The legendary British sound
From humble beginnings in London more than 40 years ago and still designed and engineered in the UK, Soundcraft defined the term 'British sound' in live sound mixing consoles.Soundcraft Co-Founder Graham Blythe's acclaimed microphone preamps and 'British' equaliser ensures the Si Impact proudly carries Soundcraft's signature sound today.
Going beyond analogue control
Combining One-Knob-One-Function control with unique features like FaderGlow™, Soundcraft combines analogue workflow with digital flexibility. FaderGlow™ illuminates the fader track in different colours to provide at-a-glance status information on precisely what the fader is controlling – aux sends, FX sends or even the graphic EQ that's available on every bus.Each fader channel also features a clear multi-color LCD display - giving 'at a glance' information on levels and offering a fully customisable'scribble strip' to name your channels.
World-class effects & dynamics
Si Impact isn't just packed with DSP power. It's packed with DSP power from the acknowledged experts in digital FX. That means studio-grade reverbs, delays and modulations from Lexicon, legendary dbx dynamics and industry-standard BSS Graphic Equalisers.Put your I/O where you need it
With built-in connectivity for an optional Soundcraft Stagebox, Si Impact lets you put your I/O where you need it.Set up your Stagebox by the band for live sound applications, or position it in the live room for studio recording all via a single piece of Cat 5 cable.
