3 MIC + 1AUX Input card 

सर मैं आपका चैनल सब्सक्राइब कर रहा हूँ रात के 1.35 मिनट पर आप के सभी वीडियो मस्त है जो कि आप सरलता से सीखाते है तो समझने मे भी आसानी से समझ जाता हु और ऐसे ही वीडियो लाते रहे सर मैं आपका बहुत बड़ा प्रशंसक हूं सर आप को दिल से प्रणाम 🙏 🙏 🙏

आपने बडा ही सरल व उपयोगी माइक प्री एम्पलीफायर /मिक्सर का सर्किट प्रस्तुत किया है । धन्यवाद 👍👌🙏 मेरा एक सुझाव है, अगर हम फायनल आउटपुट Op-Amp में 22 K ohm फिक्स रजिस्टर के स्थान पर 100K Lin. Pot. (उसके दो पिन शॉर्ट करके) लगा दें, तो मिक्सर का फायनल गेन अधिक बारीकी से एडजेस्ट किया जा सकेगा। कृपया इस पर प्रकाश डालें।

आपने बहुत ही अच्छे तरीके से इस सर्किट की कार्यप्रणाली समझाई, आभार। मैं कई दिनों से ऐसे ही किसी सर्किट की तलाश कर रहा था, ताकि उसे 4440 एम्प्लीफायर से जोड़ कर अपनी आध्यात्मिक संस्था के कार्यक्रम में 25-30 सदस्यों की उपस्थिति में उपयोग कर सकूं। आपका पुनः हार्दिक धन्यवाद 🙏🙏🙏

सर आपने जो जो सर्किट बताया है बहुत अच्छी तरह से समझाया है मैं आपके सभी वीडियो देखता हूं मुझे काफी लाभ हुआ बहुत बहुत धन्यवाद सर मैं लखनऊ उत्तर प्रदेश

Sar ji aapka Samjhane Ka Tarika bahut hi Achcha Laga Dil Se dhanyvad

Bahut hi achha PRE amplifier bahut bahut dhanyawad aap ka theks

Kya explaination hai ,,,. 😊😊 Ye dekhne ke baad easily bana sakte hai

कुछ भी कहो भाई तुम्हारा शिखानेका तरिका लाजवाब है , बहोत अच्छी तरह समझाते हो | हम तो फ़िदा हो गए | ऑडिओ सेक्शन से अलग सेक्शन होगा तो ओर मजा आएगा |

Well explained bro, thank you very much. I have seen some other videos also for audio amplifiers but this is very nicely explained. Also in this video the voice is clear. For testing the assembled circuit you have used a power amplifier board, which i would like to know in detail.

Fantastic explanation wonderful circuit I liked it 👌👌

Circuit bhout acha laga or basics bhi clear hue. Thank u sir

Aap ke samjhane ka tarika bahut bejod achha hai.

Bahut bdiya sir. Bahut hi useful video hai. Keep it up. Aisehi useful , interesting aur informative videos laate rahiyega 🙂👌👍

Excellent boss.Love from Bangladesh

nice veer ji super bhot hi vadia

Simple and easy best sir, really I fan of you sir

Bahut hi kam ki circuit he very nice and very good work

Very good circuit,nice and clean voice out,thanks sir

Well explained...nice diagram sir

Aap jaise hindustani ki desh ko sakt jarurat he sir

Very good bahi sahab samjhane ke liye

Good job iam in kanyakumari

Nice amplifier brother

Very nice explanations of mic ckts board. Thanks

Thanks for your sharing valuable circuitry and PCB layout design. I will surely make it and shall inform on the development. I request you to kindly give some inputs on PT2399 based mic echo/delay circuit diagram and pcb silk print on PDF. Thank you once again for your lucidly explained on Amplifier circuits and moreover your soft voice which is very user friendly. Please share your email to me or whatsapp. Keep it up Sir. Regards Shamim

Circuit ki upor best video, aisa hi samjhate rahia, nomoste

khup chhan mahiti dili sir.......thank u...

Good tiching karte hai 👌👍👌👌👍👍👌

🙏🙏 इस वीडियो के लिए बहुत बहुत धन्यवाद सर..

Thanku sir Mene bord bnaya LM 324 se 1 input to 4 output working 👍

Easy to understand... Good information to use lm324 ic

Mujhe yaad hai chhuti pe jaane se pahle aapne kaha tha ki ye video aayega. Finally lockdown me aaya.

Sir aap ka video me kuch nakuch Neya milta ha thanku sir

Sir total mic ka output single channel hoga but mp3 module stereo output deta hai aur amplifier me bhi stereo input hota hai to connection kaise karna hai ki amplifier output me mic ka sound dono channel pe aaye + song ka output stereo me dono channel pe aaye?

सर सर्किट तो ईज़ी नहीं था लेकिन आप ने सिंगल सिंगल माइक के इनपुट और आउटपुट ड्रॉ करके और फिर उसमे फीड बैक को एड करके जिस तरह से एक्सप्लेन किया है इसिसे सर्किट समझने में आसानी हुई है अगर आप पूरा का पूरा सर्किट एक बार में ही ड्रॉ करके समझाते तो शायद ये इतना आसान नहीं लगता धन्यवाद!!

Sir, one doubt...Can I connect aux to one microphone socket so that I could get mic and aux together working...Means I could get a karoake system??? Please reply.

Bahut achha sajaya apne, bilkul clear concept apne diya, lekin apse ek request hai tik isi tara garpe banane ke liye ek echo with reverb ka circuit banayenge to mere liye bahut suvista hoga, thanks

Very good ji

Good work, easy to understand and use. Low cost circuit.

Super ji circuit diagram good working 👍👍👍🙏🙏🙏🙏🙏🙏

Thanks for video Next Ab hamare pas input to bahut ho gaye . BUT hamare pas output mono hi hain aur hum aabhi sab log amplifier stereo me banate hain . To mono se stereo ke liye kya kare..........?

Too good sir achha tarah se samjaye

Very useful circuit board . Thnx sir .

नाइस वीडियो सर

Helpful .. Easy to understand. Im from kerala.. I dont know hindi.. But im understand.. Thanks.. Im Subscribed ur channel.. 👍

Basic op-amp circuit running on single power supply is nicely explained in the video. Wonder why there is no ready made PCB / module available for this essential audio mixer application. If you have made this circuit into a PCB, please share the gerber file.

Sir ji kya kamal ka mic kit banaya h

Sir very best, thanks

Make a low pass filter for subwoofer with gain control, frequency control etc....Also explain the effect of capacitors of different values in it to achieve different cutoff frequencies

Sir thanks for good education for us ...Dual supply ka ek mixer circuit banao...Please..

👍very good sir. Iam from kasaragod kerala

Nice video and explanation. I have been looking for similar circuit ready but can't find one. I have a microphone array of 4 mics in a car mirror and there are 6 wires coming out from it. I am planning to combine this into one and then input it to the android car stereo. Do you think I can use this. Or is this available readily. Any idea?

Very good sir

#Best on RU-vid Keep it up.

Nice video bro

Very nice video thankyou

Sir apne bahut hi achha samjaya muje song me echo aye aisa amplifier banana hai aisa koy board banaye Jo audio board me echo aye

Sirji. Are the capacitor mentioned are electrolyte or some other type of capacitor. I want 1 mic connection to sing and aux connection for output sound of music from mobile.(KARAOKE). What modifications required.

Sir bahut accha laga video sir 250 watt amplifir mein out put transistor ke dono compart barabar kyon nahin nahi garm ho raha hai pleas sir batayein

Class h ke bareme video dalo sir very good sir

Sir isi me echo bhi add hota with delay aur reverb toh maaza aur aata . Wase koi baat nahi wo humlog add kar lenge.

Hi sir how to by pass low filter from lm324n ic us mese kya nikal lenese vo by paas ho jayega I have triple ic 4440 broad muje usaki bass pasan nahi. Please help

Well,in ur circuits u generally give the dc.voltage , actually give them a c.supply with out filteration. Just a formula .

Nice sr g

Agar Mic se stereo output banake stereo amplifier ke dono channels mein dena ho aur sath hi audio player ke bhi dono channel uske sath mix karke dena ho jisse dono hi speaker mein Mic aur Aux ka sound aaye toh kaise connection banaye ?

इसका जस्ट उल्टा एक inचार outputकैसे होगा।अगर हमे एक मेमोरी से चार एम्पीलीफायर बजाना है ।

Sir plz aap ek video echo ki complete pcb pr banaye. Maine electro india youtube channel se ek echo pcb tyar ki thi but mujhe pcb ke sare components nhi mile jisse pcb puri nhi bani

Super se uppar

sir very nice setup for mic....apki awaz bahut achi hai....sir 1 se zyada opamp ic hone pe jo half voltage ka setup bana usme kya. change ayenge?

Thank you so much sir ji ,.

Sur, nicely explained I have this same amplifier, can I use only the two speakers output and leave the bass speaker without connecting? Like a stereo?

I have 4 ohm 50 watt 8 inch speaker with 4 ohm speaker what amplifier is best for me for very good bass. I don't want subwoofer. 2sc5200 or tda7294 or lm3886 or class d . Please reply your suggestion.

Very nice SIR Ji

Bohut badhiya

Very well described. Thank you sir

very nice,thanks

Nice video sir 500watt amplifier ke ley 1 bord bnado Jo 5 mic in ho or 2 eico mic ho 12-0-12 send opret ho please sir

Excellent video sir. Thank you.

Hatur nuhun kang

Duel supply mein yea circuit ka power supply kesa connect hoga.. aur kitna hoga sr....

Sir board me feedback rasistor ka value jyada karke gain badhane se amplifier ko koi nuksan hota he???? Ya normaly hi chalta he???

Very good information sir ji thanks

Sir aap ka vidio bahut achha laga magar aapka dayagram or aap Jo taiyar hua board meeting batate ho 2 me rezister or comonut me kyu alagsa he please batana sir.

Excellent video

Dear bro, You have a good command over your subject. I'm a hobbyist & want to know if we can add certain amount of echo/reverb to these mics by anyways?

Dear sir.is circuit main gain control krny k leay volume kis jga lgaen ?

Sir 4 and 11 pin se pawor Dena he nahi us short jumping wear se powor dena he. Replay dijiye sir
