Mono
Today, mono is still used in certain applications. Basic, small screen televisions
with a single speaker use mono, as do small audio divices where sound quality is not
really a factor. Conversley, mono is used in some of the best and most expensive
hi-fi and home cinema systems. Using a series of monoblock amplifiers on the separated
stereo or multi-channel soundtrack channels, improvements can be achieved by reducing
interference that can affect integrated stereo amplifiers. It allows a 'cleaner' audio
signal to be used with less interference from other electrical components.

Mono sound is a single channel of audio. The
first sound recordings were mono and until the seventies mono was the main sound
format for television broadcasts. Movie theatres used mono sound until the roughly
same time, although many has upgraded to the new multi-channel analogue formats.
