Firstly, apologies if this info is posted elsewhere. I've read most of this thread and done searches but can't find an answer. Happy for a link to be posted where I can read up if there is one.
A couple of real world questions.
As a band, we're rehursing with IEM as were in the drummers music room at home. He has a V kit, bass/guit are di'd so it just the singing anyone else can hear. We're using a Soundcraft digital system so we all have our own stereo feeds. Works perfectly (and saves on rehursal room fees!) and we take this system out live with us. However, we've not used the IEMs live yet.
So what happens when we do a 'small' festival with multiple bands i.e. not our gear? What's people's experience with this? Do we ask the engineer to unplug from the monitoring/stage box and use that as a feed into our own headphone amps? What happens if there's only 3 aux sends and we're a 4 piece. Do you forgo IEM in these situations (in this case the kit would probably be acoustic anyway).
Secondly. What do people do with the lead from the earpieces? Inside your top? Hanging loose down the back? Currently I'm not wireless, so have a dual guitar lead/headphone lead situation going back to the amp/headphone amp (cable tied together) so can unplug the earphones when I take the bass off.
Finally, how do you communicate with the band on stage, say if there's a set change or need to say something. Talkback on stage? Possibly an omni mic in front the drums that picks up just the stage.
Hopefully someone with experience using IEMs will have come across these situations already.
