Andrew Grayland and John Austin former R&D manager and one of the Technical Directors of Klark Teknik started XTA in 1992. Having overseen many of the benchmark products produced by KT, both Andrew and John felt that DSP (digital signal processing) technology could find a home at the heart of PA systems. At this time DSP was often disregarded because of its audio quality, but Andrew and John felt with the right algorithms and using 32-bit processing coefficients instead of 24-bit - what the majority of DSP designs were using - digital equipment could be designed that would sound very pure and clear. Were they ever right..
