Hi Can anyone help me I am trying to get my E-60 to stop playing out of the speakers when the mono line out is pluged into my mixer for recording on my pc. Thanks ahead of time

Insert 1/4" Plug into headphone socket.

Thanks for that quick responce, thought that was for the headset and the mono line out is for attaching to external recording, shocked.

MY E 80 has a switch right at the jacks for turning the speakers off.
If you don't have this switch then just take any 1/4 male plug best with out any wires soldered to it and plug it into the jack. That opens up the circuit to the speakers.
You can just plug your earphones into it and that will also open up the circuit to the speakers.
