I am trying to connect my mp3 player to the unit - I put a 1/8th stereo jack into the mp3 headphone output and the other end is a 1/4" stereo jack into channel 3 or 4. The music heard through the L1 keeps stopping and starting - what am I doing wrong?
yes the unit works just fine and so does the mp3 player - someone told me that I need a stereo jack for the output of the mp3 but only a 1/4" mono going into the Bose L1. I will try that and let you know what happens.
The 1/4" inputs on the Classic are unbalanced, so can only handle mono 1/4". As the graphic that ST posted shows, you need a Y-cable to split the signal into two mono signals and run that to two inputs on the Classic.
Connecting a TRS (stereo) plug into a TS jack will result in a short circuit on one of the output channels of the mp3 device; this is not recommended.
