Si ImpactThe Soundcraft Si Impact is a 40-input digital mixing console and 32-in/32-out USB audio interface that supports remote iPad mixing using a proprietary app. The console is designed to be as simple as an analog mixer, but offers workflow enhancements such as the FaderGlow system, which illuminates each fader track in different colors to provide at-a-glance status information on precisely what the fader is controlling.
