This is graphic equalizer circuit with PCB on 5 channel and 10 channel using LA3600. Cut frequencies of 50Hz, 200HZ,800Hz,3.2kHz10kHz. Supply voltage +12V. [...]
Do you love music? Imagine we can build power amplifiers system. Sound good, doesn’t it? Here are many circuits. For example, about Audio amplifiers, bridge amplifier, Using transistor or IC or MOSFET, Mixer, Graphic Equalizer, Preamplifiers. And, Sound generators, tone controls, Melodies, Sirens, Animal sound, effect voices. Even, Burglar alarm, and more. I cannot explain to you all. But sure I do not like to see you miss them.
These circuits are Simple Metronome circuit model to be simple. It use the transistor be important equipment by very the circuit is the character Astable Multi vibrator. For produce something…
This is simple Warble tone generator circuit , use scr as main of oscillator and signal will be boost, then feedback to SCR again. Output is 32 ohms speaker [....]
