DIGITAL ECHO

Nice circuit!!! you have to try this one. It can produce echo effect very good.The circuit very simple, consists of few passive components and one piece of digital echo chip IC HT8970. You can apply this circuit with pre amp mic or to make 3D effect of your sound system.It can be optimalized the echo effect by paralelling the input and output with the same circuit You can build two or four digital echo and paralelling the input to other input and output to other output, you can get sound very nice, if you combine with pre amp mic,the sound impressing like in the cave. If you want to combine with audio system, you can use this circuit to make 3D effect (suround)/ rear speaker pre amp.Sing jelas, regone murah hasile wah!!!!
