Soundcraft Si Expression 3 32-channel Digital Mixer

The Soundcraft Si Expression 3 is a powerful 32-channel digital mixer engineered for fast, confident control in real-world shows. With 32 recallable mic preamps, four line inputs, and four internal stereo returns, it feeds a 66-channel mix engine that easily handles complex live sound. A single ViSi Connect 64×64 slot unlocks networked expansion—add a Dante option card, MADI, or BLU link to integrate stageboxes and recording workflows without compromising footprint. The surface follows Soundcraft’s “one control = one function” philosophy, complemented by FaderGlow lighting and TOTEM (The One Touch Easy Mix) so you can flip instantly to any aux, FX, or matrix mix.

Every input channel carries always-available processing: high-pass filter, input delay, gate, compressor, and 4-band EQ. Every bus includes compressor, 4-band EQ, delay, and BSS GEQ, plus four dedicated Lexicon processors for reverb and delay that never steal DSP from dynamics or EQ. The bus architecture is flexible—configure 14 aux/group mixes as mono or stereo, use four matrix mixes, and route to LR and Center alongside four FX buses. Connectivity includes AES digital I/O, 16 balanced line outputs, headphone monitoring, and full stagebox support via the option slot.

A color touch screen streamlines patching and setup, while copy/paste and global mode encoders accelerate show prep. The chassis features 30+2 faders and customizable layers, making it easy to park priority channels where you want them. Approximate dimensions are 928 × 520 × 169 mm (W × D × H). From clubs and houses of worship to corporate AV and regional touring, the Si Expression 3 delivers a compact live sound console that scales with your rig and keeps critical functions at your fingertips.
