Detailed PA notes:
FLOYD OUT FRONT
A glance at the Floyd's exceptionally neat setup shows quite graphically how much live performance technology -- especially sound reinforcement hardware -- has advanced since this band filled its first Transit van. When Pink Floyd first took to the road, the typical touring sound system amounted to little more than the gear today's local bands might use to play a small bar or club. Standard issue were Vox AC30 and AC50 backline amplifiers and cabinets, which, augmented by WEM (Watkins Electric Music) 4x10 inch speaker columns, would also form the PA system. It was, indeed, with just such a system that the Beatles played their famous final concert at the giant Shea Stadium. You might also have enjoyed the benefits of a small mixing desk -- although these were not so common on professional tours until the relatively high-tech days of 1970/71, when Bill Kelsey marketed his first touring mixers. Bill once recounted the story of how, on a Floyd tour in the early '70s , he pioneered the active DI box; he worked out the circuit, studiously soldered the components onto a small square of circuit board, and taped the whole assembly into an Old Holborn tobacco tin. Today, as you might expect, tobacco tins are not widely in evidence on the Britannia Row Productions' equipment list.
Today, the Pink Floyd PA consists of slender, custom-built towers either side of the stage dome, on top of which sit curious 'bonnets' -- actually pig-pens, housing the famed inflatable hogs which, eyes blazing ominously, bob and weave high in the air. They also serve a practical purpose -- under each porcine belly there is an implausibly small cluster of Turbosound's Flashlight PA cabinets.
Floyd's touring system has been adapted slightly from its original specification for America, in the light of experience. The delay towers were eliminated in favour of a slightly expanded main Flashlight PA. Controlling and powering this, and the on-stage monitoring system, is a large inventory of Turbosound's dedicated Flashlight system controller racks. There are two Yamaha PM4000 mixing consoles for the main front-of-house mix, a PM3000 which serves for quad effects mixing, and a specially-built Midas XL-3 desk, which contains a unique quadrophonic panning centre, complete with dual joysticks.
If you can fit it into your home, than it's perfect speakers for Pink Floyd.
