I've had a couple of responses from Line 6 Support, but I'm not sure that my question has been addressed....

First, I have tried to reset to Factory Settings   (Hold "A" amd Power On)

Let me retry the situation.

Playing a MP3 thru the  CD/MP3 jack on the back of the LD150...

If I am using headphones this work perfectly...

If not using headphones, if the MP3 player is running on power-up of the AMP....

It will play for a second or two thru the speaker and then quit... turning off the amp and then turning it

back on will play MP3 sound for another second or two thru the speaker before going silent.

I suspect there is a problem with the AMP as I suspect that it *should* play the mp3 signal thru the main

speaker, correct?

I had my bass plugged in... it was working just fine !

I had no .mp3 thru the speaker, but had both bass and mp3 thru the headphones....

NO, I know better than that !

What I am saying is....

With my bass plugged in the AMP and working....

And my mp3 played plugged in to the back of the AMP and working....

If I DO NOT have the headphones plugged in....

I only get my Bass out the speaker....

I DO NOT get the mp3 out the speaker...

If I plug the headphones in....

I get BOTH the bass and the mp3 in the headphones....

Keith

Thank-You !!

That is what I suspected, but I bought it off a friend and never knew if it was that way since day one or not.

Before I hauled it in, I just wanted to make sure that I understood how it was suppose to work.

Maybe I will get a chance to check-out my HD400 this week-end and make sure it functions properly, too.

Keith
