Hello!
I would like to know where I can do a solder to connect a jack input on this device which does a very good job, except than that. It does have a mic input but it's a mix/mic input that results in a very low volume. Apparently it could be done between the fm preamp and the main amp. But well, I don't know where it is, when I open the beast. Anyone knows more than me about this kind of boards?

I used mic mixing jack many times into different boomboxes and don't have problems with sound.
Of course sound is mono, but from 2 speakers.
