New York, NY (April 14, 2014)—Icelandic band Sigur Rós finished a two-year tour recently, with UK audio provider Skan PA using its new d&b audiotechnik D80 amplifiers to power d&b J-Series boxes with some Q-Series for fill.
Tom Tunney, Skan’s system technician for the three-week final leg of the tour, noted, “The most immediate thing we noticed was an indirect benefit of the active power correction, when we applied the ‘pull’ on the service with no gain reduction anywhere on the signal path, it just sounded clearer. The power saving was also significant; with 16 J-Tops a side run from D12s, we would normally see a draw of around 60A per phase; with the D80 we were seeing around 20A. I’d taken out a full Powerlock mains distro and the truth was I could have run the whole PA, a modest arena system don’t forget, off a 32A three phase CEE Form distro. And there’s another thing, we saw a big reduction of current down the neutral; where normally we’d see the sum of the three phases, this was more like it was balanced to the draw from just one leg.”
Packaging is another significant criteria for Skan, “We always look at space saving, at four channels in a 2RU module, each D80 basically gains you 4RU of space compared to the four channels of the D12. We have already redesigned our racks to accommodate this benefit. Adding the line gain from losing the d&b SenseDrive return wire to each cabinet, means we can now run 16 boxes off two of our Socapex signal feeds. Naturally there’s a truck space gain as well, and it’s not as marginal.”
