Robust automation and connectivity are the icing on the cake. Take your mixing to the next level, with Soundcraft's Si Expression 3. The Si Expression 3 gives you 32 recallable mic preamps, four line inputs, four internal stereo FX returns, AES in, and a 64x64 expansion slot that lets you deploy up to 66 input processing channels - each sporting a highpass filter, input delay, gate, compressor, and four-band EQ. Amazing flexibility If you think the Soundcraft Si Expression 3's input side is impressive, 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 - all 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 64x64 option slot. Say goodbye to digital mixer confusion Soundcraft's Si Expression mixers feature a 1 Control = 1 Function interface, with each control dedicated to a single function. No confusing control layering or endless menu purgatory navigation. This approach allows the Si Expression controls to be labelled on the surface just as they would be on an analog desk. Ah, productivity - how refreshing! 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 your dynamics, EQ, filters, delays, and GEQs will be always available, no questions asked.
