Soundcraft Si Impact 40-input Digital Mixing Console

The Si Impact is a compact yet feature-rich digital console that delivers professional mixing capability in a genuinely portable format. Its 26 motorized faders, responsive 5" touchscreen, and intuitive layout make it equally at home in live sound, broadcast, or installation work. This is a serious mixing tool that doesn't demand a truck to transport.

I/O Architecture & Connectivity

With 40 DSP input channels (32 mono inputs plus 4 stereo returns), 31 output busses, and 20 sub-group/aux busses, the Si Impact handles complex routing demands without compromise. The 32 XLR mic inputs with switchable phantom power (arranged in groups of eight) plus 8 combi-jacks for line and instrument sources provide flexibility for any signal chain. The 32-in/32-out USB interface integrates seamlessly with recording systems, while the 32×32 expansion card slot supports MADI, Dante, CobraNet, AES/EBU, and other professional networking protocols.

Processing & Control Surface

Each channel and bus carries a 4-band fully parametric EQ plus access to four studio-grade Lexicon Effects engines with dedicated FX busses, while BSS Graphic Equalisers are available on every output bus. The control surface features 26 motorized faders across 4 fully customizable fader layers, 8 VCAs, and 8 mute groups, allowing rapid reconfiguration and recall during sessions. The multi-colour LCD channel displays paired with the 5" touchscreen create an efficient mixing environment that rewards both quick decisions and detailed work.
