Si Expression Series Digital Mixing Console

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 their 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.

The Si Expression Series features up to 32 recallable mic pre amps plus 4 line inputs, 4 internal stereo FX returns, AES in, and a 64x64 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.  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 64x64 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.

• Assignable Fader Layers — Customise each of the four fader layer pages to meet your needs or add/insert faders to accommodate that additional mic that was not in the patch list!
• 1 Control = 1 Function — With each control dedicated to a given function there is never any 'layering' of controls or navigating through screens; this allows the Si Performer controls to be labeled on the surface just as they would have been on an analogue mixer.
• TOTEM — The One Touch Easy Mix; press a single key to mix to an AUX, FX or Matrix bus, the surface and monitoring instantly reconfigure to allow instant mixing to your chosen bus on the faders.
• Soundcraft FaderGlow — Illuminates the fader slots according to function with clearly defined colours for FX, Stereo, Linked Mono, GEQ, POST Fade Aux, PRE Fade Aux; you'll never be lost again!
