Soundcraft Si Expression 3 32-channel Digital Mixer at a Glance:
  • Amazing flexibility

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.

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.

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!

It's a Soundcraft

As befitting any Soundcraft digital mixer, Si Expression boards give you extensive facilities and legendary audio quality, courtesy of the cutting-edge EMMA DSP processor - the same DSP platform that has helped rocket previous Soundcraft Si series consoles to stardom. With prodigious processing power, bulletproof reliability, impressive flexibility, amazing ease of use, and a surprisingly friendly price tag, Si Expression mixers are an outstanding value. Exactly what you'd expect from Soundcraft.

Top Notch

This is a well built console with great FX, bright and easy to see glowing faders so you can't get confused on what sound you are mixing and tons of processing power built in. It sets a higher standard for digital consoles nowadays.

great product!

We use this mixer at our church and so far so good,and sounds great without any issues! the only issues we've run into every now and then is just the learning curves that come with an awesome technology. Other than that,I highly recommend it! The only wish that I would like to add on to this mixer is,the capability to use iphone/android apps for individual monitor mixes. Hopefully soundcraft is working on that. As always,Thank you Scott Bennett(X1738) for your wisdom and providing us an excellent sweetwater service...

A LOT Of Bang For The Buck

This console is a LOT of bang for the buck and is a great value!! I am very impressed! The layout of the work surface and architecture are very intuitive and the color-coded faders make it very easy to navigate, especially for those who are either new to digital consoles or for "green" volunteers. As an example, I had a relatively new volunteer with zero experience with digital consoles almost flawlessly mix a show with only 15 min of instruction (and that was during sound check). The construction is solid and the processing capabilities are impressive, especially for a console in this size and price range. The few limitations that I found (none of them "show-stoppers") were all things that I would not have expected to find in a console in this price range and there were work-arounds for all of them. The I/O's make for an easy DIY installation, if you are replacing an existing console. The Visi Remote app is very responsive and provides almost complete control with virtually no latency.I am very impressed!!

Sweetwater Advice

Kenny Bergle

The Si Expression 3 is a great board with SO MUCH flexibility and great Soundcraft audio quality! Just the fact that you can lock out the trim pots on the mic pres makes it a great choice for any venue that uses volunteer sound people (like churches). Also there's a really cool feature that Soundcraft calls "FaderGlow®". It makes pretty colors on the fader strip, color-coded and clearly defined colors for FX, Stereo, Linked Mono, GEQ, POST Fade Aux, and PRE Fade Aux. Not only are they very cool to look at, it's now easy to tell at a downward glance where in the mix you are. With included Lexicon Reverb, BSS GEQ, and other Harman partner advancements, it is THE board to get! I'm STILL not believing how affordable it is as well! AND with all the optional expansion cards (including AES, Firewire/USB/ADAT, AVIOM, CobraNet, BSS BLU Link, Dante, optical MADI), it's an audio recording computer interface extraordinaire! With a Soundcraft Mini Stage Box, you've got a whole snake/console solution for a fraction of former analog pricing with modern digital audio quality and computer connectivity/control. Wow!!
