In Great Britain, "power capacity" is defined as being that level of power at which waveform clipping begins to develop, while "maximum output power" is defined as "the maximum measured output power(as opposed to "rated output power" :"the power that the manufacturer claims") that the amplifier can deliver continuously to a stated load resistance at a frequency of 1000 Hz without exceeding a specified value of harmonic distortion"(cf. EAAUD, 1972, p. 36, and BSI-3860 : 1965, p. 6). Maximum power output "is commonly taken as the power yield prior to the onset of waveform clipping or when the THD(=total harmonic distortion) is at a specified value".(cf.

Class-A operation. Class-A amplifier operation is characterized by a conduction period of the output current(collector or drain) of 360°. That is, the operating point is chosen to have a constant voltage and current. In effect, the amplifier power is on all the time. This is referred to as linear operation. By operating in the linear region of the transistor's characteristics, the amplified signal suffers minimum distortion. This comes at a price of inefficiency in the amplifier. The theoretical maximum possible efficiency of a class-A amplifier is 50%, but due to linearity requirements of the applications, the efficiency may be no more that 25%.  4, record 7, English, - class%2DA%20operation

Bridgeable Amplifiers. Amplifier bridging is simply using 2 channels of an amplifier to drive a common load. For 2 channel amplifiers, one left signal and one right signal is used to drive a mono speaker load. Keep in mind that "mono" and "bridging" are not necessarily the same. Mono means that there's only one output signal. There could be more than one speaker but each speaker will have the same output. Bridging means that you are using more than one source of power to drive a load(speaker). The sources of power are one each output from either channel of the amplifier.  1, record 10, English, - bridgeable%20amplifier
