Drawing on more than a decade of experience in the field of digital audio mixing, the Soundcraft Si Expression exploits some of the newest DSP, component technology and manufacturing techniques to deliver our most powerful cost effective digital console ever! Each console in the range is identical in its feature set so your only choice is how many faders and local mic amps you want. With a range covering the super portable 19″ rack mount Expression 1 to the mighty Si Expression 3 with its 30+2 faders and 32 mic/line inputs there is a model to meet all needs. 

The Si Expression 1 features 16 recallable mic pre amps (24 on Si Expression 2) plus 4 line inputs, 4 internal stereo FX returns, AES in, and a 64×64 expansion slot offering more than enough scope to use every one of the 66 input processing channels. Every input processing channel has dedicated processing for high pass filter, input delay, gate, compressor and four band EQ whilst keeping it under control is a comprehensive automation system augmented with four mute groups and FaderGlow™ to light the way so you are never lost. 

All Si Expression consoles have busses, output processing and connectivity to match the versatility of the inputs; the 14 aux/group mixes can be configured as 14 mono mixes, 8 mono plus 6 stereo mixes or almost anything in between, whilst the 4 matrix mixes can be mono or stereo as needed. The bus and matrix mixes are complemented with four more mix busses dedicated to the internal Lexicon FX processors all in addition to the left, right and centre busses. Each bus mix features a compressor, 4 band EQ, BSS graphic EQ and delay always available all of the time. Output connectivity is comprehensive with all models featuring 16 balanced line outputs, headphone monitor out, AES out and of course the 64×64 option slot. 

To complement the channel and bus processing all Si Expression consoles integrate four stereo Lexicon FX processors based on the MX400 providing a wealth of sounds, user adjustable parameters and dedicated tap-tempo keys. As the FX are hardware based, use of all the effects, even on the most demanding programmes does not affect other processing in any way and all dynamics, EQs, filters, delays, and GEQs remain available regardless what you are doing.
