hi everybody . I purchased a sammichSID 2 years ago and i realized that i only hear the output from only one speaker when i insert the jack (stereo jack) to the bottom / all the way down, however , if i put / plug the cable halfway i listen by 2 speakers (but its like a mono sound i think). So , can somebody explain me which kind of jack cables i need ? maybe stereo jack ? perhaps i have an output issue ? I have donde the same with another cable and with 2 headphones and the same problem : cable inserted / plugged to the buttom . Thanks very much
