Dave Rat - Roadies in the Midst

Each trade has tool set. The fundamental and most basic item around which that craft is formed. A carpenter's hammer, a logger's ax, a fisherman's rod. The older the craft the more archaic the tools tend to be.

For a chef, it is the knife, Here our head caterer Jeremy's love for these handmade Japanese folded steel knives is so deep it literally brings him to tears as explains their quality and craftsmanship

Speaking of crafts and using tools, here you can see the proper usage of an XL4 as an elevation platform while foot mixing.

Missy is our tour manager Adam's assistant and doing a fine job of making that Rat hoodie look awesome.

Ok, you are at a gig, option 1, head to your seat and watch the show, Option 2 hop into kiddie pool fully clothed with some dudes. Hmmm, tough tough decision.

Fortunately though, someone from the radio station that came up with this brilliant idea relieved us of this unsightly obstacle soon after the show ended buy dumping a torrential waterfall down the seats creating a 3" deep lake for the subs to sit in and the crew to saturate their shoes in during load out.

Check out this mirrored drum head!

Ok, link of the day comes from my good friend Jamie Anderson who heads up Rational Acoustics. While I roll with my basakwards low tech and analog ways, Jamie does Smaart training and is all up on the other approach. So when he stumbled upon this gem, he knew where to send it. The ultimate analog delay!

And on to less serious stuff. When I was laying out the initial Vortex designs, I started with what seemed a good place. Take the B sub and place in a conventional manner, then build from there. I really try to break down those barriers and open up to all possibilities but looking back I realize that it had no real logic other than just clinging to something familiar. And that decision made without fully justifying meant that the design was a bit less optimized than it could be.

Below you can see a simplified drawing of what is going on with the summations and cancellations of the Vortex setup. On the left side you see a counterclockwise setup on stage left. On the right side you see a counterclockwise setup stage right. Though the setups are the same, notice how much cleaner the left side is.

Green arrows represent summation, Red represents useful cancellations in the band that we are reproducing and gray is imperfect summation with some cancellation. The arrows are drawn from box center through box center. The arrow lengths are meaningless.

One of the issues we had with the original setup was that I was getting a bit too much sub off to the sides. So I started pondering and realized, hey wait, let's reverse directions of the Vortex and it should move our primary focus to the deep corners of the arena where we want it and paper and sure enough, the real world result matched the pen and paper prediction!

Ha, meet Juan (lampi), Robert Rat (stage), Josh (carpenter), Jim Rat (foh), Derek (automation - stuff that moves during the show, like Travis), Randy (Famous Stars and Straps promo), Jeremy (food), Me (trouble coordinator), and Justin (automation)

And so ends another terrible day at the office.
