing its functioning. But how do these numbers relate to how the amp sounds and how are these to be interpreted? Next I will offer a number of fine points concerning "amplifier power". This specification is time and again misunderstood. It is essential to look fairly closely at how the maker shows this parameter.
Some of the technical jargon which amp suppliers publish often are misleading and do not inevitably offer a decent indication of the real performance of the amp. Now I am going to provide a few details about "amplifier power". This specification is frequently misunderstood. It is essential to look fairly closely at how the maker shows this parameter.
"Wattage" shows how loud your amplifier may drive your loudspeakers. Depending on your application, you may go with a miniature amp offering only several watts or a larger one delivering several hundred watts. Most home stereos only have amps which have several watts power which usually is enough for a small space. If you intend to shake your walls then you clearly wish to opt for an amplifier that offers up to several hundred watts. For superior audio quality, you might wish to pick an amp that has more output power than you need as many amps are going to show increasing distortion once the audio output power increases.
These days most amplifiers are going to specify rms power that offers a better indication of the amplifier's actual performance. Though, please ensure that your amp offers enough headroom to keep away from clipping of the audio. Having sufficient headroom is necessary because audio signals differ a lot from sine wave signals that are used to quantify rms power. Brief bursts of large power are repeatedly found in audio signals. These bursts are going to drive the amplifier into large distortion unless the peak power is high enough.
Please note that frequently the peak output power of the amp will depend upon the impedance of your speakers which is usually between 4 and 8 Ohms. Amplifiers have a limited output voltage swing because of the fixed internal supply voltage. Hence the maximum output power is going to vary depending on the loudspeaker impedance. The smaller the speaker impedance the higher the maximum power the amp may deliver. Regularly highest power is specified for a 4-Ohm speaker impedance. On the other hand, ideally the manufacturer is going to tell which speaker impedance the output power specification is being referenced to. Please note that a number of amplifiers cannot drive speakers with very low speaker impedance.
