Since distances between speakers and amplifiers are much more than a few feet, compared to a home entertainment system, the technics are different. This is not a high fidelity system so it does not sound as good as a home entertainment system and it is not a sterio sound system. Normally there is one powerful amplifier and numerous speakers arranged in different areas or zones and there is one volume control for each group of speakers.

Meeting rooms use this system to make the speaker's voice be audible to everyone in the room.
