This will probably get moved as I'm not sure where to post this question. I know it's not about recording either, but everyone here has given tremendous help for all of my questions before, so I figured someone here could help me out.
I'm a drummer and I just picked up some Shure E3 in-ear monitors. I want to use them live obviously. I need something that I can use to regulate the volume in my ears. I know the basic stuff about headphone taps vs. headphone amps, and passive/line vs. active/powered signals. Ideally I would like something that I can use for either situation, because I believe that with the places I play and will be playing, it's really a toss-up as to whether their floor wedge drum monitors are powered or not. I also know that if I need anything special or something different from the norm from a soundman, well most of them wouldn't really be willing to help.
I know an amp wouldn't help me with an active/powered signal, but would a tap help me with a passive/line signal? The taps are passive devices, so would the line signal be strong enough to at least let me regulate my volume? If so, sounds like the tap would work for me. If not....well, I'd really hate to have to buy two separate pieces to ultimately do the same thing. I guess more venues use passive speakers for floor wedge drum monitors, but I could be wrong.
Thank you in advance for the help!
