Mono channel or mono sound is referring to a system that all audio signals are mixed together and then then go through a single audio channel. The advantage of mono channel is that everyone is hearing the same signal, and in the design of system, the sound pressure levels to all the audience are basically the same. This makes well-designed mono system very suitable for audio amplification, bringing about remarkable speech intelligibility.
