Advice For Spotting The Right Audio Amplifier

I will have a look at some audio amplifiers and clarify some vital language to help you select the best amp for your loudspeakers

Audio amps come in all different shapes and sizes. They employ different technologies and have a lot of technical specs. This makes it tricky to decide which type to select. You don’t have to be a specialist. Just follow some simple guidelines and you ought to be satisfied with your amp. The most evident parameter is the size of the amplifier. There are types that are as big as half your living room while several of the newest mini amplifier (just click the following document) models are as small as a bar of soap. Numerous models will be the size of a ordinary audio rack so that you can simply stack it on top of your audio equipment.

Nearly all of recent audio amplifiers are based on solid-state technology whereas a small portion is based on tube technology which has been popular over a decade ago. Regrettably, tube amplifiers have fairly high audio distortion which describes how much the audio signal is degraded by the amp.

Tube amps will have audio distortion of up to 10%. Solid state amps will have lower audio distortion depending on the amplifier technology that is utilized. Some of the most accepted technologies in the past have been "Class-A" and "Class-AB" technologies. These technologies use different arrangements to amplify the sound. Amps based on any of these technologies are also referred to as "analog amplifiers". This technology provides rather low audio distortion. Though, the power efficiency is only 10 to 30%. Power efficiency describes how much of the electrical power is utilized to amplify the audio as opposed to being wasted as heat. Amplifiers with low power efficiency will need rather big heat sinks because most of the power is radiated.

Another technology is called "Class-D". This technology offers much higher power efficiency than analog amplifiers, generally around 80 to 90%. "Class-D" amplifiers are also called "digital amplifiers". The downside is that many digital amps have higher audio distortion than analog amplifiers though some of the most recent models make use of a feedback mechanism to reduce distortion to levels of 0.05% and less. When choosing an amp, ensure that the output power is enough to drive your loudspeakers. The required power will be determined by how much power your loudspeakers can tolerate as well as the size of your space where you will be listening. There are two values for speaker power handling: peak and average power handling. The peak value shows how much power the loudspeaker can tolerate for small periods of time. The average value on the other hand describes how much power the speaker can tolerate continuously without harm. If your listening area is fairly small then you might not require to drive your speaker to its rated power handling value. You would almost certainly be ok getting an amp that can provide 20 to 50 Watts although your loudspeakers might be capable to tolerate 100 Watts of power. Low-impedance loudspeakers usually offer high sensitivity and are easier to drive to high volume than high-impedance speakers. Not all amps can drive any speaker impedance. Find out the impedance of your speaker which is given in Ohms. Then take a look at your amplifier manual to guarantee that your amp can drive this impedance.

Two additional significant 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 amp. The frequency response shows which audio frequency range the amplifier covers and should be at least 20 Hz to 20 kHz.
