NuuNoo Posted October 14, 2006 Report Share Posted October 14, 2006 HiI just bought a radio that has and aux/line in input. As expected, when i connect a jack to it (even if the other side of the jack isn't connected to any source of sound), the internal sound is disabled.I need to overcome this, because I need to have the aux input always connected to a audio source (TV in this case) and to have a switch to choose beetween internal/aux input sound.I tought that if putting a switch to open the line beetween the out source (tv) and the input jack would solve the problem, but as I said, when I put an open circuit in the input jack, it disables the internal sound...Can you help me? If I understand how the "auto-disable" works, it will help me to solve the problem.Many thanks Quote Link to comment Share on other sites More sharing options...
mvs sarma Posted October 14, 2006 Report Share Posted October 14, 2006 Welcome to the fourm As you rightly described, the aux input jack cuts the Radio detected Audio and extends the audio amp input to the externally connected cable. It is a mechnical disconnection as you plug the external input. why not you try to indicated thr model and brand name and if possible the IC used for the radio abd audio if seperate. this wold help in proper improvization--sarma Quote Link to comment Share on other sites More sharing options...
audioguru Posted October 14, 2006 Report Share Posted October 14, 2006 The input jack on the radio has a built-in switch.Simply re-wire it so that the switched wire is connected to your added switch. Quote Link to comment Share on other sites More sharing options...
