One type of regulator of tone / tone controls are the Audio Graphic Equalizer. Audio Graphic Equalizer have 2 kinds in my opinion. Namely Audio Graphic Equalizer Bar and the type of parametric type is often called parametric equalizer. Audio Graphic Equalizer In the article this is the type of bar with 5 channels using IC LA3600. IC LA3600 is a single chip "Audio Graphic Equalizer 5 channel" that is designed specifically for the equalizer five channels. Because IC LA3600 is a special design of the equalizer circuit to make this a simple equalizer. Figure series of Audio Graphic Equalizer 5 channels with IC LA3600 as follows. Equalizer Schematic Audio Graphic Equalizer circuit with IC LA3600 above can control the audio frequencies from 108 Hz to 10.8 KHz. Audio frequency which is controlled by this equalizer was 108 HZ, 343 Hz, 1.08 KHz, 3.43 KHz and 10.8 KHz. The frequency of that frequency is set based on the value of 2 pieces of capacitors in each chanelnya. So for instance...

3 Band Tone Control circuit uses an op-amp as an amplifier end. Tone Control circuit is a regulator of tone bass, midrange and treble or 3 band called because it can set the three tones. Filter circuit is applied to the series of "Tone Control 3 band" This type baxandal like the title of this article.  Results filtering regulator tone or tone control baxandal type is good, because there is no signal level is wasted directly into the ground. Range frequency tones generated from Tone Control 3 band was determined by the configuration of the R and C of the filter section baxandal. As an amplifier on Tone Control The set of three band use traditional IC LF351 has slewrate high and high input impedance. For more details, series 3 Band Tone Control as follows. Figure Series 3 Band Tone Control 3 Band Tone Control circuit above using LF351 Op-Amp is used to strengthen the signal after filtering by the filter process baxandal. Level tone Bass, Midrange and Treble settings are determi...
