Ideas For Spotting The Ideal Audio Amplifier
If you have paid a good amount of cash on a pair of good-quality speakers, you wish to be certain that you get an audio amplifier that will deliver outstanding sound quality while meeting your budget. I will provide a few tips regarding audio amp devices to help you make the perfect purchasing decision.
It is difficult to pick the perfect audio amplifier as a consequence of the large quantity of types. All of these models have different specs. They are based on different technologies and come in all kinds of shapes and sizes. This makes it difficult to make a decision which model to choose. You don’t have to be an expert. Just follow some easy suggestions and you ought to be satisfied with your amplifier.
The most evident parameter is the size of the amp. There are types that are as large as half your living room whilst a number of of the latest mini amplifier models are as small as a bar of soap. Many amplifiers are rack sized. This enables them to be stacked on top of your other audio equipment.
The huge majority of modern audio amps are solid state amplifiers vs more traditional tube amps. Tube amps have been dominant a decade or so ago. Unfortunately, tube amps have relatively large audio distortion which describes how much the audio signal is degraded by the amp.
Harmonic distortion of tube amplifiers is often as high as 10%. Solid-state amplifiers will have less audio distortion. On the other hand, distortion will depend on the particular audio amplifier technology. Some of the most popular technologies in the past have been "Class-A" and "Class-AB" technologies. These technologies use different arrangements to amplify the audio. Amps based on any of these technologies are also called "analog amplifiers". Audio amps which are based on these technologies typically have low harmonic distortion. Also, this technology is fairly inexpensive. However, the disadvantage is that the power efficiency is merely in the order of 20% to 30%. Power efficiency refers to how much of the electrical power is actually used to amplify the signal. The left over portion is wasted as heat. An amplifier with low power efficiency will radiate most of its power as heat.
"Class-D" amplifiers, on the other hand, which are also known as "digital amplifiers" have a power efficiency of at the least 80% and are smaller and have a smaller power supply than similar analog amplifiers. The tradeoff is that digital amps frequently have higher audio distortion than analog amps. This is mostly a result of the switching distortion of the output power stage. Latest digital audio amplifiers, though, make use of a feedback mechanism and can minimize the audio distortion to below 0.05%.
Your amplifier should deliver sufficient power to drive your speakers. The amount of power will depend on the power handling rating of your loudspeakers. An additional parameter is the size of your room. Loudspeaker power handling ability is specified as peak power and average power. The peak power value refers to how much power the speaker can handle for a short period of time whilst the average power handling value describes how much power you can drive the loudspeaker at constantly without harm.
If your listening area is fairly small then you may not need to drive your speaker to its rated power handling value. You would almost certainly be ok getting an amplifier that can deliver 20 to 50 Watts although your loudspeakers might be able to tolerate 100 Watts of power. Low-impedance loudspeakers typically offer high sensitivity and are easier to drive to high volume than high-impedance loudspeakers. Check your amplifier manual to ensure that your amplifier can drive your speaker impedance.
Two other important parameters to look at when selecting an amplifier are signal-to-noise ratio and frequency response. Signal-to-noise ratio describes how much noise the amplifier will generate and should be no less than 100 dB for a high-quality amplifier. The frequency response reveals which audio frequency range the amplifier covers and should be at least 20 Hz to 20 kHz.
