Hello all,
Maybe a bit off topic, but maybe you can give me some help...
I am trying to add an aux input to a boombox radio I have at home
I have not found the schematic of the main board, it's a MX-Onda
MX-MCP6428Mp3. So far, I don't want to use the tape player or the
CD player. I want to modify the circuit on the radio Mode.
It has an analog volumen pot with six pins, and the following ICs,
SA2111 is the radio IC, and NEC1316C is the power amp IC.
I can't see any sort of Jumper wire that would allow to connect an
stereo 3.5 female Jack with 'two poles' to keep the radio on, but
connecting an aux instead of the radio. Everything seems printed
on the board.
I have tried to connect directly my smartphone to one of the inputs
of the NEC1316C ic, but the sound is barely heard, It's like the IC
ignores that signal, and the radio signal keeps there. The volume pot
does not improve the situation. Something is going on, but I am lost.
Anyone here has any clue how can I make It if it's possible?
Thank you very much for your attention. Thanks for stopping by.
Cheers
