Soundcraft Si Expression 2 24-channel Digital Mixer

The Soundcraft Si Expression 2 is a flexible 24-channel digital mixer engineered for fast, confident control in demanding shows. Its 24 recallable mic preamps, four line inputs, and four stereo FX returns feed a 66-channel mix engine, giving small footprints big-stage capability for FOH, monitors, and installs. Soundcraft’s “1 control = 1 function” workflow, FaderGlow, and TOTEM (The One Touch Easy Mix) keep navigation immediate—press a single key and the surface reconfigures for your chosen bus. A single 64x64 expansion slot accepts ViSi Connect option cards such as Dante option card, MADI, and BLU link, so the console scales easily with stageboxes and networked audio systems.

Processing is always-on thanks to EMMA DSP, with high-pass filter, input delay, gate, compressor, and 4-band EQ on every input, plus compressor, 4-band EQ, delay, and BSS GEQ on every bus. Four stereo Lexicon effects engines are hardware-based, so using reverb or delay never steals resources from dynamics or EQ. Bus architecture is equally versatile: configure 14 aux/group mixes as mono or stereo, add four matrix mixes, and route to LR and Center. Connectivity includes AES in/out, 16 balanced line outputs, headphone monitoring, and stagebox support via the option slot.

Built for real-world reliability, the Si Expression 2 features a color touchscreen for patching, labeling, and setup. Chassis dimensions are approximately 716 × 520 × 168 mm (W × D × H), fitting easily into churches, schools, corporate AV, clubs, and portable rigs that need a compact live sound console with room to grow.
