The Soundcraft® Si Expression draws on more than a decade of experience in the field of digital audio mixing, exploiting some of the newest DSP, component technology, and manufacturing techniques. Each console in the series 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 Si Expression 3 with its 30+2 faders and 32 mic/line inputs, there's a model to meet all needs.

NOTE: The Si Expression 2 can work in conjunction with the DBX TR1616 digital network device and the DBX PMC16 16-channel personal monitors WITH the purchase of the BSS BLU-SI card. Please contact your sales representative for more information on this and other products.  

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, and 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 center busses. Each bus mix features a compressor, 4 band EQ, BSS graphic EQ, and delay always available all of the time. All models feature comprehensive output connectivity with 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 4 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.

Flexible onboard and expansion I/O options ensure your Si Expression integrates effortlessly with other system components utilizing any of the Si series option cards including AES, Firewire/USB/ADAT, AVIOM™, CobraNet™, BSS Digital Audio Bus (BLU Link), Dante™ CAT5, or optical MADI. The MADI card, as well as being an interface to multi-track recording systems or plug-in systems like Waves, enables the Si Performer to link to any of the Soundcraft or Studer stageboxes for extended I/O power and flexibility. Adding a stagebox to an Si Expression actually increases the number of channels you can mix at once not just how many inputs you have available to choose from!

As you would expect from any Soundcraft digital mixer, the facilities are extensive and include legendary audio quality courtesy of the latest generation EMMA™ DSP processor, the same DSP platform that has helped propel previous Soundcraft Si series consoles to fame. All this power blended with reliability, flexibility, and usability puts the Si Expression in a class of its own.
