Investigating several of the technical specs of recent stereo amplifiers, one cannot help but be at a loss in attempting to evaluate different types and technical jargon, like "t-amp", "THD" et cetera. In this expose, I am going to have a closer look at one of the most fundamental of these terms: "amplifier output power". This term is also known as "wattage".
If you are exploring to acquire an audio amp to set up your home speakers, you will frequently be confronted with a number of bizarre terms describing its performance. However how do these numbers relate to how the power amplifier sounds and how are these to be interpreted? Next I will give various details about "amplifier output power". This term is often misunderstood. It is significant to look fairly closely at how the producer shows this parameter. The output wattage of the audio amplifiers is shown as "wattage". This describes how loud your amplifier may drive your loudspeakers. If you have a small room then you don't require much more than several watts. If you wish to install loudspeakers outdoors or in a live concert then you will require several hundred watts of power. Please note that numerous amps will start distorting the music once the audio reaches higher wattage. If you want to enjoy low-distortion audio then you might want to pick an amp that will offer you higher wattage than you will really require.
The output wattage of the audio amplifiers is given as "wattage". This shows how loud your amplifier can drive your speakers. If you own a small room then you don't need much more than several watts. If you wish to set up loudspeakers outdoors or in a live concert then you will need several hundred watts of power. For best music quality, you may wish to choose an amplifier which offers bigger power than you need as many amplifiers will exhibit growing distortion once the music power increases.
Output power is either given as "Watts peak" which means the amp may produce short bursts of this level of power or "Watts rms" which shows how much power the amplifier may offer for a longer period of time. In the past, vendors have usually favored displaying the "peak power". This figure is bigger than the average or "rms" power. However, "peak power" can often be misleading as there is no norm stating the amount of time that the amplifier has to be able to output this level of output power. Still, even as the rms specification will tell you more about the amplifier's true performance, be sure however that the amp has a peak power rating which is substantially higher than the rms rating. This is because very likely you will be utilizing the amp to amplify music or voice. Music and voice signals inherently always change in terms of their power, i.e. the power envelope of the signal is going to fluctuate over time. This is since at specific points in time the signal is going to show peaks of power that by far exceed the average output power of the signal.
Usually the impedance of the loudspeakers which you connect to the amplifier will determine how much power the amp can output. Speaker impedance is measured in Ohms. Generally speakers have an impedance between 4 and 8 Ohms. Amps have a restricted output voltage swing because of the fixed internal supply voltage. Hence the largest output power will differ depending on the speaker impedance. The lower the loudspeaker impedance the bigger the highest power the amplifier may deliver. If the maximum power is not referenced to a speaker impedance, you should contact the producer. Typically a 4-Ohm speaker is utilized as a reference.
