Preamp circuit is TDA from the company Philips. His involvement This circuit can with a minimum of external components to change the volume, balance, treble and bass. Its advantage is that all settings adjustment is performed by changing the Its advantage is that all settings adjustment is performed by changing the voltage on the corresponding pins of the circuit and that for both channels at the same time. Thanks to this, it is not necessary to use high-quality tandem potentiometers, which are expensive, but just simple potentiometers.

Pls HELP.. User Name Stay logged in? Big trouble with TDA! But it was absolutely fiasco! I cannot get any pot over mid level When I get any pot to upper level it appears a big noise on speakers and no music! What's the problem? Did I make a mistake?
Or the circuit is mistaken? Attached Images tda Find More Posts by Dxvideo. I have used these chips and usind one of TDA in a tone control my experience suggets firstly you should re-check pcb design, connections etc if things don't work out try changing the CHIP itself. I already checked PCB and other connections. And I changed the chip ones. At full volume the pot sends 4.
And it makes 22dB. But if I can limit to 2. Does it cause the problem? In fact, I must use this chip to remote volume control by wire. Do you know an alternative wired remote control a simple way pls? I would ve if I could find the problem, however since I am unable to locate the problem only thing I could suggest is usage of alternate chips like LM Thank you very much for your assistance.
But as I know, LM cannot handle over mV signals or it can handle but it makes distortion at this situation Attached Images clipboard. Yes it does! The audio source has it's own noise, no matter the signal level. TDA will amplify both noise and signal. I hope you can adjust the input volume of youre audio source. Please be more specific about what is your source signal cd-player, PC etc.
I use the same circuit in my amplifier and I had the same problem. The divider worked like charm! BB code is On. Smilies are On. Forum Rules. All times are GMT. The time now is AM.
