Mastering The Wattage Specification Of Class A Amplifiers

Investigating some of the technical specifications of todays audio amps, one cannot help but be at a loss in attempting to compare different products and technical jargon, like “t-amp”, “THD” and so on. Then again, it is often misunderstood. Several companies also in history have used this term in a perplexing manner in order to hide the true performance.

This describes how loud your amplifier may drive your loudspeakers. You want to select the amplifier wattage based on how big your listening environment is. For best audio quality, you might wish to go with an amp that offers higher power than you require because most mini stereo amplifiers will exhibit increasing distortion as the audio output power increases.

This number is higher than the average or “rms” power. Thus the peak power rating is nonetheless important, though not as important as the rms power specification. Having a high peak power rating will guarantee sufficient headroom for music peaks which are common in music signals. Though, be conscious of the fact that the greatest output power also is dependent upon what type of speakers you are using, specifically the impedance of the loudspeakers. Speakers frequently have impedances between 4 and 8 Ohms. Due to the limited amplifier supply voltage, the largest output power is going to be half if you connect an 8-Ohm loudspeaker of the peak power that the amp may output to a 4-Ohm loudspeaker.
