Analog Simplicity, Digital Flexibility

The Soundcraft Si Impact digital mixer not only gives you a simplicity and ease of use that rivals an analog console, but you also get the excellent sound quality that Soundcraft has become known for over the past 40-plus years. You'll love the Si Impact's unique FaderGlow system, which provides you with at-a-glance status information, as well as its ample DSP power, great-sounding 32-in/32-out USB audio interface, and generous I/O options.

Going Beyond Analog Control

Delivers analog workflow with digital flexibility

One of the Soundcraft Si Impact's strengths is that it provides you with a simple analog workflow while also offering you the flexibility that you can only obtain with a digital mixer. One-knob-one-function control means you won't have to jump around the board to change parameters, while the FaderGlow system ensures that you know exactly which functions are being controlled by which faders simply by looking at them. Each fader channel also provides you with a clear multicolor LCD display, giving you quick at-a-glance information on your levels and a fully customizable "scribble strip" to name your channels.

  • Streamlined analog workflow with digital flexibility
  • One-knob-one-function control
  • FaderGlow system
  • Clear multicolor LCD displays

Legendary British Sound

Graham Blyth-designed mic preamps and "British" equalizer

Like all Soundcraft mixers, the Si Impact is positively packed with that highly sought-after "British" sound. Thanks to its stellar-sounding mic preamps (designed by Soundcraft founder Graham Blyth) and 4-band, fully parametric "British" equalizers, the Si Impact provides you with a sound that will imbue your mixes with plenty of classic distinctive character.

  • Sought-after "British" sound
  • Graham Blyth-designed mic preamps
  • 4-band parametric EQs on each channel

World-class Effects

DSP processing from Lexicon, dbx, and BSS Audio

Featuring studio-grade reverb and effects from Lexicon, legendary dbx dynamics, and industry-standard BSS graphic EQs, the Soundcraft Si Impact's onboard DSP carries quite a pedigree. Thanks to these world-class effects, you'll be able to create polished, pro-sounding mixes without a rack full of outboard gear.

  • Lexicon reverb and effects
  • dbx dynamics processing
  • BSS graphic EQs on each bus

Put Your I/O Wherever You Need It

Built-in connectivity and a complete range of I/O expansion cards

With built-in connectivity for their optional stagebox, Soundcraft's Si Impact lets you put your I/O wherever you need it. You can set up the stagebox by the band and route your sound to front of house, or you can position it in the live room for studio recording — all through a single Cat 5 cable. You can also use the Si Impact's 32 x 32 expansion card slot to integrate it with existing systems and hardware that use any of multiple I/O formats, including MADI, CobraNet, Aviom A-Net, AES/EBU, BLU link, RockNet, and Dante.

Very good ! sweetwater saleman very patient

Great investment!

This is the first digital mixer we have in our church. First of all, let me tell you that we were skeptical about this one because of the price, but as soon as we plugged this mixer to our new QSC KW153 speakers (we couldn't have better speakers) we felt like we had discovered fire. The best thing, it's user friendly for beginners. If you're looking for affordable mixer without compromising quality, this is the best option for you.

Nothing Will Hold You Back

I've had this board for several weeks now. I've used it for concerts (large multi-speaker FOH), a little studio work, and to run a full on production of Peter Pan (if you know the show, then you know it's demanding). Can't believe how easy it was to really learn a new board and become proficient on a professional level. The on board procession is astounding the Variable HPF, Gate, and Compressor really narrow down your signal to exactly what you want to work with, and of course a huge range to work with on the EQ. Plenty of In's and Out's to really Taylor to any situation I need. I have my own system, but often contracted to work in a location that already has the PA (FOH and monitors) already wired and set, so you really need a board that will cover any situation, and I haven't had any issues yet. Programming custom Fader layers, being able to decide what you work with on each layer is crucial to most of what I do. Only real complaint I have is I do wish there was a on-screen setting to view All the Input levels and/or All the output levels, but the screens provide so much visual feedback, that it was something I could do without. Definitely recommended for FOH for anything from simple needs to full on productions, suitable for studio work but definitely optimized for Live Audio.

Si impact & Stagebox R32

I took my new Soundcraft Impact out with my ever so sweet Soundcraft R32 Stagebox and Oh My Word Soundcraft!!!! With a 200 ft cat5 and my iPad remote in hand what an awesome Awesome setup you have created for us on the fly sound Engineers. The days of the 2 or 4 (Aux) monitor mixes are gone, gating, comp, EQ'n all from the iPad,DONE! Don't get me wrong I love running the Yamaha CL48 but I can't carry that thing around and everything I can do on the CL I can easily do on the Soundcraft Impact. This board is so simple anybody could (almost LOL) do sound. Thank you Soundcraft!!!
