Multi-channel amps do the work of several amplifiers combined into one unit and are a great way to expand audio into other areas of the house. These amps deliver power independently to different channels or zones and the power depends on what type of system you’re designing. For instance, a 6-channel amp could supply clean power to four in-ceiling speakers in the kitchen and two patio speakers. A 12-channel amp could supply power for stereo sound in as many as six rooms in the house. Like any amp, multi-channel amps use different types of solid-state circuitry to get the job done. Some of the most common include Class A, Class A/B, Class H and Class D which uses highly efficient digital circuitry.
