Soundcraft Si Impact - 40-Channel Digital Mixing Console with 32 Combo/8 XLR Inputs and 32-Channel USB Recording

The Soundcraft Si Impact is a feature-packed 40-channel digital mixing console that delivers exceptional audio quality, ease of use, and powerful DSP capabilities for live sound and recording applications. With 32 recallable mic preamps and 8 additional line inputs, it's designed to handle a wide variety of audio sources, providing unmatched flexibility in both live performance and studio environments. The console's combination of analog-style simplicity and cutting-edge digital features, such as the FaderGlow system and a pristine 32-in/32-out USB audio interface, makes it a perfect choice for engineers seeking high-quality sound without compromise.

The Si Impact's free V2.0 firmware update unlocks even greater potential, doubling the console's mixing channels from 40 to 80 when combined with the built-in USB inputs. By adding a Soundcraft Mini Stagebox or an optional second MADI card, users can extend the system's capabilities to handle up to 128 total inputs and 80 channels to mix. This added flexibility allows the Si Impact to adapt to a wide range of configurations, from small gigs to large multi-stage events. The built-in 32-in/32-out USB interface makes it easy to connect to a DAW, enabling seamless multi-track recording and playback with any PC or Mac.

Designed to provide the tactile feel of an analog console, the Si Impact features Soundcraft's One-Knob-One-Function control, allowing instant access to key parameters without diving into menus. The FaderGlow system offers visual feedback by illuminating each fader track in different colors, letting you know at a glance what the faders are controlling, whether it's aux sends, FX sends, or graphic EQs. Each fader is motorized and features a multi-color LCD display that provides information on levels and customizable channel names, ensuring clarity and ease of use during live performances.

With powerful DSP from industry leaders like Lexicon, dbx, and BSS, the Si Impact delivers studio-grade effects and dynamics processing on every channel and bus. The four stereo Lexicon FX engines provide a wealth of presets, including reverbs, delays, and modulations, while dbx compression and BSS graphic EQs are available across all busses for complete control over the mix. The console also includes dedicated tap-tempo switches, enabling real-time adjustments for delay effects and other time-based processing.

The Si Impact's versatility extends beyond its built-in features, with expansion options via the ViSi Connect 32x32 expansion slot, enabling integration with Dante, MADI, and other digital audio protocols. This allows the console to interface with Soundcraft stageboxes, providing remote I/O capabilities for both live sound and studio applications. Additionally, the Soundcraft ViSi Remote iPad app gives you control over the console from anywhere in the venue, allowing you to mix monitors from the stage or adjust the FOH mix from different audience positions.

Built with the high standards of Soundcraft's British heritage, the Si Impact features 32 recallable mic preamps with phantom power indicators, ensuring top-tier sound quality and reliability. The robust construction and intuitive layout make it suitable for both professional audio engineers and those transitioning to digital consoles from analog setups. Whether used for live sound, recording, or broadcast, the Si Impact offers a powerful and flexible solution with the superior audio performance Soundcraft is known for.
