TDA7294 is a chip amplifier that can produce best bass with high power output. I'm make a bridge of TDA7294 and add a lowpass filter in the input.
The amplifier will shake your room..!

Tda7294 ic nice ic is amp se sound quality jabardast . Cristal sound .bridge mode par 12inch ka sub woofer bhi chala sakte ha 24.0.24 5amp par maja aa Jaye
Big fan of your work.
Nice video
I think this is 100w rms because tda 7294 has a rms power of 50w . But very nice design and video. Keep it up.
160W pure on bridge mode
@@barlexrespectaizer452 how 50+50 is 100w i like your chanel but i dont agrre this . I sarch for it. Thx for the response.
why you not agree, this is from datasheet
BRIDGE APPLICATION
Another application suggestion is the BRIDGE
configuration, where two TDA7294 are used, as
shown by the schematic diagram of figure 25.
In this application, the value of the load must not
be lower than 8 Ohm for dissipation and current
capability reasons.
A suitable field of application includes HI-FI/TV
subwoofers realizations.
The main advantages offered by this solution are:
- High power performances with limited supply
voltage level.
- Considerably high output power even with high
load values (i.e. 16 Ohm).
The characteristics shown by figures 27 and 28,
measured with loads respectively 8 Ohm and 16
Ohm.
With Rl= 8 Ohm, Vs = ±25V the maximum output
power obtainable is 150 W, while with Rl=16
Ohm, Vs = ±35V the maximum Pout is 170 W.
@@barlexrespectaizer452 it can be becouse of the small power loss on the d mos s . I se a max of 140w at 45vx2
Wah mantap 👍
Bahut acchi sound aaraha he.board ka size kya he ?
Mantuuul gaeeees
Horeg,...top

Can't open your circuit file
This circuit suitable for 10 inch subwoofers..
ini menggunakan travo berapa ampere mas?
Missing some components list in this video
how much is the Stand by power supply?
Or to which pin does the 20k residence stand-by enter?
Superb!!
Bro, in which mode you configured the tda7294 ics to make this amplifier.? Is it in bridged mode or in parallel mode.? Please tell me.
bridge mode brother,
@@barlexrespectaizer452
Can i use this amplifier for my infinity primus 12" car audio subwoofer. Is there any problem while bridged amplifier connecting with 4 ohm driver ?
Masih ada pcbnya mas? Kl ada sekalian link olshopnya
Please share the components list
Chinese ic works?
Frequency of the low pass filter
Can i use 8 inch speaker
Het how about a stereo one!...no bridge!..
· Sir In this circuit you change the value of some component and tell you I want to run this circuit on 24 0 24 supply so that you tell the component. Use them or use PCB containing please tell me I am wating
no problem sir, you can use 24-0-24 transformer. But don't forget to use big heatsink on it. by the way use the 50v elco on the supply. I'm use 18-0-18 because very difficult to find a original ics in here
Barlex respectaizer ok sir· Sir, I did not even get the IC, I got tired of walking around
Barlex respectaizer thanks sir
Olá.. como faço para comprar essa placa..??
Is there any another resistor instead of 330k .
that's gain resistor, if your input signal weak you can change with more than 330k, like 390k but if your input signal strong you can use 100k or 220k resistor
I have 390k resistor can I use it
@@gokulg264 sure
Tnx sir u r great
Can i use 8-12 inch speaker as subwoofer will it decrease the bass intensity when increase the size of speaker
yes, but the watt of speaker smaller than 300watt
How about when I connect with 30-0-30v 5A
mantep semangt.. ayuhh gan.. kapan siap di produksi.. untuk di jual inih.. baguss nih.. he he
kira kira yg dibutuhkan pcb kosongan atau yg udah dirakit gan ?
yg udah di rakit.. aja gan..
Is mono o stereo?
Is It 4ohm Stable? And if so.. what is the output power at 4ohm load?
on datasheet 8ohm about 150W in bridge mode. may be about 170w at 4ohm
@@barlexrespectaizer452 Thanks For your reply. Acctually iam Confused cause in datasheet its says in bridge mode 170 watt at 16ohm.. how is it possible cause the impedance will be so high..
Use it on 16 ohom 35-0-35 volt 3 amp You'll get very low distortion and 170 watt
How much price bro
Sir how will I add frequency control to these circuit
if you need to build a preamp with freq control you can use this gerber or schematic link below sir :

If I used 30-0-30v 5A supply then how much watt will I get in output
about 200watt output from the transformer.. but it will be very hot

Thanks for the reply,
I need some technical help,
two TDA7293 IC PCB Board how much rectified DC voltage and amperes required to bring it to its full potential ?
You can use 22V DC up to 33VDC /5 Amp.. but you may need extra heatsink when use about 33V
@@barlexrespectaizer452
Thanks for the reply,
I was trying to Build 5.1 using three board, of TDA7293 (2 ics each) connected parallel to full Bridge rectifier (40000 uf) to a transform, but problem is my Board does not have on board rectifier it needs external rectifier so how should i limit it current to 5 amperes, as the transformer will be AC 22 0 22 Or 24 0 24, will be around 12 ampers
So what do you suggest how should i limit the current ?
Should is use two diodes of 2 amperes or 3 amperes (each board), on each individual positive and negative rail before it reaches the positive and negative terminal on board
Or simple 5 ampere fast blown glass fuse on positive rail ?
Or Both modifications will work ?
@@Royd20 maybe I'm late but the circuit will draw as much current as it need's ( ohm's law tells it ) so don't worry even if your transformer can deliver 12 amps the circuit will only draw vlose to 5 so no need for modifications because you will waste power and you will have voltage drop on the other components you wanted to add. so less power for the amp
Sir 18-CT-18
CT Meaning? And Transformer Ampere For Comfortable This Circuit?
it means 18-0-18 transformer.
you can use 5-10Ampere transformer sir.

Bos pesen satu kit subwoofer yg aktif yg bisa angkat speaker sub10/12 inc
cek di toped barlex audio gan
Ok gan
Gan untuk angkat speaker sub. Legacy 6"X 2 udah max belum suaranya?
bisa.. main 4 ohm
saya belum lihat suhunya berapa, pas digeber. biasanya 7294 terkenal panasnya... hehehe
sama itu belum ada gain nya ya gan?
benar.. sangat panas..
Can 7296 be installed instead of 7294?
Yes but 7296 only 60W and using 70 V power. So you need to change capacitors to 3300 mF 50V.Even 7293 better but 7294 is the best 100W TDA amplifier 😉
Mujhe 7294 circuit board de sakte hain
Pesan satu gan,hehehe
lihat di toped/barlex audio
Harganya brapa bang itu
Do I have to use preamp
for what sir ?
For these sub

Mas apa amplifier itu bisa di pasang ke speaker bazooka 6" x 2 psw 500? Saya bantu subscribe mas😊
bisa, tapi kabel +/- speakernya jangan sampai kebalik, soalnya system box nya isobaric
@@barlexrespectaizer452 siap mas terimakasih banyak
transformer information plz
18V CT / 10 Ampere.
You can up to 24V CT but you need more heatsink.
Bisa untuk ampli subwofer di mobil gak gan?
mesti pakai inverter lagi gan
Om, maksimal mampu buat mengangkat spiker berapa inch.??
12" saya rasa masih sanggup asal trafo bagus
Kalo pakai travo 20 amper sanggup apa enggak gan
datasheet nya maks out peak 10 Ampere.. lagian sya gak berani bilang tahan 20A soalnya banyak IC yang aspal gan..
@@barlexrespectaizer452 gimana gan cara bridge 4 ic tda nya
belum coba sih, soalnya itu kan mosfet bukan class AB
2x100w
plzzz upload the pdf file ....... thanks
On the description find schematics link, there is some pdf file
can i put +-35v ?
I'm not sure.. 24v is very hot
datasheet says up to +-40 but 35 should be it's limit
Use 35 dc ....24-0-24 provide 31v dc
Pcb size please tell me bro
8.5 x 5.5cm
Trus kalo mau nambain spiker buat vocal dan tribel nya gimana
tambahkan kit stereo nya
@@barlexrespectaizer452 oh berarti pake dua power..
Satu buat wofer satu lagi buat stereonya?
ia benar.. pakai trafo 5A murni udah bisa buat hidup ketiga ic.. kalau mau stabil pakai 10A
Ini BTL ya boss?
