The Soundcraft Si Expression 1 Digital Mixer is a digital mixing Digital Mixer designed for live sound applications. It features 16 microphone preamps, 4 line inputs, AES in, 4 internal stereo FX returns, 14 faders, a 64 x 64 expansion slot for additional routing possibilities, and 66 input processing channels.

The Soundcraft Si Expression 1 Digital Mixer is a powerful cost effective digital Digital Mixer. Drawing on more than a decade of experience in the field of digital audio mixing, the Soundcraft® Si Expression 1 Digital Mixer exploits some of the newest DSP, component technology and manufacturing techniques to deliver Soundcraft's most powerful cost effective digital Digital Mixer ever! Each Digital Mixer 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 Soundcraft Si Expression 1 Digital Mixer features 16 recallable mic pre amps (24 on Si Expression 2 and 32 on Si Expression 3) 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 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 Digital Mixers 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 Digital Mixers 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.

Flexible onboard and expansion I/O options ensure your Soundcraft Si Expression 1 Digital Mixer integrates effortlessly with other system components utilising any of the ViSi Connect™ Si series option cards including MADI USB Combo, BSS Digital Audio Bus (BLU Link), Dante™, CAT5 or optical MADI, AVIOM™, CobraNet™ and others. The MADI card, as well as being an interface to multi-track recording systems or plug-in systems like the Soundcraft Realtime Rack™, enables users to link the Soundcraft Si Expression 1 Digital Mixer to any of the Soundcraft or Studer stageboxes to extend the 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! It is said 'Power is nothing without control' and here the Soundcraft Si Expression 1 Digital Mixer excels with a comprehensive but 'simple to use' control surface incorporating a dedicated control for every parameter, a row of global mode encoders and colour touch screen ensuring operation is quick and easy.

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 Digital Mixers to fame. All this power united with reliability, flexibility and usability puts the Soundcraft Si Expression 1 Digital Mixer in a class of its own.

Soundcraft Si Expression 1 Digital Mixer Highlights

  • Massive mix capacity – 66 inputs to mix in a small format live sound digital mixer.
  • 1 ViSi Connect™ option card slot for 64x64 expandsion of digital I/O including the MultiDigital Card (Firewire/USB/ADAT), BSS Digital Audio Bus (BLU Link), Dante™, CAT5 or optical MADI, AVIOM™, CobraNet™ and others.
  • 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!
  • BSS® GEQ - With a BSS GEQ on every bus there is never any need to assign from a pool of resources and you will never 'run out' of processing.
  • Security Lockout - Lock the whole Digital Mixer or just selected elements, manage the security with the users and profile settings.
  • Personal Monitoring Interface - When used with the Si BLU link option card, the Si Performer is a perfect partner to the dbx PMC16 Personal Monitoring System , using simple Cat5 cabling for easy setup.
  • D.O.G.S. (Direct Out Gain Stabiliser) - Prevents manual change of a mic gain control affecting direct out levels, perfect when 2 Digital Mixers share a stagebox or when recording the channel direct outputs.
  • Global Mode Controls - A row of rotary controls above each fader assignable at the touch of a button to be GAIN, PAN or HPF for all of the inputs allowing instant access to the core functions.
  • Copy & Paste - Copy whole channels, busses, mixes, Lexicon™ effects, a single part such as the EQ or multiple parts like the channel gate and compressor.
  • Instant Access Keys – Dedicated keys on the front panel for STORE, RECALL, NEXT, MUTE 1-4, TAP TEMPO and more negate the need to dive into screen & context menus.
  • Function Focus – Whenever a control is moved or SELect key pressed the screen displays information about the channel identifying the absolute value of the controls and the channel name, number etc.
  • Everything Everywhere – All channels and busses have a full complement of processing, nothing to assign or configure.
