What is a 3 -channel amplifier?
While a mono or single channel amplifier takes one line signal, such as the Blu-ray ™ signal, and increases its performance to control the speaker, the three-channel amplifier increases three signals at a time. The three -channel amplifier occupies the medium space between the two -channel stereo amplifier and the five or the seven -channel amplifier of the spatial sound. It brings the advantages of cost and universe that it has one component that controls more channels without driving so many channels to cause the performance to reduce.
Like any external power amplifier, the three -channel amplifier should offer a better sound than amplifiers built into the receiver. The amplifier components with three-channel power are designed to do only one thing-take small signals and enlarge is-and are usually built for this one task. To this end, they have special -purpose power supply, which can create a large amount of clean energy to drive the speakers to the high tube as possible. Their tThe amplification allow them to work with a two -channel stereo amplifier in a five -channel spatial sound system.
The most typical use of the three -channel amplifier is in the domestic cinema system that already has a receiver. By connecting the preamplifier terminals for the left, center and right front channels to the amplifier, the most important channels will gain the advantage of the external three -channel amplifier. The receiver must then control only the rear and right spatial channels. This makes the receiver easier to supply its rated power, as its power supply is not required to reproduce five audio channels. Also, because most receivers have sound quality that is lower than external power amplifiers, this setting ensures that the only channels that are processed by the receiver are channels that are Least active and important.
Three -channel amplifiers, however, are used outside the home cinema application. Some sound nAdhesion believes that independently reinforce each driver in their speakers increases sound quality. The bass control speakers, the half-frequency controller and the high-frequency controller require one three-channel amplifier that is a "tri-Amp". The sound system configured in this way requires two three -channel amplifiers to control a stereo pair of speakers. Many top -of -the -range automobile sound systems use these components' amplifiers that separate bass, medium and high -frequency drivers.
