More details from Allen & Heath (www.allen-heath.com):Koch’s relationship with Allen & Heath began nearly a decade ago with a GLD-80 and has continued to evolve alongside his business. “A long time ago I got an Allen & Heath GLD, and that was kind of the start of liking them,” Koch said. Today, Koch Sound’s inventory includes an Avantis alongside a CQ-18T, allowing him to tailor each production to its specific requirements while remaining in the Allen & Heath ecosystem. In part because Koch had attended Allen & Heath University training sessions, he felt comfortable teaching how to use the Avantis during the event. The Homer Harbour festival also showcased Allen & Heath dLive at the touring level, as the headlining act arrived with its own CTi1500 system, resulting in two Allen & Heath consoles at front of house.
