Discrete, single grouping of audio information played through a sound system resulting in a steady flow of sound from one single source; for example a stereo system with two speakers has two channels, one left channel and one right channel. The channel is simply a single sound path. hink of a city water supply with five pipes feeding water into the city. Each pipe carries water just like an audio system’s channel carries sound. The five pipes are all discrete but they all carry similar water for a similar purpose working together to feed the city with water. Audio channels operate in a similar fashion all independent of one another but carrying similar information (sound) to feed the listener with a complete sound field. n audio system may have multiple channels or information routes. An amplifier may have one channel (mono), two channels (stereo), three channels, four channels, five channels or more (some amplifiers have up to 12 channels). n its most basic form, a channel is simply a path for information. In audio the channel is a path for audio information. A digital home theater system may have up to six channels (left front, center front, right front, right rear, left rear, and subwoofer channels). Television channels are frequency bands that carry information through the airwaves to the television tuner.
