Dear all,
I am from one of the begginers in electeonics hobbysists. I have some knowledge about electronics. I decided to build 2.1 channel amplifier with TDA7377 + LM4558D using schematic given on following site -
Circuit power audio amplifier with TDA7377 2.1 – Stereo + Subwoofer 2x 12 Watts + 37 Watts | Xtronic Free Electronic Circuits and Informations
Now, I have two 10w 4ohm satellite speakers and 50w 4ohm subwoofer. But after assembling circuit sound is anyway not coming. I am using 12v power supply. And usb mp3 player as sound i/p. But there is noise only. Please help me with this circuit. Whether LM4558D requires negative (-12v) power supply??
Please help.....!!!
