Electrics. Can you use a preamp for ear plug listening?

I think about owning an electric violin from time to time.  I'm really impressed with the new Yamaha YEV-104, but looking at it, I realize that there is no place to put a battery in it and so you probably can't use earplugs with it.  I would hate to be tied down to an amplifier.  Preamps are pretty portable and I wondered if it was possible to listen to the violin using a preamp.

Can you use a preamp for ear plug listening?

That would be a great solution as long as the preamp or effect processor has a headphone or monitor out jack. Let us know what you find out.

I was hoping that the output jack on  the preamp might serve as an output jack for an ear plug.  I take it you've never tried that.

Maybe somebody will post some insight here on the idea and we can both find out at the same time.

I rather suspect the "passive" output would be directly from the pickup (most likely a high-impedance pizeo transducer).   You would be lucky to get any real volume in an earpiece from that, and the sound from the actual strings, even on a silent violin would probably be just as loud!.   I suspect the answer is indeed to use a pre-amp (even combined with some FX capability).   Most such boxes will support different mechanical input plugs (like DIN style for some phantom-power microphones, and the more common 1/4" jack plug).

I suspect you would want -

(1) A screened 1/4" to 1/4" cable with male plugs each end between fiddle and pre-amp

(2) The pre-amp itself

(3) Either a set of "studio" headphones already terminated in a 1/4" jack plug, OR, if you hare using an "earpiece" with 3.5mm jack plug - you would want one of these - 

a 1/4" to 3.5mm converter plug - plug THAT into the pre-amp output, and your 3.5mm ear-piece plug into the other side -

EDIT:  Image shows stereo jack - your EV is a monophonic source - it doesn't matter - the jack SOCKET on the preamp may be mono OR stereo - and if stereo, then effectively both the "Left" and "Right" channel on your headphones/earpiece will be fed with an identical signal.

After a little thought, it comes to mind that mixers have preamps built in. Also, most mixers have an output for phones with a volume control. So why not get an inexpensive mini mixer such as this these?

OK, that answers my question, I think. A preamp will provide the wattage to listen to earplugs, maybe headphones. Fiddlerman, your examples are of the sort I am thinking of. What I would really like is something I could clip on a belt or hang around my neck or something. I see there are a lot of preamps with this sort of portability.

Here is another gizmo that looks promising:

Yeah - that's a neat little dude !

I'm not so fussed about portability, and for my EV I use a Boss ME-80 FX box complete with stomp-pedals - NOT the sort of thing to sling around your neck though, LMAO....

Maybe a nice product for monitoring yourself but no possibility for an amplifier. Or did I miss something? Just one output.

Yup, @Fiddlerman has a point there - but - if that's all you want it for ("silent, but with headphones") it would do - basically - with it all you're doing is adding what would be inside the basic circuitry of an EV which has an inbuilt battery/preamp compartment.

If you DO want to play "live", to an audience, then sure, it would have to be amped-up - or - even with that little box (which looks like it has an actual 3.5mm earpiece jack socket), you COULD drop the earpiece and feed the box output to your home stereo/sound system.  Not portable of course, but, will let others share in your playing - the sound from decent speakers is quite quite different from just a set of earphones...  

As it happens, that's exactly what I did when I first got my EV (it has an inbuilt preamp) - I just made up a long lead to connect into an input socket on my surround sound....    sounds pretty good like that !  LOL   That of course cost me nothing to try out - I have a stack of leads, connectors and adaptors kicking around.   It was THEN I decided I really wanted the FX box...  LOL

Whatever you choose, it really is worth taking the time to think it through, and get something that truly serves your purpose, now, and for the future.

Yes, on both points. That's what I'd be looking for.
