Selecting The Perfect Audio Amplifier For Your Home
Choosing the right audio amplifier can be daunting given the large number of diverse models and technologies. I will assist you understand some of the essential amplifier jargon terms. This information will assist you choose the perfect amplifier.
An audio amplifier will connect your audio source with your loudspeakers by converting the rather weak source signal into a strong enough signal to drive your loudspeakers.
Even though some audio sources have already a built-in amplifier, a separate amplifier gives you more freedom for picking the model that best complements your speakers. There are some mini amplifier types available. These types are small sufficient to conceal virtually everywhere.
Most people will take a look at amplifier wattage first when picking an amplifier. Output wattage is the level of power the amplifier is capable to deliver to the speakers. Driving low-sensitivity loudspeakers (sensitivity is shown in dB/W) calls for relatively high wattage. Moreover, driving outdoor speakers or speakers in a large room will require higher amplifier power. Don’t overdrive your speakers however because this may irreparably harm your speakers.
Yet, amplifier wattage is not everything. Good sound quality is possibly more important than raw power. A 20 to 50 Watt amp should be sufficient for most real-world applications.
Amplifier wattage is given either as rms or continuous power which shows how much power the amplifier can deliver constantly or as maximum or peak power which shows how much power the amp can output for short periods of time. You ought to choose an amplifier that has sufficient rms power, even though 10 to 30 Watts should be sufficient for most applications but has adequate headroom for peaks that happen in music signals.
On the other hand, audio quality is just as important as having enough audio power. For that reason be certain to also look at factors related to the quality of the amplifier. One of these parameters is referred to as total harmonic distortion or THD. No amplifier is completely perfect and the amplified signal will include some error components which will distort the signal to some amount. THD is either expressed in percent or dB. A smaller distortion number means a lower distortion of the audio signal by the amplifier. Audiophile-grade amps will have distortion figures of at most 0.05% whereas consumer-grade amps have distortion of up to 10%.
Another figure related to audio quality is referred to as signal-to-noise ratio and describes the amount of unwanted noise the amplifier will add to the signal. Audiophile-grade amps will have an SNR of 100 dB or higher. Consumer-grade amps will have at least 80 dB signal-to-noise ratio.
Most of modern amplifiers are so-called Class-D amplifiers which means that they have higher power efficiency than Class-A or Class-AB amplifiers and for that reason waste little power as heat. Class-A and Class-AB amplifiers require a reasonable amount of heat sinking and therefore are generally fairly large and heavy. In contrast, amplifiers based on the Class-D technology are small and lightweight. Some of today’s smallest mini amplifiers are no bigger than a deck of cards. Though, when choosing a Class-D (digital) amplifier, be sure that the amplifier has low distortion and a high signal-to-noise ratio.
