Amazing flexibility
If you think the Soundcraft Si Expression 1's input side is impressive, you should know that all Si Expression boards also sport versatile bussing, output processing, and connectivity. You can configure the 14 aux/group mixes as 14 mono mixes, eight mono plus six stereo mixes or just about anything in between. The four matrix mixes can be mono or stereo as required. You also get four more mix busses dedicated to the internal Lexicon FX processors, in addition to the left, right, and center busses. Each bus mix features always-available compression, 4-band EQ, BSS graphic EQ, and delay. Comprehensive output connectivity includes 16 balanced line outs, a headphone out, AES out, and the 64 x 64 option slot.

Onboard Lexicon FX processors 
Soundcraft Si Expression consoles incorporate four stereo Lexicon FX processors based on the acclaimed MX400. With fully adjustable parameters and dedicated tap-tempo keys, you can tweak to your heart's content. These FX are hardware-based, so even if you're using a ton of them it doesn't affect your other processing in the slightest. All of your dynamics, EQ, filters, delays, and GEQs will always be available, no questions asked.
