Matt circuit

Effect Echo is an electronic circuit that is used to delay sound or make an echo in an audio circuit . Using a circuit of echo is easy enough , we just set on the volume, and gain and trimpot near is rate of 20 K ohm to adjust how the desired echoes. This echo circuit using ic 4558D for additional amplifier and ic PT2399 as a major component that serves to echo , or repeat the sound output on the audio system.

Then turn down the volume, and slowly raised, setting echo effect on the trimpot 20K. If not check back for the damaged to the circuit.

This tremolo effect circuit uses the XR2206 and the TCA730 IC which is designed as an electronic balance and volume regulator with frequency correction. The circuit is use full for stereo channels and it also has the ability to simulate the Lesley effect aka rotating loudspeaker effect. How does the tremolo effect circuit works Balance and volume settings are done with a linear potentiometer for both channels. If this potentiometer is replaced with an AC voltage source, a periodic modulation of the input signal can be achieved. This AC voltage source comes from the function generator IC XR2206. This IC generates square, triangle and sine wave signals but for this project we use only the sine wave. IC  Tremolo Effect Circuit Diagram   The modulation voltage can be varied with P1 from 1 Hz up to 25 Hz. Resistor R3 sets the operation level of the sine wave generator. R5 and R6 set the DC voltage and the sine wave amplitude at the output. C2 is a ripple filter. The square wave ou...
