Watt Amp
Choosing The Best Audio Amplifier For Your Speakers
Looking at today’s audio amplifier products, one cannot help but be overwhelmed by the number of technologies and models. Regardless of your application, I will describe some essential amplifiers language which will be helpful when selecting the best model.
Audio amplifiers are indispensable since your audio source such as your DVD or Blu-Ray player does not provide a signal powerful adequate to drive your speakers. The amplifier will be the bridging element to your speakers. It will convert the weak source signal to a signal powerful enough to drive your speakers.
Even though some audio sources have already a built-in amplifier, a separate amplifier offers you more freedom for picking the model that best complements your speakers. Some of today’s mini amplifier models are small enough to conceal them almost everywhere.
When picking an amplifier, your initial consideration possibly is the amplifier output wattage. You will need a high wattage if you are driving loudspeakers with a low sensitivity (expressed in dB/W), for driving speakers in big rooms or for outdoor speakers. You shouldn't employ an amplifier with considerably higher output power than your speakers can handle. Overdriving your speakers may do irreparable harm to your speakers.
Still, a 20 to 50 Watt amplifier will give you more than enough power in most situations so don't be overly concerned about the rated amplifier wattage.
There are two conventions for specifying amplifier wattage. The first one specifies how much power the amplifier is capable to deliver continuously. That figure is often called rms or continuous power. The second number is titled peak or maximum power and tells how much the amp can deliver for short bursts. You ought to select an amplifier that has adequate rms power, though 10 to 30 Watts ought to be plenty for most applications but has adequate headroom for peaks that happen in music signals.
Audio quality is just as significant as having adequate audio power and therefore you ought to also look at figures such as total harmonic distortion or THD. No amplifier is totally perfect and the amplified signal will include some error components which will distort the signal to some degree. THD is either expressed in percent or dB. The level of distortion varies between amplifier models. A smaller distortion means higher audio quality. The amount of distortion will be less than 0.05% for a high-quality amplifier. Consumer type amplifiers have higher distortion figures. Typical figures are up to 10% depending on the output power.
Another figure related to audio quality is called signal-to-noise ratio and describes the amount of unwanted noise the amplifier will add to the signal. Higher-end amplifiers will achieve a signal-to-noise ratio of at least 100 dB whilst consumer grade amplifiers will normally have a signal ratio of at least 80 dB.
The majority of today’s amplifiers are based on a technology known as Class-D which offers higher power efficiency than amplifiers based an Class-A or Class-AB technologies. High efficiency means that little power is wasted as heat which can make the amplifier quite small. Some of today’s mini amplifiers are no bigger than a deck of cards. Many Class-D amplifiers, though, have higher distortion and a lower signal-to-noise ratio than Class-A or Class-AB amplifiers. Be sure to look closely at these numbers when picking a Class-D type amplifier.
