Tone control circuit

<p>Tone control is a type of <a href="/facts/Equalization_(audio)/hHGUDhRR">equalization</a> used to make specific pitches or <a href="/facts/Frequencies/QUSbPaW8">frequencies</a> in an <a href="/facts/Audio_signal/rFSTI9IF">audio signal</a> softer or louder. It allows a listener to adjust the tone of the sound produced by an <a href="/facts/Audio_system/BMbpAWkE">audio system</a> to their liking, for example to compensate for inadequate bass response of loudspeakers or earphones, tonal qualities of the room, or hearing impairment.  A tone control circuit is an <a href="/facts/Electrical_network/zt94kTW0">electronic circuit</a> that consists of a network of <a href="/facts/Electronic_filters/ny7k6VxV">filters</a> which modify the signal before it is fed to <a href="/facts/Loudspeaker/tqEjnJ2z">speakers</a>, <a href="/facts/Headphones/hLd5e4Kv">headphones</a> or recording devices by way of an <a href="/facts/Amplifier/pnRgxncC">amplifier</a>. Tone controls are found on many sound systems: <a href="/facts/Radio/XFr909M2">radios</a>, <a href="/facts/Portable_music_player/N0pUt1kQ">portable music players</a>, <a href="/facts/Boombox/R6N3qGlt">boomboxes</a>, <a href="/facts/Public_address_system/LlLkJgNz">public address systems</a>, and <a href="/facts/Electric_guitar_amplifier/d5sDShUH">musical instrument amplifiers</a>.
