i am a little confused when it comes to connection both the circuits together in cad for a schematic circuit diagram stage, in terms of the grounding of the outputs from stage 1 to stage 2. i am using proteus 7 and i have just joined the 2 together. instead of a pcb file do you have the circuit design file anymore?
10W R.M.S. Audio amplifier
32W Stereo Audio Amplifier
I dont understand what are you trying to say so let me just tell what i think u are asking. u will never touch -22 with ground or it will short circuit and your battery might get fire/damage. There is no such thing as voltage. its always a voltage difference (which means if I have a 22V battery/Supply it implies that the positive terminal of the battery is 22Volts higher than the negative terminal) so If you want to generate -22V All you need to do is connect the Positive terminal of your battery with the ground of the circuit (Ground is generally at 0 Volts so) your negative terminal gets 22V lower than it (0 - 22 = -22V). Its just a perception of it. I repeat there is no such thing as negative voltage.
What it will be if i connect the -22 and the ground to make the negative side of the power supply , and the +22 side o the positive side? it will work?
Power supply (+-5vconst & 0-+-12v variable)
but what if they made it with 1A and the sound was bad they will not know why and they will blame you and the tda2003 to prevent that you should say prefer 2A-3.5A power supliesjust saying for your own good
"can draw up to 3.5" is only in an extreme case. The IDEAL supply ratings should be voltage = 8 - 18V and the current = 3.5A.BUT always remember the IC will Never give you more than 12W output so whats the point of using a 3.5A supply? plus the whole point of this instructable is to make an amplifier, power supply is upto you people.I personally didnt wanted to buy a new power supply so used the one that i made already.
thats not it the iC can draw up to 3.5A right ? and you said use 12v 1 A your adapter will get hot and the IC will not work att full power
The issue is with supplies... try using a battery and there WONT b any distortion.. power supplies convert AC to DC and yet there is a little AC component left no mattter how many capacitors you use ... that is why there is distortion.. in high quality supplies it will be less but will be still there .. as you can hear it in the video link too.. but after that i used a lead acid battery and it worked like a charm.
is this IC i dont think a simple pot will do the trick i tryed in on my own before coming here and it didnt work you need some thing like this
i saw your comment i may be late but here is the thing: your amplifier is bad i made one like this from another web site and it worked fine i put a 12 v, 2 amp adaptator there is a distortion because i used 2 amps power supplies but never the less it worked
Hello!If I wire 2x (8 Ohm, 5 Watt speakers) together in series, will this circuit be able to handle the 16 Ohm resistance of the speakers?I took the speakers out of my old TV and want to turn them into a small speaker setup like the one in your videos!
Hey, just wondering if you ever had issues with the balance control not working properly.... on just not getting the right channel at all...
how much is the total cost of this amplifier?
Thank you :D
Hello. Can I ask if we can replace the pre amp circuit? Because the required ic is not available here. Thank you :)
how can i add the voice echo control in this, please guide?
Hi, Can I use only main amplifier for my speakers?
RC CAR (Parallel port interfacing)
hello brother, what changes i should make in the source code provided by you to run a RC helicopter... please helpFaisal HayatUoW Wah Cantt
maybe you can mail or whatsapp me;firstname.lastname@example.org+923449793574
yes I already have a 22k resistor going to ground after the capacitor just like how it is in the schematic, or should I add another resistor?
can i use the mic circuit with tda2050 amp ...
Oh and for the preamp I actually left out the pot for the balance control because I didnt think I would use it, do you think that thats what caused it not to output any signal
So the resistor to ground, should I place it before the 1uf capacitor where the signal enters the amp or should It be after the capacitor?The reason why I asked is because in the schematic there is a 22k resistor going to ground after the 1uf capacitor.
ok thats true, I built this amp and it works, when its not connected to my phone it makes noise when its connected there is a small hum but its not too bad can I get rid of that sound? Also I built the pre-amp but it doesn't work when I connect the signal to it and then the output to the amp I don't get any sound and I double check my wiring and it looks correct to me.
can I build both sides of this amp and tie inputs together then tie outputs to make 64 watts stereo amp? - ainsworthl
ok thanx... - Abbas arshad
in main amp ..can i use two 10k resisters in series instead of using 22k ........
can i use mylar caps for all non polarized capacitors..with same values ..thanx for your reply...
is switch 1 is vr1 's switch.....and tell me the types of capacitors u used in pre amp
whare is the part list for pre amp ( tone control circuit)
