Nice work ,,❤

[@TechRallyofficial]

Thank you 😊

[@MuhammedsirajSasonic]

Nice quality ❤

Thank you 😊

[@GeoBass-89]

nice work. i like how you pay atention but... you need for that 5.1 amplifier few things : 1: power supply is not enough even for one chanel . you need 24v power supply and 15A minimum 2: you need some active filters there for each chanel in specialy subwoofer you will habe a big improve sound better than much home theaters 5.1

[@TechRallyofficial]

Yes, selecting a right power supply is important based on application and speaker ratings, for me 12v 5A is enough for small room you won't believe me it works really well i haven't seen any issue with it ,since its a Class D amplifier it is very power efficient, I am using only for desktop 5.1 output which has built in active filter so passive filter is not mandatory but adding it improves quality.

[@GeoBass-89]

@@TechRallyofficial yes, but if you put bigger power supply you Will improve much quality sound. Good job anyway

[@TechRallyofficial]

Thank you 😊

[@lunarz7117]

I feel using a arduino micro just to run an ARGB led ring light is kind of wastefull, so many pins are not used! Maybe program an AtTiny85 for just running the ARGB leds?

[@TechRallyofficial]

Yes, Using Arduino Pro Micro just for ARGB LED is not cost efficient, you can use any cheaper Arduino boards..😀 Thanks for watching...😉

[@yogeshsinghsonigra4054]

You can program alexa in Arduino

[@TechRallyofficial]

That is not possible bro..

[@supratimmondal5071]

You have done a great job keeping everything clean and organized. Kudos, and keep it up! 🤍

[@TechRallyofficial]

Thank you 😊...

[@diytricks7234]

Nice work, I did a similar project, you may need a fan if you want to reach the full potential of those boards at 24V the heatsink is not sufficient.

[@TechRallyofficial]

Great, yes fan adding fan will be a better option 👍 😀

[@thelord-rq6rv]

Does This really give Dolby Digital Surround Sound Through Pc Input?

[@TechRallyofficial]

Your motherboard should support 5.1 analog audio output for that..

[@thelord-rq6rv]

@@TechRallyofficial no I have sound card that support but I'm still confuse do i need 5.1 decoder or the sound card can work.

[@TechRallyofficial]

@thelord-rq6rv 5.1 sound card will be better but the software should have option to control individual channel volume, Decoder will be cheap option. But you will not able to control individual channel volume form pc

[@Raff_Vid]

Good job🙏, but i see that youre using one of those 5.1 channel speaker that usually dont really have bass, please filter some bass only to the satellite speaker. Also instead using arduino, use an led visualizer they are quiet cheap (or maybe find an rgb led that dont use arduino)🙏

[@videopendek2421]

this is an interesting video , very recommendation to watch

[@TechRallyofficial]

Thank you 😊

[@rohitjasuja.mumbai]

Can you make a 7.1 with audiophile components having 100 watts output per channel at 8 ohms? To make it interesting we can add the ESS9038Pro DAC board also in the unit. I can pay for the entire setup and your expertise.

[@TechRallyofficial]

Sorry currently i am not doing this service, may be i will try in future, Thank you 😊

[@die3ddrucker]

Sub ❤ nice work! Keep it up

[@TechRallyofficial]

Thank you 😊

[@AswanthSharman]

Can u explain which one is the subwoofer out and how many watts actually it is?

[@kayjay4561]

There are no links in the description for the parts you used to make this? Though the video mentions that such links would be in the description? Can you provide those links as a comment, maybe? Thanks. This is an awesome project.

[@TechRallyofficial]

I will update and comment here Thanks

[@kayjay4561]

@@TechRallyofficial Thanks. In the mean time, would it be possible to provide either a link or the specific brand name for the 100k 6 gang potentiometer you used in the video?

@@TechRallyofficial I can't find this where I live, so I am going to do something like this - kzbin.info/www/bejne/ipysinigh8lpp8U. Do you think this will work? Thanks.

[@TechRallyofficial]

Even small force could damage the carbon in potentiometer, its not worth the effort also volume control will be uneven. Try local amplifier shops to get. If you have access to aliexpress in your country it will be better option to get from there...

[@darkmightygaming5280]

Is this standard 5.1 😅 cause im planning to make one

[@TechRallyofficial]

Yes, its standard 5.1

[@jacky_cola]

Hello, I have a Question. I have tried a very similar setup, but whenever I try to plug in 2 cables there will be humming/buzzing nosie. The sound will work but the noise is very loud? What can it be and how to prevent that?

[@TechRallyofficial]

This might be because of your SMPS power supply or poor grounding loop in your audio source. Try reducing the gain in amplifier board potentiometer. And make the audio cable doesn't interfere with other display or power cables.

[@sreejasajeev-artsandlifest8321]

Bro, i have made a similar project., But i am not getting enough bass while playing films with vlc, 123player etc. The bass i am getting is very low ( from center/SW port ). Do you know what must be the problem?

[@TechRallyofficial]

This a common problem with PC audio output, you need have the realteak audio driver and in that you need to enable Bass management and enable room correction in that increase the gain for subwoofer.. THANKS...😊

@@TechRallyofficial . Bro it worked⚡⚡⚡⚡. Thank you soo much 🥰

[@TechRallyofficial]

Super bro..✌

[@diytricks7234]

I think it depends on the sub you are using, normally the PC should be able to generate the required signal

[@parthasarathimanna8790]

Nice ! What's that thing of boAt you used?

[@TechRallyofficial]

Thanks, It's 3.5 mm audio cable

[@davidbilec3009]

this is not 5.1 its simply bridged stereo sound to a 5 speaker and 1 "sub" connection. It is not surround sound which 5.1 is but youre instead just surrounded by sound which is not the same thing.

[@TechRallyofficial]

Its true 5.1 Audio not the bridged or simulated 5.1 sound. See the video fully, i used the 6 channel output from PC which has seperate connector for front, rear, center and sub...

[@ixrvalor0812]

i have a question , please answer me, if i have 3 amplifiers like that need 19v 4amp per amplifier, can i use all three in only one 19 v adapter

[@TechRallyofficial]

Class D amplifiers are high power efficient You can use all 3 in one Adaptor, If you use high power drives for all channels you may require high power Adaptor.

[@ixrvalor0812]

@@TechRallyofficial my question is if i have 19 v adapter 9amp , will the 9 amp divide by 3 for the 3 amplifiers or every each one will get 19v 9amp

[@TechRallyofficial]

Power will be divided based on load.

[@yogeshsinghsonigra4054]

Current will get divide in all three amplifier, each one will receive 19v 3 ampere

is it not TPA3116?

@@TechRallyofficial thank you, in my case, I only have one amp board (same board as yours) which I want to control master volume. to INPUT SOURCE, does that mean the 3 pins on the amp where I will be connecting the Bluetooth audio player? to AMP channel (ch1 and ch2), does that mean where I connect the speaker from the amp?

[@TechRallyofficial]

In that 3 pin one will be groud and other 2 pin will be input to amp, ground pin should be connected to the left side pin of potentiometer and other 2 pin will connected to the center pin in potentiometer and input audio source will be connected to right side pin of potentiometer..

Sorry i am currently not selling anything for now, i will try to do in future. Thanks 😀

[@dailydoseofkerala3155]

So basically u are using your pc as a decoder.. Then amplifying each channel comming out from the pc.... Great job... But this can only give 5.1 out put if you have a pc with you....and also using aurdiuno for led was an overdoing. 😅😅

[@TechRallyofficial]

Exactly yes... Aurdino was lying in shelf for long time it needs some use..😝 Thank you 😊

[@nvk1630]

5.1 channels and 2.0 input. what are you doing?

[@TechRallyofficial]

There is no 2.0 input, i used 3 amps each has 2 channel and 3 audio input jacks each 2 channel, 6 channel output form pc via 3 male to male audio jack cabe each 2 channel. This is pure 5.1 audio.

[@nvk1630]

Ok that good bro, but your connecting bluetooth only 2 channels.

[@TechRallyofficial]

Oh ok now i got your point, just for demo i connected via mobile for 2 cannel, subwoofer + center speaker alone will work. That only for demo because i dont have 5.1 source to test on table, finally i connected to my pc for 5.1 source... Thanks

[@nvk1630]

@@TechRallyofficial you should use "HD Audio Rush" to decode at the input, and it is called one av receiver.

[@rawgen]

Do you use 5 amps? How you set the control to center and subwoofer canals in a single dual channel amp board?

Yes, i use 5A power supply The board has the gain control for each channel, using that u can control center and subwoofer channel separately...

12v 5 amps not at all enough.

[@TechRallyofficial]

Its only class D amplifier, which will not cosume more power like transistor based amp, I am using this on daily basis so far i haven't seen any audio distortions.. Its recommended to use high power if you are using high power subs.. Thanks 😀...

[@aswinsura3851]

@@TechRallyofficial what ever it is but that board is rated at 100w+100w and u have 2 of them which means total power consumption will be 400w if the efficiency is 100%.yes its class d chip which means that clipping feedback ckt and build in to it.if u connect 12v 1a will also work with out clipping but relative power output will significantly lower.

[@TechRallyofficial]

100w is just a peak power it doesn't mean it consumes 100w at all time, Even if you use at high volume it consume only 40w max if you go maximum 100W than it is more that sufficient for even a big house and neighbours to complain about loud volumes. Selection of power supply is important also should be based on your application. Thanks...

No cooling fan 😮😮😮😮😮

[@TechRallyofficial]

Initially i planned include cooling fan but while testing it dosen't produce any heat, because it as more efficient class D amp and i used only 12v 5A power supply It my primary amp for my PC and its amazing

[@abhijitsarkar6960]

This is not a 5.1 amplifier ...there is only 4 channel and power supply must be 19volt - 24 volt

[@TechRallyofficial]

I used 3 Amplifier modules each has 2 channel, the board works from 12 to 24v.. I wont fake or lie anything in my videos..

[@abhijitsarkar6960]

​@@TechRallyofficial.....I am sorry to say I didn't see the 3rd amplifier which you used one on top of the other 😶

[@mikecox05799asd]

you said its 600w. its no where close to that maybe 25w at best. thanks for being a liar.

[@TechRallyofficial]

Sorry for not cleary mentioning, Peak power is different than power consumption, i used TDA3116d2 based amplifier boards which has total of 6 for each channel you can search in Google for power rating. I used 12v 5vamp power supply which is more than enogh for my home use since i have only small speakers.
