About Soundcraft Si Expression 1 Digital Mixer - SKU#1948757

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.

This Si Expression 1 console has 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 the Si Expression 1 console integrates 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 Si Expression integrates effortlessly with other system components utilizing any of the ViSi Connect Si series option cards including MultiDigital Card (Firewire/USB/ADAT), 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 Si Expression to any of the Soundcraft or Studer stageboxes to extend the I/O power and flexibility. Adding a stagebox to Si Expression actually increases the number of channels you can mix at once not just how many inputs you have available to choose from.

Soundcraft Si Expression 1 Digital Mixer - SKU#1948757 Features

  • Massive mix capacity - 66 inputs to mix in a small format live sound digital mixer
  • 1 ViSi Connect option card slot for 64x64 expansion 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 - Customize 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 colors 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 console 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 Stabilizer) - Prevents manual change of a mic gain control affecting direct out levels, perfect when 2 consoles 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
