Si2+ (discontinued)

Rotary encoders and OLED screens on every channel

The Soundcraft Si2+ is the big brother to Si1+ and will appeal to those wanting a compact and highly-featured digital console at a competitive price. It expands on the original Si2 through the addition of 16 more mic inputs, word clock out as standard and the option to swap the 16 mic inputs for an 8 mic input + 8 line output module if required.

The Si2+ comes in a larger footprint than its smaller brother and has 64 mic inputs mapped on 24 faders and four banks giving simple access to all channels whilst never losing sight of the stereo and FX returns. Like the Si1+ & Si3+ there are four dedicated Stereo Line channels, four dedicated FX Returns from the four stereo Lexicon FX processors, 8 balanced insert sends and 8 balanced insert returns. Si2+ is completed with 24 Group/Aux busses available at all times, 8 matrix busses plus a full complement of monitor talkback and main bus outputs. The four 64x64 channel expander slots allow the installation of further I/O sources including the connection of Soundcraft and Studer stageboxes. A direct out from every mono channel offers a simple way to record every channel whether requiring this for later mix-down and production work or to use as a virtual sound-check at the next gig!

Like the Si3+ and Si1+, the Si2+ uses a combination of rotary encoders and OLED screens on every channel so the engineer mixes at source, without recourse to a central screen, an interface welcomed by many engineers. Four assignable on-board Lexicon effect engines supplement 4 stereo inputs to provide a really powerful mix package. Soundcraft’s offline editor program, Virtual Si, can be used to setup and manage complete shows offline, for later download to the console through a USB memory key.

This console is perfectly suited for installations where space restricts placement of a ‘full size’ console such as Theatres, Houses of Worship and smaller Tour Sound systems.

With all input and output connections and power supply on board, the Si2+ can simply drop in where an existing analogue console sat utilising existing copper cable snakes and splitter systems.

Connectivity

On the rear of this highly-featured console are all the I/O connectors you’ll need. Sixty-four XLR’s for the mic/line inputs, 4 stereo line level inputs, 24 bus output XLR’s, Left/Right/Centre mix output XLRs, Left/Right/Centre monitor output XLRs and comprehensive internal and external talkback and Oscillator connections. There are also 8 analogue insert connections which allow outboard processing to be inserted into any input channel output bus.


Offline Editor - Virtual Si

To compliment the Soundcraft Si3+, an offline editor (Virtual Si) is available for managing your show files offline.
