Echo Audio Circuit

Digital echo processor pt2399 to repro echo digital audio system of repro vco delay time system that can be arranged.

Echo audio circuit.

By using a digital echo circuit ic designed especially for the heart to work. Be seen from the circuit is quite simple consists of the main equipment are 4 transistor and 5 ics only. This echo circuit using ic 4558d for additional amplifier and ic pt2399 as a based component. 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.

The working of this circuit. This echo chamber circuit can be applied on any source of audio signal like microphone mp3 player radio etc. 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. Pt2399 echo application circuit the second schematic princeton has on their datasheet is the pt2399 surround delay application circuit.
