Very good job u done,12volt DC par theek kaam krta hy Laikin mini circuit Jo ap ny use kiea hy Usk7 sound nai aya,mujhy 3.7v battery k sath operate honey wala bta dijiey,,aur 4440 ic k sath humming aur shor bhi krta hy
Does this really need a preamp or not? I just put this together on a dot board using a heckuva lot of circuit wires some good while ago (more than months!) and yesterday, I just hopped in to my desk to re-model it from scratch for a PCB. During the first phase, I tested this with a line input rather than a mic, although the output is bass-light, I was really impressed! I had a blast playing with the controls, the delay time knob was the funnest, also the output knob was also magnificent! At full blast, the echo out surpasses the input as a positive feedback as it should [I slapped in some pair of resistors to mix the dry signal (Actual source) with the wet (delayed) signal] and in its minimum position, it seemingly introduces a negative feedback that results in an endless (not earraping) tunnel-reverb-like effect too! However, with my homemade 3xC945 Dynamic preamp, I got a lot of noise. Hopefully, I've added a large heatsink onto the 7805 chip and with some sort of a highly-experimental grounding technique (either my body or some clothing iron tapped on the floor) the noise got reduced to some extent.
Yes it needs a pre-amp as the output signal is un-amplified and doesn't pass through an actual amplification stage. I think the whole Circuit here has no actual amplification but just alters the incoming signal on the effect and mix stage (dry or wet) but without any amplification. Try maybe 2 of these N5532 OpAmps both at the input stage and the output stage to get a louder signal.
@@KRAFTWERK2K6 yeah. That circuit he made just outputs the wet signal. So I'm starting with a delayed version of what I speak. I got around that using a resistor divider and connecting the dry signal again to the output leads eliminating the feedback. My mic preamp (uses 3 c945 transistors) is apparently too loud in addition.
Hi, do you have any circuit diagrams that provide repeat sounds like 2 sec 5 sec 10 seconds? No delay or echo. In Gujrat sound operators are used for Gujarati dayro.
Sir Mujhe 8. 2 nanofared capasitor nehi mil rahi hain to uske jaga keya or capacitor use kiya ja sakta hain??? Or sir mujhe 8. 2 nanofared capasitor mili hain but wo 1600 volt ki hain keya wo use kiya ja sakti hain???? Please sir ekbar repla de dijiye Mujhe bohot dikkat ho rahi hain... 🙏🙏🙏
Main ne ek Chinese speaker liya hai mic k saath (radio/USB/Bluetooth/mic). Masla ye hai k mic laganay par echo aatee hai jo band naheen ki ja saktee. Koi modification ho to bataen.
Sir transformerless power supply mein pf cap aur resistence ek doosre ke parallel mei hote hai .yeh kaise kaam karte hai jab isme ac ya dc input karte hai .kaise yeh output deta hai.aapne kaha hai ki yeh sirf ac par kaam karta hai.par maine dekha hai ek music sys mei 104j pf ke parallel mei laga hai.sir aapse request hai ispar vdo bana dijiye ki ispar pf cap aur resistence kya kaam karte hai.animated vdo bana dijiye.
Sir es project me kuch microseconds ka gap ho jara hai sound ampli se hoke speaker tk phuchne me esi disadvantage ko door krne k liye sound mixer ka use kia hai mene ye delay kisi b tarh door nhi hotaa normally practicals me
Bhai koi karaoke sistam me kon kon si chije lagti hai jise batri aur bijli se bhi chala sake in sab ki jankari chahiye 200 watts me mujhe sterio,blututh,1 mid,1 tutter ,12 ench 1bufar ke sath banana chahta hu bhai kirpya Puri jankari par ek vedio banao please🎉❤🎉❤
Sir today I Subscribe your channel & I love your all projects . Sir I request you for make a mic amplifier circuit. On RU-vid many circuits are available and I make it but it's not work properly and humming sound comes so it's my request for make mic 🎤 amplifier circuit 🙏
