Recent amps exist in all shapes and sizes. Finding the ideal model for your application can frequently be difficult . There is a flood of different names and technical jargon describing audio amps, such as "Class D" or "T-amp". What's more, each manufacturer shows a large number of specifications, including "SNR", "dynamic distortion" and so on. I will offer a quick analysis of the output power spec so as to help you better know the significance of this specification and how it relates to the functioning of an audio amplifier.
"Output power" shows how loud your amplifier can drive your speakers. If you own a small space then you don't need much more than several watts. If you want to set up speakers in the open or in a concert then you will require several hundred watts of power. For superior music quality, you may want to go with an amplifier which offers higher output power than you require because many amplifiers are going to exhibit growing distortion once the music output power goes up.
"Wattage" is from time to time also known as "Power" or "amplifier output power". To put it in a nutshell, "wattage" indicates how high the amplifier can drive your speakers. The higher this figure the louder your speakers. Depending on your application, you may choose a tiny amplifier delivering only a few watts or a larger one delivering several hundred watts. Many home radios only have amplifiers that have a few watts power which regularly is enough for a small space. If you intend to shake your walls then you clearly wish to choose an amp that has up to several hundred watts. For best audio quality, you might want to choose an amp which offers more power than you need since most amplifiers are going to show increasing distortion as the music output power goes up.
Power is either given as "Watts peak" which means the amplifier may produce brief bursts of this level of power or "Watts rms" which describes how much power the amp may deliver for a longer amount of time. The peak specification has been to some extent abused by manufacturers showing excessive peak audio wattage while their amps are in fact constructed with tiny power supplies unable to handle more than just a few watts rms power. Nowadays most amps are going to denote rms power which gives a better indication of the amp's true performance. However, please make certain that your amp offers adequate headroom to stay away from clipping of the audio. Having adequate headroom is necessary because music signals differ a lot from sine wave signals that are used to measure rms power. Short peaks of high power are frequently found in music signals. These peaks are going to drive the amplifier into high distortion unless the peak power is high enough.
On the other hand, be conscious of the fact that the maximum output power also depends on which sort of speakers you are utilizing, specifically the impedance of the speakers. Speakers usually have impedances between 4 and 8 Ohms. Amplifiers have a restricted output voltage swing resulting from the fixed internal supply voltage. Hence the largest output power will vary depending on the speaker impedance. The lower the loudspeaker impedance the bigger the maximum power the amp may deliver. If the highest power is not referenced to a loudspeaker impedance, you ought to get in touch with the maker. Usually a 4-Ohm loudspeaker is used as a reference.
