Echo Audio Circuit

Be seen from the circuit is quite simple consists of the main equipment are 4 transistor and 5 ics only.

Echo audio circuit. Echo effect is an electronic circuit that is used to delay sound or make an echo in an audio circuit. The working of this circuit. Digital echo processor pt2399 to repro echo digital audio system of repro vco delay time system that can be arranged. By using a digital echo circuit ic designed especially for the heart to work.

This is the schematic diagram of echo chamber circuit which will convert the input sound to have echo sound just like if you talking in the cave. 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 circuit is designed as a stereo system to make it easy and easy to use applications with your amplifier followed circuit below. Digital echo processor pt2399 has a very low audio distortion of thd 0 5 and very low noise as well no 90dbv so that the digital echo processor pt2399 is capable of providing good audio quality.

I believe what they mean by surround is reverb which is actually sort of achievable more on this later in the mods section if you set your circuit up right. Pt2399 echo application circuit the second schematic princeton has on their datasheet is the pt2399 surround delay application circuit.
