This be Control signal Automatic Fader circuit , help fine decorate or control sound signal tallly or low follow want. In model the automatic convenient for the system electricity guitar , side sound of music work. By this circuit uses FET , then have tall rapidity , there is the crazy low and use IC [...]

Here is Circuit classic Wien Bridge oscillator using an Op-Amp covering a frequency range of 15 to 150kHz in four switched steps. Two conditions exist for a sinusoidal oscillator. Regenerative or positive feedback, and a closed loop gain of unity. The losses in the wien feedback circuit, are such that the open loop gain of [...]

Description: A simple mixer with 3 line inputs and 3 mic inputs using commonly available parts. Notes: The mixer circuit below has 3 line inputs and 3 mic inputs. The mic inputs are suitable for low impedance 200-1000R dynamic microphones. An ECM or condenser mic can also be used, but must have bias applied via [...]
