             Differentiate between mono, stereo and two-channel sound systems

Description of a mono system: All audio signals are mixed together and sent through a single audio channel. There can be multiple speakers in a mono system, even multiple speakers spaced far apart. The point is that the signal does not carry any information that reproduces or simulates the original position of the sound, such as differences in signal levels, time of arrival/phase information, etc.

Common types of mono systems include:

1/mono center speaker group

2/Mono separation speaker group system

3/ Distributed speaker system (with or without delay speakers)

Although mono, the system still delivers full frequency response, high fidelity, and is effective at amplifying speech and music. The great advantage of mono is that everyone hears the same signal, and, in a sensible system design, all listeners hear essentially the same system SPL. This makes mono systems ideal for speech reinforcement, as they are relatively easy to produce with excellent speech intelligibility.
