Click the "More Info" tab to download complete details on the features & options of the Si Expression.Along with many new technologies and features, the Si Expression borrows much from its predecessors the Soundcraft Si Series consoles and Soundcraft Vi series, ensuring high reliability, fantastic audio quality and a mature and comprehensive feature set available at an incredibly competitive price.The Soundcraft 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 64x64 option slot. To complement the channel and bus processing all Soundcraft 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.
