Selecting the ideal model is not easy whilst faced with a big array of different technical jargon plus specifications, such as "T-amp", "channel separation", "efficiency" and so on. You might not even fully comprehend the most simple of these terms, for example "amplifier power". I will give a short summary of the output power spec to help you better comprehend the significance of this term and how it relates to the functioning of an audio amplifier. Some of the technical jargon which amp suppliers make public often are misleading and do not necessarily provide a good indication of the real functioning of the amp. Next I am going to explain the "power" spec of power amplifiers. This specification is one of the most essential and maybe vital specs to comprehend.
"Wattage" is from time to time also known as "Power" or "amplifier output power". To put it in a nutshell, "wattage" relates to how high the amp can drive your speakers. The higher this figure the louder your speakers. You wish to pick the amp wattage based on how large your listening environment is. For best audio quality, you may wish to pick an amp which has bigger output power than you require because many amplifiers are going to exhibit growing distortion once the audio output power goes up.
"Wattage" is sometimes also known as "Power" or "amplifier output power". To put it in a nutshell, "wattage" relates to how high the amplifier can drive your loudspeakers. The higher this number the louder your speakers. Based on your application, you may choose a tiny amp delivering only a few watts or a larger one offering several hundred watts. Most home stereos only incorporate amplifiers that have several watts power which regularly is adequate for a small room. If you plan to shake your walls then you obviously want to choose an amplifier that has as much as a few hundred watts. For best audio quality, you may want to go with an amp which has more output power than you need as many amps are going to show increasing distortion once the music power increases.
Various specs will give the power in "Watts peak" while some others are going to exhibit "Watts rms". "Peak" means that the amplifier is able to deliver the output power for a brief period of time only while "Watts rms" means that the amp is going to continuously provide that amount of power. In the past, vendors have typically favored showing the "peak power". This number is bigger than the average or "rms" power. However, "peak power" can often be deceptive since there is no standard stating the period of time that the amp has to be able to deliver this amount of power. Today most amps will specify rms power that gives a better indication of the amp's actual performance. Though, please make certain that your amp offers sufficient headroom to stay away from clipping of the audio. Having enough headroom is vital as audio signals differ a lot from sine wave signals which are used to quantify rms output power. Brief bursts of high power are repeatedly found in audio signals. These bursts will drive the amplifier into high distortion unless the peak power is big enough.
Please note that frequently the peak output power of the amp is going to depend on the impedance of your speakers which is commonly between 4 and 8 Ohms. As a result of the limited amplifier supply voltage, the maximum output power will be half when you attach an 8-Ohm speaker of the peak power which the amplifier can deliver to a 4-Ohm loudspeaker. Regularly maximum output power is specified for a 4-Ohm loudspeaker impedance. Though, ideally the manufacturer is going to show which loudspeaker impedance the power rating is being referenced to. Please note that some amps are not able to drive speakers with extremely low loudspeaker impedance.
