A Good Look At The Expression "Wattage" Of Class T Amplifiers
The latest amplifiers come in all shapes and sizes. Finding the perfect type for your application can frequently be tough. There is a large number of different names and terms describing audio amplifiers, including "Class D" or "T-amp". What's more, each manufacturer publishes a big quantity of specifications, such as "SNR", "dynamic distortion" and so on. In this expose, I will have a closer look at one of the most essential of these terms: "amplifier output power". This term is also often called "wattage". Amp specs are from time to time hard to decipher as they are not completely standardized. Therefore it may be hard to determine the actual performance of the amplifier simply by taking a look at the specs. A good method however is to do a listening trial before purchasing your audio amplifier. Through this trial you ideally wish to set up the amp in a similar setting as your application. Let me now go ahead and describe the wattage rating of stereo amplifiers.
"Power" describes how loud your amplifier may drive your speakers. You wish to choose the audio amplifier wattage based on how large your listening environment is. Most amps will show growing music distortion as output power increases. As a result, you want to go with an amp which offers bigger output power than you will in fact require. This is going to assure that you will never drive the amplifier into areas of high distortion. Several specs will present the power in "Watts peak" while others will publish "Watts rms". "Peak" means that the amp is able to provide the wattage for a brief period of time only whilst "Watts rms" means that the audio amplifier will constantly provide that level of power. The peak spec has been to some extent abused by manufacturers stating huge peak audio wattage whilst their amps are actually constructed with tiny power supplies unable to handle more than just a few watts rms power. Nowadays many amps are going to specify rms power which offers a better indication of the amp's real performance. On the other hand, please make certain that your amplifier has adequate headroom to keep away from clipping of the audio. This is since at specific points in time the signal is going to have bursts of power that by far surpass the average output power of the signal.
Though, be conscious of the fact that the greatest output power also will depend on what kind of loudspeakers you are using, particularly the impedance of the speakers. Loudspeakers typically have impedances between 4 and 8 Ohms. Resulting from the limited amplifier supply voltage, the highest output wattage is going to be half when you attach an 8-Ohm loudspeaker of the peak power which the amp may deliver to a 4-Ohm loudspeaker. Regularly highest power is given for a 4-Ohm loudspeaker impedance. On the other hand, ideally the producer will show which loudspeaker impedance the power rating is being referenced to. Please note that some amps are not able to drive loudspeakers with very low speaker impedance.
