1. How to choose a power supply?
The power supply with the board is very important. The ripple of the selected power supply must be small. A power supply with a large ripple will cause the bottom noise of the power amplifier board to become larger and there will be current noise. The higher the voltage, the greater the current, and the more adequate the output power. The power supply is 12V1A and can be equipped with 34-inch speakers. If it is above 19V 5A, there is no problem with 8-10 inches, and the power supply must be highly regarded. If the voltage is too low, the amplified sound will easily cause sound distortion. If the current is too low, the speaker will pull down the voltage, which will result in abnormal operation or poor sound quality.
It is recommended to use a power supply of 18V19V24V with a current above 5A. If you only have 9V12V or 1A 2A power supply, it can be used but the power is low. When the volume is selected close to the maximum, it may be distorted and affect the sound quality.
2. How to choose a speaker?
Regarding speaker types: commonly used speakers are generally 4-8 ohms, which can be used. The left and right channel speakers need to be connected to full-range speakers or mid- to high-frequency speakers, and the power is between 20W-100W. The subwoofer speaker cannot be connected to an ordinary speaker, and a speaker with a subwoofer speaker must be connected with a power between 20-100. The dive frequency of the subwoofer speaker must be at least 50 Hz.
If your speaker has a low power, such as between 20W-50W, it can be used. You need a lower power supply voltage to prevent the speaker from burning after amplifying the sound. For example, choose a power supply below 15V.
If you are a 50W-100W speaker, don't worry about the problem of speaker burnout. You can choose a 12-24V power supply. The higher the selected voltage, the greater the sound or power that can be output. The speaker power should not exceed 100W, otherwise it will affect the sound quality. - Věda a technologie
Apki jankariya bhut achchee hoti aour dil ko chune vali hoti he sabse badi baat aap se bharpur gyan milta he🤔🤔🤔
Bhut hi acha laga 🙏🎉
Next video ka intzaar rahega
❤️❤️Thank you...You are doing very informative videos. I am also trying to build a amplifier. Your videos helps to cleat my doubts... Could you do a special video of active crossover circuit making which includes main volume control, high , mid & low pass filtering. Can you explain how it will calculate. Can you explain regarding active crossover frequency seperation comparison between passive cross over graphically. Also I have doubts regarding amplifier bandwidth... Could you explain all these questions If possible.. Thank you...
Nice work and good amplifier, decent sound.
Sir ji great 👍 akhir hamare liye aapne ye video laya
धन्यवाद भाई साहब मैं धुलिया महाराष्ट्र से

India me Jo bana te hain colourful bana dete hain ye dekhne me hi solid lag raha hai
Excellent performance bro I bought one year before
Good and informative video. Thanks.
WOW Very good information vedio👍👌👍👌
Passive crossover के coil बनाने के व्हिडिओ के लिये thanks in advance,🙏
Main problem of this amplifier is degrading signal in china "processor". Line in signal don't pass directly to pre amp, but first pass bt processor... The sound with processor bypass is much better. Also @Yagnesh Patel indentify that this version didn't have EMI filter on exit and it is should be fixed at least by ferrite rings. Or buy same amplifier with filter (ZK-TB21).
🎉very useful ... online amplifiers❤
Informative video sir ❤,
Excellent audio quality 👍
Passive crossover wala video ke liye wait jaari hai 😁
Nice Amplifire hai sir.....price ke compare me baht achha hai...👌👌👌

3 war passive crossover bana kar batayen..
बोहोत ही अच्छा विडियो बनाते है सिर आप
क्या मैं इस बोर्ड में कार के ओवल स्पीकर ओर सब्बुफर घर मे चला सकता हु
This amp don't have channel isolation while using aux. It works as mono channel while using the aux. so basically it is 1.1 amp while using aux (zk mt21 model)
Use 3 ring 3.5 mm cable at both ends.
@@WhatIThinkbluetooth se stereo aur Aux pin se mono sound ka issue hai kya ?? Please reply
👍👍👍
To stop interference totally i changed my old woofer with 20 to 200 Hz woofer. Now no mid is entering in woofer and sound is perfectly clean. Thanks a lot Sudhir jee.I am waiting for your video on speaker column with 3 way cross-over plate.😊
Thanks Sir.
Kitne inch ka woofer lagta hein
Sir Sound is clear ok nice
Love you bhai ❤️
Does it have short circuit protection on the speaker output? I'm just curious because i accidentally shorted the speaker output of this amplifier while it sounds😢
One video on passive bass radiators plz ☺️☺️☺️
Kya parice hai bhai ji iska 😍🤩😘

Can you please make a video on how to get pre amp out from this board(L+R). I want to use this 2.1 as bluetooth input and add 2+1 bigger amplifier (300W per channel) to make 5.1...... or alternatively If I use separate pre amp how to use this board as amp bypassing built in preamp
superb boards ❤️👍👍
Please sir make video on designing active crossover.
Sir you said that blue board of tpa3116d2 is best i have purchased both blue and red but on red board my subwoofer perform very good but on blue board its not performing up to the mark even they both have same chip...please help me how i can get good result on blue board
Sir please tell me which board is best this one or 3116d2?
Awsmm sound qlty...
I am a subscriber and regular viewer you have clearly give review of each boards its advantages and disadvantages then what are modification to do lot of things are explained in previous videos that was the main reason I keep on watching this channel. But this video made much disappointing as it was like a regular video what others are doing no clarity about the details.

Sir TDA8932 ki upar video banaoo please🙏
Or Qualcomm bluetooth chipset kia hai
बहोत बढ़िया साउंड आउटपुट है इसकी 👍। क्या इसमें ओवर हिट की प्रोब्लम ज्यादा है ? और क्या इसको हम नॉर्मल बैटरी से कितने amp पे प्ले कर सकते हैं ?
Aawaj sun raha hoon dikh nahi raha hai🤪👌
Sir please reply i am confused i have purchased wuzhi 2.1 tpa 3116d2 100watt+2*50watt amplifier on its cover there is mentioned that it gives 100watt at 8ohm for subwoofer and 50watt for 4ohm but as far as i know if the resistance decrease the output must increase, that is why i want your experienced opinion please tell me which subwoofer and speaker i should buy 4ohm or 8ohm?
buy 8 ohms only
sir 380rms 4 ohm subwoofer ko zyada se zyada kitni rms ki power deni chahiye?
wao its halpfull
hi sir .... ye board me 12v 10amp ka adeptor laga sakte he
Sir TDA7294 Stereo board ko mono (Bridge) kaise kartey ha ek video ho jata toh bahut hi accha hota.
Nice video 👍
I USED THIS AMP.. IT VERY LOUD AND CLEAR BUT I FELT LACK OF DEEP BASS IN SPEAKERS ONLY.. THE SUBWOOFER WAS GREAT THOUGH BUT BASS FROM SPEAKERS WAS NOT ENOUGH AND TO GET THAT THUMPING AND FEEL OF BASS WE NEED TO SET VOL TO MAX WHUICH BECOMES MUCH LOUD.. SO NO BASS AT LOW VOL... I HAVE NO IDEAD ABOUT HE 3116
Dc to DC boost converter per video chahiye , jisse hum amplifire ko chala sake
Sir, can i run this with 18-0-18 5amp?
Clarification: when I converted it from AC to DC its giving me 0-29 v DC output. Though it will reduce to some extent after giving the load, I am afraid to connect this with WuziAudio 2.1. Please give me your inputs on this sir. This will help me complete my project. Your response is greatly appreciated.
No... Don't give more than 24 volt. Give 21 for safer operation.
Thank you for the reply sir …!
Hello sir... Can i use this amplifier in micca b42x speakers??

4. Sir which is good single opamp or double or tripple?? 5. Which type o speakers ;sub and twitter needed?? 5.And their watt and which quality??. Plz sir answer this questions. I have arranged some money and i am 17years old. Plz tell me how can i connect with audio. how to shine in life. Sir plz answer this question plz sir plz. 🇧🇩🇧🇩🇧🇩🇧🇩 LOVE FROM BANGLADESH.
Sir plz answer this questions plz sir plz
Sir plz answer that questions
For outdoor 2.1 system minimum 500 watt subwoofer is required with 200+200 watt speakers. You have to use transistor amplifier for that. Also you can use class D for subwoofer and Class AB Transistor amp for Left Right Channel. But the enclosure design is most important here along with good quality speakers otherwise there will be no enough SPL for outdoor. Local speakers can be used but it should be with big voice coil and magnet. For opamps,..it depends upon your use. all are good. However try to make each circuit separate for left and right channel for good performance. Do not use same op amp for stereo channel for good separation.
@@WhatIThink love forever sir 🇧🇩🇧🇩🇧🇩
Dc to DC step up conwatar circut banavo please
Sir please suggest good quality sound output 2.1 amplifier board for home use.
sir please passive crossover ka video bnayeye
Sir do have question
I had purchased from ink ocean
I have smps for 24 volt but the ampere is just 3 ampere
Will it be fully efficient in 3 ampere for this product Wuzhi ZK-MT21
I Did had speaker setup in wooden box for 8 inch subwoofer
2 oval 6 inch car speaker 4 ohms
3 amp is not sufficient. Though it will work good at lower volumes. You should get at least 8 amp. Best power supply for this board is 24 volt 10.amp.
@@WhatIThink lot's of respect and Thankful for sparing precious time along with professional and CZcams career
Bro, kya 10 inch ka basstube subwoofer zordar bajega ispe?
Which ic is used in this board TPA3116 ?

Sir 10 pair 2sc5200 & 2sc1943 lagane hai 1 amplifier me to sir usse 2ohm pe chalne ke liye usme maximum kitne volt & kitne Ampere Ka transformer lga sakte hai
Bus ye bata dijie kya iske subboffer ko use karne ke liye speakers ya suboofer ko alag se power supply dena hota hai kya??
Sir there is a frequency controller in it. Does it mean it has a crossover, atleast on one driver? If so, does it mean it is partially a three way board?
No sir. It has variable low pass filter on subwoofer channel. You can use any subwoofer from 20 to 200hz frequency response.
