Soundcraft Si Expression 1 16-channel Digital Mixer
 
The Soundcraft Si Expression 1 is a compact digital mixer built to move fast in real shows without sacrificing depth. Its 16 mic preamps feed a 66-channel mix engine, so even small footprints can run serious live sound. A single 64x64 expansion slot accepts ViSi Connect option cards—think Dante option card, MADI, BLU link, and more—so you can drop this console into touring rigs, fixed installs, or campus AV without rewiring your world. Soundcraft’s “one control = one function” surface and FaderGlow lighting keep navigation obvious, while TOTEM (The One Touch Easy Mix) flips the faders to your chosen bus in an instant.
 
Under the hood, Lexicon delivers four stereo Lexicon effects engines; BSS provides BSS GEQ on every bus; and the EMMA DSP platform handles gates, compressors, and 4-band EQ on every input and bus—always available, no resource juggling. Connectivity covers AES in/out alongside 16 balanced line outputs and headphone monitoring, with stagebox support via the expansion slot for remote I/O.
 
Road-ready construction includes a polycarbonate-covered surface and a color touch screen for patching, system setup, and security lockouts. Dimensions are 482 x 520 x 168 mm (W x D x H), with a 445 mm width when rack ears are removed, and a weight of 11.8 kg (26 lb). Ideal for churches, schools, corporate AV, and club FOH, the Si Expression 1 balances speed, power, and reliability in a small-format mixer that scales as your system grows. When you need straightforward control today and networked expansion tomorrow, this live sound console hits the sweet spot.
