In recent years, a number of manufacturers in order to market demand, the combination of functions including AV amplifier, KALAOK integrated amplifier, including the so-called "integrated amplifier", which is a hodgepodge amp, everything, do anything good, East Lake Conference amplifier, power amplifier is oriented to resist the countryside. Watch your TV has no audio output function, that is, you see the back of the TV OUT or there is a semicircle there is an arrow out of a set of (2) the audio output. (It should be a red, Nanhu meeting amplifier, a white circular jack) you say is sound amplifier connection are the surround left and right, center, left audio, amplifier, and right audio in general, A class amplifier costs about twice as much power class AB amplifier or more. 2, class B power amplifier (PA B) Class B amplification works is when there is no signal input, the output transistors non-conductive, so I do not consume power. When a signal, each output tube for each half of the waveform zoom, rotate each opening and closing completed a full-wave amplification, when both output transistors work rotation will occur crossover distortion, thus forming a non-linear. Less pure class B amplifier, because the signal is very low distortion is very serious, so crossover distortion make the sound becomes rough. Class B power amplifier efficiency averaged about 75%, the heat generated lower than A class machine, Nanhu professional amplifier, allowing the use of smaller heat sink. B amplifier generally work into OCL and BTL, BTL can provide greater power, at present most of the power IC can be used two pieces BTL circuit.
