Generally I can be done making the measurements and corrections in less time than it takes me to set up the rig. Takes me a solid hour (or more) to get the SIM set up and programmed, faster on a tour, but then so is the Smaart rig. My measurement rig is up and running in about 10 minutes, another 20 for the mics, stands, and cables. I have had regular access to a SIM3 for the past 4 years. (Ivan, the loop back is here, and it works with the MOTU just fine.) The Octa Pre is the must have I/O for multichannel Smaart rigs currently. The rest of the time I use the mics to see various systems in their zones individually and with the entire system on (like what Ivan describes). When setting delays between systems, I'm still using 1 mic at a time. Can you say heavy combing? Some of us have been experimenting with averaging out the ground bounce and that works quite well too. This trace is good for EQ decisions, especially with line arrays which tend to have a radically different response from seat to seat. This is where several transfer functions are averaged together to show the common attributes of the speaker/room. I use 3-4 mics for live spatial averaging. and I'm very pleased with them, but 4 ECM8000s will work under most conditions. I'm currently carrying 1 M30, and 4 M23s, all pretty much brand new. The result I get from 4 is almost as good as 6, but saves 2 cables. Lectrosonics makes a great system for that, which I have yet to budget for, but have used successfully. Dragging 6 long cables around an arena is a drag. I work fast unless I'm investigating something new (experimenting), or documenting/ organizing my traces for some other purpose. I have to be done with my work quick because I do not live in the install world but a few days a year.
