audioguru Posted July 19, 2005 Report Posted July 19, 2005 Hi Hilario,Welcome to our forum. ;DThe LM386 is a low power audio amp with enough gain to be an intercom station. If you use two stations connected together then they will make acoustical feedback howling, unless you use a manual push-to-talk switch or an automatic circuit to detect a voice and switch it through.What design calculations do you need? ???
