Soundcraft Si Expression 2 Digital Console

Soundcraft Si Expression 2 Digital Console

The Si Expression 2 combines intuitive motorized faders and a responsive color touchscreen interface that make real-time mixing feel natural and direct. This mid-format digital console delivers transparent audio character across live sound, theater, corporate events, and recording applications, with enough processing power and headroom to handle complex mixing tasks confidently. Its compact yet fully capable design makes professional-grade mixing genuinely enjoyable to work with, night after night.

Mixing & I/O Architecture

Built around 24 recallable mic preamps plus 4 line inputs feeding 66 input processing channels, the Si Expression 2 accommodates large-format mixing without sacrificing signal clarity. Additional AES input, 64x64 expansion slot, and 16 balanced line outputs with AES output and optional expansion provide flexible routing for both analog and digital workflows.

Processing & Effects Engine

Each input channel includes dedicated high pass filter, input delay, gate, compressor, and four-band EQ, giving you surgical control over source material before it hits the mix bus. The console houses four stereo Lexicon FX processors based on the MX400, along with 14 configurable aux/group mixes, 4 matrix mixes, and 4 Lexicon FX buses, providing ample creative options for effects routing and submix organization.
