Soundcraft Si Impact 40-input Digital Mixing Console

The Si Impact is a compact digital console that delivers professional mixing capability for studio and project recording environments. Its 26 motorized faders, responsive 5" touchscreen, and intuitive layout make it a serious mixing tool that fits into real-world studio spaces without consuming an entire control room. This console brings multitrack tracking, submix control, and detailed processing to home and mid-size studio setups.

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 multitrack recording sessions and 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 tracking vocals, drums, instruments, and outboard gear. The 32-in/32-out USB interface integrates seamlessly with DAW tracking and mixing workflows, while the 32×32 expansion card slot supports MADI, Dante, CobraNet, AES/EBU, and other professional networking protocols for expanding session I/O.

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, allowing you to shape tone and add depth during tracking or mixing. BSS Graphic Equalisers on every output bus provide final mix correction and problem-solving on the master chain and subgroups. The control surface features 26 motorized faders across 4 fully customizable fader layers, 8 VCAs, and 8 mute groups, enabling rapid reconfiguration and session recall as you move between tracking ensembles, submix arrangements, and final mix work. The multi-colour LCD channel displays paired with the 5" touchscreen create an efficient mixing environment that supports both fast decisions and meticulous detail work.
