Great thread. There’s another really cheap, easy solution, too. In addition to the methods mentioned already, like a dig. board with several aux sends, or boards like the Mackie and QSC that have phone apps, there’s a pretty neat, cheap solution: Rolls PM 351. Costs about $80, about 5" x 3". It’s pretty clean, I haven’t noticed any signal degradation at all. Fits on your mic stand, has three inputs… 2 stereo and one mic. (No EQ though). So you plug your inputs into the Rolls, and it passes all 3 of those signals on to the snake and the board, and “reamplifies” them too (it’s active and uses a wall wart, I think it’s 9-18v). You can either use IEMs (2 headphone jacks, which is nice) or send it to a wedge.
I’ve been using one for about 3 or 4 years, in bands with both wedges and IEMS. Typically you take the board monitor mix and it goes into channel 1 (stereo). If each player has their own aux mix it works great, or you can have a “base mix” that is relatively evenly balanced. Your Mic is channel 2. Your instrument is channel 3.
So even with a “base mix” on a board with only one aux /monitor send, each player can control the volume of their mic or instrument. In one band that uses wedges the stage volume was all over the place… so I just turn a knob and I can hear myself again. If you’re a keyboard player, as many on here seem to be, you can use a better small mixer in place fo the Rolls, as some have mentioned.
Another thing is pitch. Some people go off key on IEMs. You have to try several things to correct that. ususally it’s that the singer doesn’t know what a good IEM mix really is, their mic is either too hot or too low. Sometimes if you roll off the bass it reduces pitch being flat. Having the right mix is crucial… in one band the normally on-key singer was suddenly flat on everything… and i mean everything. I finally put my own IEM into his aux feed, and I was shocked at how bad the mix was (he set it up with sound guy during sound check)… everything was full on, bassy, his mic was getting lost… he had basically directed the sound guy to mix like he was mixing for FOH or a final mix, not for singing. Everyone’s different but I have my mic about 6 db or more hotter than the rest of the band, the drums are maybe 3 db lower than a normal mix, and my instrument is maybe 3-4 db hotter than the band. Sometimes bringing the bass down about 3 db helps if pitch is an issue. Stereo is great, and I strongly prefer it if there are enough aux sends, but I’ve used mono too… not a big deal… as long as my mix is good I can sing on key either way.
Personally, I will never go back to a wedge… I can finally hear everything, balanced in the way I want it.
We also use a Presonus 16.0.2 board which saves up to 100 presets, so we use one preset for each song… I think all dig boards do that now. So my mix is a little different for different songs, and on the hardest songs to sing I probably have my mic a bit hotter than normal.
