WHEN I TAKE MY HEAD-PHONE PLUG OUT I GET NO TONE OF ANY TYPE FORM MY QUATTRO--GREAT TONE WITH IT IN. AT TIMES I LIKE TO HUNT WITH NO HEAD-PHONES--ANY SUGGESTIONS---AND THANKS
my Elite will do this sometimes.I will just un-plug an turn it off an on a few times an just few it on for a few sec's an then the speaker will start working. no idea why it does this.If first start the machine up without the earphones plug in the speakers works fine,I only have a problem if I have the plug in first then pull it out.
I'm not familiar with the Quattro, but if I want to use my Ace250's built-in speaker, I must remove the earphone plug adapter........otherwise, NO SOUND ! lol
