singing of the anthems etc. CH: Sounds like you needed to fashion some trolleys. SWA: Right. These are five-element Kudo arrays – 18 positions in all – which are quite tall. And to manufacture a trolley to get them onto the field and then on the floor was quite expensive – and I thought spending 30 or 40 thousand dollars in a pretty limited budget to get the PA off the field in a hurry wasn’t good value. There must be a better way. The ‘better way’ was to use typical courier-style hand trolleys for the subs. And then a lot of time went into coming up with a set of rails that bolted onto the back of each Kudo array. And that enabled the array to be rolled onto a trailer and three or four of these trailers to be hitched up in a line and then taken off with a Gator.

• Up to 150MHz tuning range • 256 bit RC4 signal encryption for secure audio transmission • 2-channel digital true-diversity receiver • No Compander (used in analogue systems): higher sound quality • On-board DSP per channel (Compressor, EQ, Limiter) • Quick setup via infrared data link to the transmitter • Graphical spectrum analyser helps find clear channels • Remote monitoring and control via PC

CH: Like collecting shopping trollies. SW: Yeah, that’s right. Shopping trollies that weigh half a tonne each! But it worked really well. I mean, they cleared in nine minutes!
