Se incalzeste finalu repede si nu da semnal in boxe.Care sa fie ptoblema?

 

Daca tot exista o categorie despre amplificatoare, de ce n-o folosesti !? Pe viitor mai multa atentie te rog! Multumesc!

din datasheetul tda8560q: " SHORT-CIRCUIT PROTECTIONWhen a short-circuit occurs at one or more outputs toground or to the supply voltage, the output stages areswitched off until the short-circuit is removed and thedevice is switched on again, with a delay of approximately20 ms, after removal of the short-circuit. ................The power dissipation in any short-circuit condition isvery low.......... approximately 40 mA. "morala - nu ai nimic in scurtdaca se incinge repede e "dus" , schimba-lam avut de-a face cu acest IC si cand era ars asa facea- se incingea de moarte :smt003

e bine sa studiezi si datasheet-ul acestui integrat, cel de la http://www.semiconductors.philips.com/pip/TDA8560.html sau vezi documentatia kitului de la http://www.adelaida.ro/pub/Docs/AD_005.1.pdf

 

foarte posibil e sa fie radiatorul subdimensionat asa ca-i poti pune unul mai mare si/sau un ventilator (cooler) de sursa de calculator

 

banuiesc ca-l alimentezi la +12V ....si ca ai pus radiator :partyman:
