Description
The Soundcraft Si Expression 2 Digital Mixer is a digital mixing console designed for live sound applications. The mixer features 24 microphone preamps, 4 line inputs, AES in, 4 internal stereo FX returns, 22 faders, a 64 x 64 expansion slot for additional routing possibilities, and 66 input processing channels.
Every input processing channel on the board can be routed through a dedicated high-pass filter, input delay, compressor, gate, and four-band equalizer. Each channel is also under the control of an automation system with four mute groups and illuminated faders to keep track of signal processing. For outputs, the mixer includes 16 balanced line outputs, a headphone monitor output, AES output, and the 64 x 64 expansion slot.
