    Hey, I recently purchased a MG30dfx to use at church because of its size and internal effects. Problem I am having is I want to use the emulated line out AND the internal speaker for stage volume. I'm sure I can make adjustments to the headphone jack to use both at the same time, but I am worried that doing so will put too much strain on the amp. Had anyone done this is have any suggestions? We are not using stage monitors, but in-ear monitors. Just wanting stage volume. Or should I just mic it ???

    That's no problem go ahead and do it. It doesn't strain anything it's OK.

    If you want to use the headphone out and send 1 signal to headphones and 1 to the house (because you're on a silent stage), then you need a small mixer of some sort.

    Here's one example. There may be cheaper options, but I found this in a quick search. This one can split any signal 4 ways, $65. Perhaps other members can offer a better suggestion, but my point is that you should use a mixer or some kind of proper headphone splitter, and never a Y cable:

    Welcome to the forum, as far as I know you can use line out and internal speaker with no harm whatsoever, I used to use the line out to another small amp.
    And had no issues at all.
    Cheers Mitch

    Solid state amps are not likes tubes the power section is a switch and gets hot if you crank it . the line out is not the problem . As long you don’t max it out all day you are good . I must be great feeling to be rock star to your church

    Thanks for the info! I plan on opening the amp up tomorrow and bypassing the switch on the headphone jack that turns off the speaker when I plug into that jack!

    The trick the the headphone jack is to plug a cable in 1/2 way, and it won't shut off the speaker.
    However since those headphone jacks fail a lot, bypassing is probably a good idea.
