Small, personal mixer for live performance?
A band that I'm playing in has a mixing board with two separate aux outputs, which some of us in the band use to direct some of the instruments and vocals to two different wireless in-ear monitor systems; One for the keyboard player, and another shared by me and one other member (each of us both sing and play guitar). The other guitarist and I are using a single transmitter, each with our own receiver set to the same channel, which means that we both get the same mix, which is mostly our guitars and vocals, with just enough of the other instruments to ensure that we hear them.
The problem is that we don't fully agree on the levels in this mix. He's mainly strumming an acoustic guitar, while I'm playing electric and doing more solos and intricate stuff, so I really need to be able to hear what I'm doing, but when I turn my guitar up to a level that feels loud enough for me, he thinks it's way too loud.
So, a solution that occurred to me is that I could have my own small mixer for my own mic and guitar fx box (which has stereo pairs of both phono and xlr outs). Ideally I'd like to pass all of those signals straight through to the main mixer, but with a device of my own in between with its own aux output to drive my own in-ear setup. But I can't seem to find such a thing, except maybe some huge mixers that fill a table of their own. Maybe I'm thinking about this a little wrong, maybe I should be *splitting* these three signals instead, and running all three into a small mixer that defines a single output for my in-ear monitors? I know that there are Y cable splitters for XLR cables; Would doing this affect the sound going out to the main mixer at all, or might this be just what I need? Maybe all I need is some XLR Y-splitters and something like an XVive PX? https://xvive.com/audio/product/px-portable-3-channel-personal-mixer/
I'd love to hear any thoughts or experiences in dealing with this kind of thing!
