So if you (and/or the band) go ampless, how do you hear the mix? Monitors, IEMs, is there a standard?
I suppose the standard is IEM. That's what I use.
How do you mix the mix you hear? Does it come form the board or is there dedicated hardware you bring?
Does everybody get the same mix from one box, many mixes from one box, or many mixes from many boxes?
Many mixes from one box. We bring a dedicated IEM mixer in a rack unit.
How many cables and box connections are we talking about?
Do you bring your own PA or do you send a multi track feed to FOH?
The rack we bring features:
1. A WiFi rack unit
2. A battery storage/charging system
3. IEM transmitters
4. The IEM Mixing console
5. An XLR Signal splitter.
The routing on stage is simple. We place the rack beside the FOH stage box and connect all the XLR cables from microphones and amps to our mixer. On the back of our mixer, there's a multicore coming out, which will be connected to the FOH stage box. That's the additional work that has to be done: Instead of plugging straight into the stage box, we plug into our stuff and our stuff into the stage box.
FOH works just like they are used to. We take our split of the signal, run it into our mixer (a digital one - popular models would be the Behringer XR-18 or X32R (or the Midas equivalents), or the Soundcraft UI series - a digital mixer with enough aux paths to run the IEMs. Every band member brings a smart device (I mostly just use my phone) that connects to the mixer and can control the IEM feeds, so every member can adjust their own IEM mix at any time.
Do you feel it is simple compared to the old ways?
I must admit that on bigger stages and festivals and such - basically anything where you can expect a decent monitoring system and a dedicated monitor mixer person that is available to you at all times - I don't mind playing a 'loud' stage.
What is a huge difference is small spaces and clubs. When the place and stage are so small that one generally uses the bass amp (in part) to carry the room, I find that when I am standing about three feet in front of my amp, whenever I turn it up enough that I can properly hear myself, the people in the back rows will drown in bass and I'm asked to turn down. Since I'm standing much too close to my amp, the lows can't properly unfold before they reach me and I usually feed off the reflections of the back wall.
On those gigs, both the audience and me enjoy a much better signal since everything is running through the PA system with properly placed speakers for the audience and I have my own mix on my ears. I usually mix my feed by starting with a balanced mix, something I'd enjoy for listening, and then raising the drums a tiny bit and the bass a tiny bit more - back when I started, I set the drums at +3dB and the bass at +6dB (starting from a balanced mix), but that was too much for my taste. Now it's just a tiny bit.
