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.
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.

wuzhi audio vs tpa3116d2 2.1 best saund quality konsi? mere liye aapki rai mahatvpurn purn hai?
sir my tpa3116d2 board par ak problem horahah!! bluetooth card use karne par bass nahi ata h jiyada but aux use karne par thik atah!! and board par power denebr ne5532 ic bohat heat hota h!! kia karu ab!! ic chane karne par kia bluetooth pe bass ayega?? Help plz
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
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
Apki jankariya bhut achchee hoti aour dil ko chune vali hoti he sabse badi baat aap se bharpur gyan milta he🤔🤔🤔
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).
hi sir .... ye board me 12v 10amp ka adeptor laga sakte he

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.

@@WhatIThink I don’t thik so
@@yagneshpatel1183 @Yagnesh Patel Correct. Mine version of this amplifier have filters. I even didn't identify that it is different version if not your comment.
But, to be correct. Manufacturer offer, as an option, to use ferrite rings instead of inductions/capacitors filter. So it is possible to buy additional 6 rings for each wire... But result is unclear.

Kharab ho jayega
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.
The unit I received was not working properly or this is how it is designed as when I plugged in with a 3.5 mm jack connection the sound output received is a mono channel or you can say both the channels are overlapping, I have tested thoroughly with multiple cables and sources but the issue stays
Have you used 3 ring 3.5 cable.

@@WhatIThink Thank you sir.🙏
I feel mids are suffering with overriding bass pressure. Can we split the mid+ low into Mid band and low frequencies, if yes how?
Sir, this board has seperate bass control for both woofer and LR channel. We can adjust as per our requirement
@@WhatIThink Now I have got the idea, If I make a separation between subwoofer and Mid+high, acoustic interference pressure can be avoided or long back you described use of 2 S/W for cabinet designing, may be with some alteration Mid and Lows can be installed in single enclosure. Tweeters are, I think generally sealed from back so it may be no issue, as you already demonstrated. I saw physical separation of mid as cabinet in cabinet in a vintage enclosure of Armstrong USA stereo (50x50RMS) system. Kindly make a clip where we can house a subwoofer, mid and tweeter using electrical parameter to the best extent, so that instead pf 2.1, we can have an option of 2.0 channels. Thanks for guidance.
