AV amplifier design focus cares more about performance dialogue clarity and audio-visual environment dynamic "bursting" effect, restore or analog aloud painting-one of the sound field positioning, manufacturing a variety of sound field atmosphere. This requires not only the AV amplifier frequency range as far as possible a broad, low distortion and high signal-to-noise ratio, the transient characteristics of sound quality, beautiful tone sounds, etc., but also pay more attention to the sound pressure level: the in low distortion premise, to ensure sufficiently large output power. The units of the power amplifier output power in watts (W), measurement method because the manufacturers are not the same, so there are a number of names different names. Rated output power, maximum output power of music output power, peak music power output. The rated power of the main channel of high-end AV amplifier front to meet the requirements of the cinema 107dB sound pressure level is generally more than 80W. However, some imported AV amplifier ,5-7 channels, more than 100 per channel marked W total power of thousands of W, the power transformer is so great, I really do not know to figure out what power standards, Japanese AV The most obvious, with a total of 6 European bluffing truly figure out the chronological 100W at 8 ohms. Used the AV amplifier people know a large dynamic often seem Jiaoruan the. AV amplifier, it is recommended to purchase the best choice for a mid-range or more, otherwise just like chicken ribs. In the general case, the power amplifier is the bigger the better. But the main role of the amplifier is used to drive the speakers, so it decided on the amplifier and speakers must be matched. Many aspects involved in the configuration of the amplifier and speakers, amplifier grades, the choice of the type of power tube and low sensitivity speakers should be configured to what kind of amplifier, it is difficult to find a unified standard. And it is worth noting that the general enthusiast amplifier selected must be decided by the Speaker, the concept of "power reserve" should not have to configure the amplifier. The standard configuration of the amplifier and speaker power: under certain impedance conditions, should be greater than the speaker power amplifier power, but not too big. In the general application spaces amplifier without distortion rate should be about 1.2-1.5 times the speakers rated power; occasions in large dynamic should be about 1.5-2 times.
