The 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.

Featuring studio-grade reverbs, delays, and modulations from Lexicon, dbx dynamics, and BSS graphic equalizers, the Si Impact comes fully equipped to mix everything from rock bands to stage plays. Also a 32-in/32-out USB audio interface, the Si Impact mixer delivers professional digital recording directly to your DAW, and comes with a free download of Ableton Live Lite 9.
