Comparing Several Miniature Amplifiers By The Power Level
Selecting the perfect type is easier said than done whilst confronted with a huge array of different terms plus specifications, like "T-amp", "channel separation", "efficiency" et cetera. You may not even fully comprehend the most simple of these terms, for example "amplifier power". I will provide a quick analysis of the output power spec so as to help you better understand the importance of this specification and how it relates to the functioning of an audio amplifier.
Amplifier specifications are at times hard to interpret since they are not completely standardized. As such it may be tricky to understand the true functioning of the amp just by focusing on the specs. A good method however is to do a listening test prior to purchasing your amplifier. Throughout this trial you ideally want to install the amplifier in a similar setting as your application. Now I will give some details about "amplifier output power". This spec is frequently misunderstood. It is vital to look quite closely at how the manufacturer publishes this rating.
"Wattage" shows how loud your amp may drive your loudspeakers. Based on your application, you can go with a miniature amplifier delivering only several watts or a larger one delivering several hundred watts. Many home stereos only incorporate amps which have several watts power which usually is adequate for a small space. If you intend to shake your walls then you obviously want to choose an amp that has up to several hundred watts. Please note that numerous amps will start clipping the music once the audio reaches bigger wattage. If you want to enjoy low-distortion music then you may want to pick an amp which will give you higher wattage than you will actually need.
Power is either given as "Watts peak" which means the amplifier may create quick bursts of this level of power or "Watts rms" which describes how much wattage the amp can offer for a longer period of time. The peak spec has been to some extent abused by manufacturers stating enormous peak audio power while their amplifiers are in reality constructed with very small power supplies unable to handle more than merely a few watts rms power.
Nowadays many amplifiers will denote rms power that provides a better indication of the amplifier's actual performance. Though, please ensure that your amplifier offers enough headroom to keep away from clipping of the audio. Having enough headroom is vital because music signals differ a great deal from sine wave signals which are used to determine rms output power. Brief peaks of high power are repeatedly found in audio signals. These bursts are going to drive the amp into high distortion unless the peak power is high enough. Typically the impedance of the loudspeakers that you connect to the amplifier is going to determine how much power the amp may provide. Speaker impedance is measured in Ohms. Typically speakers have an impedance between 4 and 8 Ohms. Amps have a limited output voltage swing due to the fixed internal supply voltage. Hence the maximum output power is going to vary depending on the speaker impedance. The smaller the loudspeaker impedance the bigger the highest power the amplifier can output. If the highest output power is not referenced to a speaker impedance, you ought to call the producer. Typically a 4-Ohm speaker is used as a reference.
